2, saved in the main frame that image is processed and display circuit, more power saving, volume can be more small and exquisite, can make fully and the general size of the probe of common B ultrasound diagnostic apparatus, and this hand-held B ultrasound diagnostic apparatus accomplishes that really the complete machine hands holds;
3, the processing of image and Presentation Function have computer to finish, and this hand-held B ultrasound diagnostic apparatus links to each other with computer by the USB interface circuit, therefore have very strong versatility.
Description of drawings
Fig. 1 is circuit structure diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
-as shown in Figure 1, this hand-held B ultrasound diagnostic apparatus comprises probe, operation push-button and main frame and shell, described main frame is arranged in the described shell, described operation push-button is installed in above the described shell, and described probe is installed on a side of described shell, and is positioned at the front end of described main frame.Described main frame comprises filtering operation amplifier, A/D converter, microprocessor, probe drive circuit, usb circuit and operation push-button; Described probe is connected with microprocessor with A/D converter through the filtering operation amplifier, and described probe also is connected with microprocessor through the probe drive circuit, and described microprocessor is connected with operation push-button with usb circuit respectively; Wherein:
Described filtering operation amplifier is used for receiving the detection signal of described probe, and described detection signal is carried out filtering and the backward described A/D converter of processing and amplifying sends.Preferably, described filtering operation amplifier is low noise fully differential single-stage wideband operational amplifier.
Described A/D converter is used for receiving described detection signal, described detection signal is carried out mould/number conversion become digital detection signal, and through microprocessor, send described digital detection signal through usb circuit to computer again.
Described microprocessor be used for to receive the operation information of operation push-button, and controls described probe drive circuit according to described operation information and drive described probe and scan, and sends described digital detection signal by usb circuit to computer.
Described probe drive circuit is used for receiving described microprocessor-based control information, drives probe according to described control information and scans.Preferably, described probe drive circuit is the low-loss stepper motor driving circuit, what use in this drive circuit is that MosFET (field-effect transistor of metal-oxide) is as driving element, the decrease driving power consumption is suitable for the super detector of this hand-held palm B to power saving and the little requirement of volume.
