Embodiment Construction
[0044] Below according to accompanying drawing and embodiment the present invention will be described in further detail:
[0045] Such as Figure 4 As shown, the following components are installed on the rack of the sickle-type digital radiography system: column 1, sickle arm 2, DR detector 3, light beam device 4, X tube 5, angle encoder 6 and height encoder 7.
[0046] Such as figure 1 , figure 2 with image 3 As shown, the device of the sickle-shaped digital radiography system anti-collision method of the present invention includes a lifting motor and a rotating motor, the lifting motor is installed on the column 1 of the sickle-shaped digital radiography system, and the rotating motor is installed on the sickle of the sickle-shaped digital radiography system The front end of the axis of rotation of the arm 2 also includes a height encoder 7, an angle encoder 6, a control module, a lifting motor drive module and a rotating motor drive module, the height encoder 7 and the...

The invention discloses an anti-collision method of a sickle-shaped digital radiography system, which implements the following steps on a control module: A1. the recorded value ANGLE of pulse number of an angle encoder and the recorded value HIGH of pulse number of a height encoder are read; A2. the judgment of whether a sickle arm descending button HIGH-DO or a sickle arm ascending button HIGH-UP is pressed or not is carried out, if not, the step A4 is carried out; A3. the sickle arm ascending and descending processing sub-procedure SHEN is implemented; A4. the judgment that whether a sickle arm clockwise rotation button ARM-CW or a sickle arm counter-clockwise rotation button ARM-CCW is pressed or not is carried out, if not, the step A6 is carried out; A5. the sickle arm rotation processing sub-procedure XUAN is implemented; A6. the procedure is finished. The anti-collision method of the sickle-shaped digital radiography system of the invention can ensure the sickle arm to have maximum ascending and descending stroke when in rotation to any angle by the matching work of the height encoder and the angle encoder; furthermore, the operation is simple, the positioning time of a DR detector is shortened, the diagnostic efficiency is improved, and the intense working state of a doctor is also alleviated because the DR detector can not be collided with the ground.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anti-collision method for a sickle-shaped digital radiography system. Background technique [0002] The sickle-shaped digital radiography system consists of the following parts: ball tube, sickle-shaped frame, high-voltage generator, imaging work collection station, imaging bed, DR (Digital Radiography, digital radiography) detector, and control box. Sickle racks get their name from the sickle-like shape of their arms. The ball tube and DR detector are respectively installed at both ends of the sickle arm of the sickle frame. The distance between the tube and the DR detector can be adjusted from 1 meter to 1.8 meters according to the photographed body parts. The sickle arm can move vertically on the frame by 40cm to 200cm up and down according to the needs of the photographed part of the patient. At the same time, it can also rotate from -30° to 120°. To meet the...
