Background
With the development of CT (Computed Tomography) and the improvement of the manufacturing process, in the CT apparatus of the new detector, the number of detectors integrated by the detector array is several times or even ten times of that of the conventional CT detector. The increased number of CT detectors leads to higher and higher resolution of CT images, and the amount of data to be transmitted increases dramatically.
Before the CT device starts scanning, the CT console configures corresponding setting information (such as the number of layers, resolution, etc.) into the data acquisition system according to a scanning protocol, and then the data acquisition system configures the detector array.

In the data acquisition mode, the parameter configuration is carried out on the whole detector array, and the mode of configuring the parameters for the scanning area is not flexible enough, so that the sampling data transmitted to the data acquisition system by the detector array contains a considerable proportion of non-critical area information, and the effective utilization rate of the data bandwidth and the cache space of the data acquisition system is reduced.

With the continuous development of the medical appliance industry, the use of the CT device in the medical field is more common. Fig. 1 illustrates a CT apparatus including: a CT console 101 and a CT gantry 106, wherein the CT gantry 106 further comprises: a data acquisition system 102, a detector array 103, and an X-ray tube 105. During scanning, an X-ray tube 105 emits X-rays to a scanned region 104 (a region where a scanned person is located), and data acquisition is performed through a corresponding detector array 103. Before the CT apparatus starts scanning to acquire CT image data, parameters of the detector array need to be configured, so that the detector array acquires data according to the configured parameters. Taking the CT apparatus shown in fig. 1 as an example, before starting scanning, the CT console 101 issues configuration parameters to the data acquisition system 102, and the data acquisition system 102 configures the configuration parameters into the detector array 103. The detector array 103 acquires data according to the configuration parameters and uploads the data to the data acquisition system 102, and the CT console 101 acquires the acquired data from the data acquisition system 102 to complete acquisition of CT image data.
When the parameters of the detector array are configured, the parameters of the detector array as a whole are configured, and some part of the detector array cannot be configured with the parameters independently. With the continuous development of the manufacturing process, the number of detectors integrated in the detector array of the CT apparatus is increasing, and the amount of data collected by the detector array is increasing dramatically, which brings great pressure to data transmission and storage. The mode of carrying out parameter configuration on the whole detector array ensures that the acquired data acquired by the detector array contains a considerable proportion of non-key area information, thereby not only wasting a large amount of cache space, but also reducing the data transmission bandwidth of a data acquisition system.
The present specification provides a parameter configuration method for a detector array of a CT apparatus, in which each detector module in the detector array corresponds to a different module identifier, and a parameter to be configured in each detector module corresponds to a parameter address, and when performing parameter configuration for the detector array, each parameter can be configured individually in an address management manner. The mode of flexibly configuring the detector array parameters can independently set a key area and a non-key area, acquire data information of the key area as much as possible and reduce or discard data of the non-key area. Therefore, the total amount of the collected data is reduced, the pressure of data transmission bandwidth of a data collection system is reduced, and the effective utilization rate of a cache space is improved.
In order to make the parameter configuration method of the detector array of the CT apparatus provided in the present specification clearer, the following describes in detail the implementation process of the solution provided in the present specification with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2, a CT apparatus is provided for implementing a parameter configuration method of a detector array provided in the present specification, and the CT apparatus includes: a CT console 101, a data acquisition system 102, and a detector array 103; the detector array 103 includes: a plurality of detector modules, each detector module corresponding to a different module identifier; and each detector module corresponds to a plurality of parameter addresses.
The detector array 103 is comprised of a plurality of detector modules, each corresponding to a different module identifier. Taking FIG. 2 as an example, each detector module corresponds to an ID number, such as "ID number-0", "ID number-1", "ID number-n-1", and "ID number-n". Each detector module also corresponds to a plurality of parameter addresses, and each parameter address can be correspondingly provided with a parameter. Taking fig. 2 as an example, each detector module corresponds to a plurality of parameter addresses "addr-0, addr-1, addr-2, … …".
