Description
Technical field
The utility model relates to X ray Real Time Imaging Technology field.
Background technology
Current, along with the continuous progress of computer technology, image processing techniques and flat panel detector technology, digital Real time radiography develops rapidly.For x-ray imaging system, its focal length is the distance from the radiographic source to the flat panel detector, the size of focal length not only has larger impact to geometry sharpness and the sensitivity of imaging, and to the computed image enlargement ratio, determine that in image, the actual physical size of defective plays an important role.In the imaging process of X ray Real Time Image System, operating personnel can be according to the requirement of imaging, and focusing is adjusted in real time, thereby obtains best picture quality; But because X ray has certain radiation effects to human body, in imaging process, operating personnel can not enter protective equipment inside and carry out focometry, thereby can not facilitate to such an extent that focusing is adjusted in real time.Common way is to rely on the mode of measuring after prior estimation or shutdown to carry out Focussing at present, and measurement efficient is lower, low precision.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of X ray Real Time Image System with the automatic measurement function of focal length; realize the non-contact measurement of focusing, the impact that the protection operating personnel avoid X-radiation effectively improves the focometry precision and measures efficient.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of X ray Real Time Image System with the automatic measurement function of focal length comprises the X-ray machine X, flat panel detector and the mechanical platform that are placed in plumbous room; The below of described X-ray machine X is provided with range finder module; Range finder module and two-way connection of single card microcomputer that is placed in outside, plumbous room.
Described range finder module comprises ultrasonic transmitter and ultrasonic receiver, and described ultrasonic transmitter is connected with the output terminal of single card microcomputer by data line, and described ultrasonic receiver is connected with the input end of single card microcomputer by data line.
Described X-ray machine X, flat panel detector and mechanical platform respectively be placed in plumbous room in support be fixedly connected with.
The principle of work that the utility model carries out focometry is as follows: carry out focal length measurement and measure after the each imaging analysis of X ray Real Time Image System is completed, at first with X-ray machine X and flat panel detector leveling, and move on to the middle position that there is no spacer; Then by the control software in single card microcomputer, range finder module is assigned distance measuring instruction, the ultrasonic transmitter transmission frequency of range finder module is about the ultrasound wave of 40KHz, ultrasound wave reflects after arriving flat panel detector, and the ultrasound wave that reflects is received by the ultrasonic receiver of range finder module; Single card microcomputer can calculate X-ray machine X to the distance of flat panel detector, i.e. focal length according to difference and the velocity of wave of ultrasound wave emission with time of reception.
The beneficial effect that adopts technique scheme to produce is: by range finder module being set in plumbous room, outside plumbous room, single card microcomputer being set, utilize the ultrasound wave focusing to carry out non-contact measurement, and simple to operation, can realize continuous coverage; Utilize the automatic control of single card microcomputer can realize the automatic real-time measurement of focusing, effectively improve the focometry precision and measure efficient, the protection operating personnel avoid the impact of X-radiation.
