Description

Medical imaging device and the method and device for positioning imaging region
Technical field
The present invention relates to field of medical device, more particularly to a kind of medical imaging device further relates to position imaging region Method and device.
Background technology
In field of medical device, it is determined that, it is necessary to obtain every inspection result of patient before therapeutic scheme to patient, Including the pivoting results or exposure results for obtaining patient's diagnosis and treatment region, diagnosis and treatment region here is exactly imaging region.At this moment, Medical imaging device is needed to use to have an X-rayed or expose the imaging region of patient.Medical imaging device can be x ray machines, than Such as, the stomach position of patient is had an X-rayed or exposed using stomach x ray machines, the stomach position of patient is imaging region, so that Obtain the stomach x fluoroscopic images or exposure piece of patient.The structures of x ray machines as shown in figure 1, including:One bulb tube part 101, one is examined The control (not shown in FIG.) of circuit block 103 of a part 102 and one is looked into, wherein, bulb tube part 101 is located at examination couch part 102 top, for the patient of perspective or exposure on examination couch part 102 under the driving of control circuit block 103 Diagnosis and treatment position, that is, the imaging region on examination couch part 102;Examination couch part 102, positioned at bulb tube part 101 Lower section, can move along x-axis or y-axis direction in the horizontal plane, under the control of control circuit block 103 by thereon Imaging region is moved to the underface of bulb tube part 101, subsequently have an X-rayed or expose;Circuit block 103 is controlled, for controlling The movement of examination couch part 102 in the horizontal plane, drives perspective or the exposure of bulb tube part 101.
At present, during in the horizontal plane mobile of control circuit block 103 control examination couch part 102, using action bars side Formula:Action bars is set on control circuit block 103, electrically connected with the moving cell of examination couch part 102, doctor is adjusted manually Action bars, sends the movable signal on different directions, and the movable signal that action bars identification is adjusted manually is sent to examination couch After the moving cell of part 102, the moving cell of examination couch part 102 drives examination couch part 102 to exist according to the movable signal Moved on horizontal plane along x-axis or/and y-axis direction.
Fig. 2 is the operation lever structure schematic diagram for controlling circuit block 103 in a kind of x ray machines, as illustrated, action bars can To be moved up in x-axis direction or/and y-axis side, doctor can adjust the action bars manually, send movable signal, control is in inspection The imaging region for looking into a part 102 is moved to the underface perspective of bulb tube part 101 or exposed.Fig. 3 is in operation x ray machines After the action bars for controlling circuit block 103, the schematic diagram shown on control circuit block 103, as illustrated, adjusting manually After the action bars, on the display interface on control circuit block 103, such as based on cartoon interface form (FLC) interface On, there is interface prompt frame 301, point out what the imaging region of examination couch part 102 was had an X-rayed or exposed relative to bulb tube part 101 The shift position at bulb center.
It is difficult to accurately using the imaging region on above-mentioned this mode localization examination bed part 102, because:Action bars By the manual travel direction regulation of doctor, recognize after the movable signal adjusted manually, be sent to the motion list of examination couch part 102 Member, the movement of examination couch part 102 is controlled according to the movable signal by the moving cell of examination couch part 102.In this process In, there is delay between the actual movement of examination couch part 102, that is to say, that doctor's phase in the manual direction regulation of action bars The shift position of the examination couch part 102 of prestige can not real time reaction in the movement of examination couch part 102, cause examination couch part The problem of 102 displacement deficiency or excessive displacement, so as to cause the imaging region on localization examination bed part 102 difficult With accurate.
In order to solve this problem, doctor can rule of thumb estimated delay, travel direction regulation manual to action bars; Or manual adjusting operation bar repeatedly, the accurate imaging region in position is finally obtained on examination couch part 102.But, this two The mode of kind is that by virtue of experience or repeatedly operation is realized, can not often obtain preferable registration effect.Further, in hand , can also whether accurate by the imaging field location of fluoroscopic observation examination couch part 102 after the completion of dynamic regulation action bars, this meeting Increase the whole perspective time of patient.
To sum up, how the imaging region being easily accurately positioned on examination couch part is a urgent problem to be solved.