In one example, each of the detector modules corresponds to a plurality of pixel blocks, wherein each pixel block corresponds to a plurality of the configuration parameters; each detector module corresponds to a plurality of parameter addresses, and the method comprises the following steps: the same type of configuration parameters included in the pixel blocks correspond to the same parameter address.
In the above example, each detector module corresponds to a plurality of pixel blocks, that is, each module identifier corresponds to a plurality of pixel blocks, and each pixel block corresponds to a plurality of configuration parameters to be configured. In the above example, the same parameter address is associated with the same type of configuration parameter in the plurality of pixel blocks. For example, in the first detector module, the configuration parameters of the resolution are set for each corresponding pixel block, and all the configuration parameters correspond to the first parameter address. In the parameter address corresponding relation, when the detector array performs parameter configuration on the corresponding parameter address in the detector module, the same parameter address can be used for simultaneously setting the parameters corresponding to the plurality of pixel blocks, so that the parameter configuration efficiency is improved. For example, the resolution of the pixel block corresponding to the first detector module may be directly set to high resolution using the first parameter address.
In another example, each of the detector modules corresponds to a plurality of pixel blocks, wherein each pixel block corresponds to a plurality of the configuration parameters; each detector module corresponds to a plurality of parameter addresses, and the method comprises the following steps: each configuration parameter of each pixel block corresponds to a parameter address.
In the above example, each detector module corresponds to a plurality of pixel blocks, each pixel block corresponding to a plurality of configuration parameters, wherein each parameter of each pixel block corresponds to a parameter address. That is, in the plurality of pixel blocks corresponding to each detector module, each parameter corresponding to each pixel block corresponds to one parameter address. In the corresponding relation, an address management mode is utilized, and independent parameter configuration can be carried out on each parameter address of each corresponding pixel block in the detector module. The mode of configuring the parameters of the detector array is more flexible, and the region to be scanned can be more flexibly set, for example, a certain key region is set to output a plurality of energy spectrum data; the remaining non-critical regions are set to output a single spectrum of data. The independent parameter configuration of different scanning areas is realized, the data information of key areas can be set and collected in a key mode, the data collection of non-key areas is reduced, the bandwidth of a data collection system is saved, and meanwhile the utilization rate of a data cache space is improved.
Referring to fig. 3, fig. 3 is a flowchart of a parameter configuration method of a detector array of a CT apparatus provided in the present specification. The method is applied to the CT device shown in FIG. 2, and the process comprises the following steps:
The description will be made with reference to the CT apparatus shown in fig. 2. Before the CT apparatus starts scanning, a worker sets a relevant scanning region on the CT console 101, for example, a certain region is set as a key region and the region is set as a high resolution; another area is set as a non-critical area and the area is set to a low resolution. After the staff sets the relevant scanning area, the CT console 1001 automatically generates a configuration parameter instruction according to the set parameter information, and sends the configuration parameter instruction to the data acquisition system 102. The configuration parameter instruction comprises a module identifier, a parameter address and a corresponding configuration parameter to be configured. That is, the configuration parameter instruction includes a module identifier and a parameter address for locating a position of the configuration parameter, and also includes a configuration parameter for configuring at the corresponding parameter address.
And 302, configuring the configuration parameters to the parameter addresses under the corresponding module identifiers by the data acquisition system according to the configuration parameter instructions.
After receiving a configuration parameter instruction sent by the CT console 101, the data acquisition system 102 positions a detector module corresponding to the module identifier from the detector array 103 according to the module identifier included in the configuration parameter instruction; and searching a corresponding parameter address from the positioned detector module according to the parameter address in the parameter configuration instruction, and configuring the corresponding configuration parameter at the corresponding parameter address.
The parameter configuration is carried out by using the address management mode, so that the parameter configuration of the detector array is more flexible, and the parameter corresponding to any parameter address in each detector module in the detector array can be independently configured. The mode of flexibly configuring the detector array parameters can independently set a key area and a non-key area, acquire data information of the key area as much as possible and reduce or discard data of the non-key area. Therefore, the total amount of the collected data is reduced, the bandwidth pressure of a data collection system is reduced, and the effective utilization rate of a cache space is improved.
