Description
Technical field
The present invention relates to a kind of patient's bed that especially in computer tomography (CT) or nuclear magnetic resonance (MRT) process, is applicable to place patient.In addition, the invention still further relates to a kind of method of utilizing model (Phantom) to test imaging diagnostic device and comprise the medical skill diagnostic system of patient's bed.
Background technology
According to prior art, be used for the medical skill method of imaging, as utilize in the computer tomography method or nuclear magnetic resonance method of X ray work, can be with using so-called model to come the dependent diagnostic system, namely except Image-forming instrument (especially computer generated image instrument or magnetic resonance imager), generally comprise that also the system of patient's bed tests.In test, generally has the geometrical relationship of restriction between model and the patient's bed.
A kind of calibration steps of the computed tomography imaging system be used to having focus/detector system that two angles stagger is each other disclosed in DE 10 2,005 048 891 B4.Here, focus/detector system is fixed on the rotating cape.For calibrating, need utilize a model that is disposed on the removable bed.
DE 10 2,005 031 893 A1 relate to a kind of in computer tomography the method for adjusting focal length.What use as model in the method, is spherula or the small cylinder of a dead-soft.
Summary of the invention
The technical problem to be solved in the present invention is, further improve, especially in the reasonable design prior art for the Testing And Regulating method of the imaging diagnosis system on the medical skill.According to the present invention, this technical problem is solved by a kind of patient's bed and by a kind of method that is used for testing the diagnostic system on the medical skill.Advantage and the design hereinafter set forth for patient's bed equally also are applicable to method, and vice versa.To term " test " should broadly understand, it especially is included in the step that is known as " calibration " or " adjusting " in the relevant image-forming diagnose instrument of the prior art.The step that is known as " test " is characterised in that, it is not to utilize actual inspection object (particularly patient), but use be known as " model " and have well-known characteristic and or the object of known configurations implement.
Patient's bed according to the present invention has preferred adjustable service creeper and integrated model.Described model is particularly useful for test pattern quality and radiation dose, and be designed to carry out such as every day or the interval long period just carries out, in the test program that carries out per month.
According to the first embodiment, model is fixedly mounted in service creeper, and especially service creeper is distolateral.And model is designed to all can remain under all running statuses of diagnostic system with service creeper and keeps on the relatively-stationary position, particularly can the patient's on service creeper that couch inspection do not exerted an influence.
According to the second embodiment, model can automatically be fixed on the service creeper, and can take off from service creeper.
In this case, preferably have a plurality of models, these models can automatically be fixed on the service creeper as required, and can take off from service creeper.For the keeping model, be designed with storage capsule, this storage capsule is different from die storehouse, and it can be integrated in being used in patient's bed and support in the pedestal of service creeper.
According to patient's bed of this embodiment design can with imaging diagnostic device, particularly computer tomography instrument or nuclear magnetic resonance imaging instrument in conjunction with and form diagnostic system on the medical skill, this patient's bed can make utilize model implement to the test program that diagnostic system is implemented have following feature (here, test program should be understood as that with explain meaning above on " test " step same meaning):
When the test program of diagnostic system begins, can automatically determine according to selected corresponding operational mode from a plurality of models, adopt which model to be used for test program; Wherein, the selection of operational mode or directly implemented by the user of diagnostic system perhaps arranges automatically according to the parameter that exists in the diagnostic system and carries out;
Automatically take out in the storage container of the model that uses from preferably be integrated in patient's bed, and be fixed on the position of a suitable enforcement test program on patient's bed, especially service creeper is distolateral;
Carry out test program, and obtain the feature of model by diagnostic instruments;
After test program finished, model was returned in the storage container automatically.
The test program that is called as " quality inspection " for example will begin to carry out after diagnostic instruments is connected.
Whole test program is also referred to as overhaul procedure, and it automatically performs fully, thereby has maximized user friendly and process reliability.
Description of drawings
The below will explain two embodiment of the present invention in detail by accompanying drawing.Wherein:
Fig. 1: the schematic diagram that is the first embodiment of patient's bed;
Fig. 2: to show another embodiment of patient's bed with the similar form of Fig. 1;
Fig. 3: be to test a flow chart that comprises the method for the diagnostic system on the medical skill of imaging diagnostic device and patient's bed as shown in Figure 2.
The specific embodiment
Consistent with each other or parts that function is identical in all diagrams all with same designated.
Can see respectively patient's bed 1 in Fig. 1 and Fig. 2, this bed has in displaceable mode and is placed in service creeper 3 on the pedestal.In addition, in Fig. 1 and Fig. 2, also drawn concisely an imaging diagnostic device 6 with rotating shaft A, i.e. the computer tomography instrument.The whole device that is made of imaging diagnostic device 6 and patient's bed represents the diagnostic system 7 on the medical skill.Basic function about this kind diagnostic system please refer to the prior art that this paper beginning is quoted.
In the embodiment shown in Figure 1, a model 4 is fixed on the distolateral of service creeper 3, thereby is integrated in enduringly in patient's bed 1.Model 4 is applicable to the geometry site between definite patient's bed 1 and the diagnostic apparatus 6.As a supplement or possibility, model 4 can be constructed to that the diagnostic system 7 on the medical skill is implemented radiation dose and detects.
Embodiment shown in Figure 2 and the fundamental difference of the embodiment among Fig. 1 are that it has a plurality of models 4, and these models can choice for use.
Except storage container 5, patient's bed 1 also has a conveyer device 8 that is used to automatic transport model 4, and this conveyer device is represented as guide rail at Fig. 2, but in fact also comprises such as miscellaneous parts such as binding clasps.When needed, can model 4 be taken out from storage container 5 by means of this conveyer device 8, transport and be fixed to a mould holder 9 that is placed on the front of service creeper 3, in order to the diagnostic system 7 on the medical skill is implemented test programs.After test program finishes, in a similar fashion model 4 is sent back in the storage container 5 again.
Flow chart among Fig. 3 relates to the patient's bed 1 for the storage container 5 of stored models 4 of being integrated with that is plotted in concisely among Fig. 2.
The test program of the diagnostic system 7 on the medical skill of having illustrated among Fig. 3, the startup of this test program is denoted as first step S1.In next step S2, the operator determines the operational mode of diagnostic system 7 directly or indirectly.Operational mode to be selected especially depends on the type that needs with the inspection of diagnostic apparatus 6 enforcements.
In step S3 subsequently, under selected operational mode, which model is fit to implement test program to the diagnostic system 7 on the medical skill with automatic check.
Will be according to this selection of automatically making in step S4 or S5, the model 4 that taking-up is fit to from storage container 5 also is fixed on the mould holder 9.Under this state, in subsequently step S6 and step 7, carry out test program.At last, after test program finishes, in step S8 and step 9, by means of conveyer device model 4 is sent back in the storage container 5 automatically.Like this, the diagnostic system 7 on the medical skill, that is the computer tomography instrument system is just ready, can use.