In one example, the data acquisition system configures the configuration parameters to the parameter addresses under the corresponding module identifiers according to the configuration parameter instructions, including: the data acquisition system sends a parameter configuration message to the detector array, the parameter configuration message including a plurality of configuration parameter fields, each of the configuration parameter fields including: the starting identifier, the module identifier, the operation code, the parameter address, the configuration parameter and the verification information; and the detector array configures the configuration parameters to the parameter addresses under the corresponding module identifiers according to the parameter configuration message.
In the above example, after receiving the configuration parameter instruction sent by the CT console, the data acquisition system generates a parameter configuration message according to the module identifier, the parameter address, the configuration parameter to be configured, and the like included in the configuration parameter instruction, and sends the parameter configuration message to the detector array. The parameter configuration message comprises a plurality of configuration parameter fields, and each parameter field comprises: the system comprises a starting identifier, a module identifier, an operation code, a parameter address, a configuration parameter and verification information. The start identifier is used to indicate the start position of a configuration parameter field in the parameter configuration message. The module identifier is used to correspond to a detector module, for example, the module identifier may be an ID number to indicate a detector module. The operation code is used for representing read or write operation and distinguishing read and write actions of the configuration parameter field. The parameter address is combined with the module identifier, so that one configuration parameter field can uniquely correspond to one parameter, and the configuration parameters carried by the configuration parameter field can be configured to the parameter address under the corresponding module identifier. The check information is information for checking the entirety of the configuration parameter field to prevent errors from being generated in the transmission process of the configuration parameter field, and for example, a conventional parity check may be used.
As shown in fig. 4, the present specification provides a data frame as a parameter configuration message. The data acquisition system sends the parameter configuration message to the detector array via the data frame. Referring to fig. 4, the data frame includes a plurality of configuration parameter fields, each of the configuration parameter fields includes: the system comprises a starting identifier, an ID number, an operation code, a parameter address, a configuration parameter and verification information. Each configuration parameter field in the data frame carries an ID number (module identification), a parameter address and a corresponding configuration parameter. Therefore, a mapping relation among the module identification, the parameter address and the configuration parameter is formed, and when the parameter configuration is carried out on the detector array, the parameter configuration can be accurate to each parameter address. Independent parameter configuration of the scanning area can be flexibly realized, for example, a certain area can be set as a key area, and the key area is set as high resolution; the remaining regions are set as non-critical regions and the non-critical regions are set to a lower resolution. Compared with the mode of carrying out parameter configuration on the whole detector array, the acquired data obtained by the parameter configuration mode is more targeted, less data of non-critical areas are included, the cache of a data acquisition system is saved, and the bandwidth pressure is reduced.
In one example, the data acquisition system configures the configuration parameters to the parameter addresses under the corresponding module identifiers according to the configuration parameter instructions, including: the data acquisition system sends the configuration parameters to the detector module corresponding to the module identification according to the configuration parameter instruction; the data acquisition system sends a continuous configuration instruction to the corresponding detector module, the continuous configuration instruction comprises an address interval corresponding to the configuration parameters, the address interval comprises a plurality of continuous parameter addresses, and the detector module configures the configuration parameters to the parameter addresses.
In the above example, after receiving the configuration parameter instruction sent by the CT console, the data acquisition system sends the configuration parameter included in the configuration parameter instruction to the detector module corresponding to the module identifier, and the detector module caches the configuration parameter and waits for the data acquisition system to notify the data acquisition system of performing corresponding parameter configuration. And the data acquisition system sends a continuous configuration instruction to the corresponding detector module, wherein the continuous configuration instruction comprises an address interval corresponding to the configuration parameters, and the address interval comprises a plurality of continuous parameter addresses. And after receiving the continuous configuration instruction, the corresponding detector module configures the configuration parameters to a plurality of continuous parameter addresses contained in the continuous configuration instruction.
The mode of carrying out parameter configuration on a plurality of continuous parameter addresses only needs the data acquisition system to issue a continuous configuration instruction to the detector module, and the detector module can carry out parameter configuration on all the plurality of continuous parameter addresses, thereby improving the configuration efficiency.
For ease of understanding, the following detailed description is given in conjunction with specific cases. A swept volume containing three sections ABC is illustrated in fig. 5. The focus condition corresponding to the part B is complex, and needs to be observed more clearly, so that the part B needs to be set to have higher resolution. In the conventional method for configuring the parameters of the detector array, if the part B needs to be observed more clearly, the whole scanning area containing the three parts ABC needs to be set to be higher in resolution. This results in the data acquisition system acquiring data that includes high resolution data of non-critical areas (AC portions). By using the parameter configuration method of the detector array provided by the specification, the effect of independently setting the parameters of the part B can be realized by means of parameter address management.
Specifically, the description will be made with reference to the CT apparatus shown in fig. 2. When the staff sets the relevant setting of the area to be scanned on the CT console, the B part can be set as high resolution, and the AC parts can be set as low resolution. After the staff completes the setting, the CT console generates a parameter configuration instruction according to the preset corresponding relation between the module identifier and the parameter address and the parameter information set by the staff. And correspondingly setting the configuration parameters as high-resolution parameters at the corresponding parameter addresses for setting the resolution under the module identifiers corresponding to the part B in the configuration parameter instruction. And the data acquisition system configures the high-resolution parameters to the corresponding parameter addresses under the corresponding module identifications through the parameter configuration instructions. Therefore, when the detector array carries out data acquisition according to the configured parameters, the data resolution of the acquired part B is higher, the data resolution of the acquired part AC is lower, and the effect of carrying out independent parameter configuration on the part B of the key area is realized.
As shown in fig. 5, the complete rectangular region where the part B is located may be configured to have a high resolution, and the resolution of the corresponding rectangular region where the part B is located is higher in the CT scan data obtained after the scanning. Therefore, the image data meeting the diagnosis requirement can be obtained by one-time scanning, high-resolution data output of all regions is avoided, and the total amount of the acquired data is reduced. For another example, in the process of multi-energy spectrum scanning, if it is desired to perform energy spectrum analysis on the B part, we can configure the parameter address corresponding to the B part to "output multiple energy spectrum data", and configure the parameter address corresponding to the AC two parts to "output single energy spectrum data". After the detector array configured in this way is scanned, a plurality of energy spectrum data are output in the data part corresponding to the part B, so that the requirement of energy spectrum analysis in diagnosis is met, and a single energy spectrum is output in the data part corresponding to the part AC, so that the data volume is reduced on the whole. By using the parameter configuration method of the detector array provided by the specification, the effect of independently configuring parameters for the scanning area of the detector array can be realized, the data information of a key area can be output by the detector array as much as possible by the addressing parameter configuration mode, and the bandwidth and the cache capacity of a data acquisition system are effectively utilized.
As shown in fig. 6, the present specification provides a CT apparatus, which may perform the parameter configuration method of the detector array of the CT apparatus according to any embodiment of the present specification. The apparatus comprises: a detector array 601, a data acquisition system 602, and a CT console 603;
the detector array 601 includes: a plurality of detector modules, each detector module corresponding to a different module identifier; each detector module corresponds to a plurality of parameter addresses;
the data acquisition system 602 includes:
an instruction receiving module 604, configured to receive a configuration parameter instruction sent by the CT console, where the configuration parameter instruction includes: the module identification, the parameter address and the corresponding configuration parameter to be configured;

Optionally, as shown in fig. 7, the detector array 601 further includes: an identification circuit corresponding to each detector module; the identification circuit is used for outputting the module identification. For example, different electrical signals may be output using resistive networks as are common in the art, and different identification circuits may be output using different electrical signals. The specification does not set any limit to the identification circuit of the output module identification.
Optionally, as shown in fig. 7, the identification circuit comprises a plurality of circuit branches, each circuit branch comprising a resistor and a gating switch in series; and different combinations of gating switch states in each circuit branch correspondingly output different module identifications. Taking fig. 7 as an example, one end of each branch circuit is connected to high level, and the other end is grounded. The gating switches are in two different states of being closed or opened, corresponding to two different electric potentials of the circuit branches, different electric potential signals are output through different combinations of states of the gating switches on the circuit branches, and therefore different module identifications are output through different electric potential signals.
