Description

Technical Field

[0001] The utility model relates to the technical field of imaging equipment, and more specifically to a portable mobile DR medical imaging equipment based on a flat-panel X-ray source. Background Art

[0002] With the continuous development of X-ray imaging technology, X-ray imaging equipment such as DR and CT have become an indispensable means of modern medical diagnosis and treatment. At present, medical X-ray imaging equipment mainly uses hot cathode X-ray tubes, which have the disadvantages of high power consumption, large size and poor portability. Most of the current X-ray imaging equipment cannot meet the needs of on-site medical diagnosis and treatment in emergencies and complex environmental conditions.

[0003] Cold cathode X-ray sources have the characteristics of miniaturization and low power consumption. Cold cathode X-ray sources have evolved from single-focus and multi-focus to flat-panel X-ray sources. Flat-panel X-ray sources contain a large number of miniature cold cathode X-ray sources, which can achieve close-range imaging and also have the advantages of addressable emission. Low-cost, portable DR imaging equipment can be prepared using flat-panel X-ray sources.

[0004] There are already trolley-type and vehicle-mounted mobile X-ray devices on the market, but they still have problems such as not being compact enough, inconvenient to carry, and difficult to move, and cannot be adapted to special applications such as field rescue and earthquake relief. To this end, this patent proposes a portable mobile DR medical imaging device based on a flat-panel X-ray source. Utility Model Content

[0028] The equipment base 4 includes a lifting beam 401, a basic rod 402, a rotating shell 403, a flat-panel X-ray source 404, a guide rail 405 and a regulating mechanism 6. A vertical groove in a vertical direction is opened on the mounting seat 3. The lifting beam 401 passes through the vertical groove of the mounting seat 3, and the lifting beam 401 is slidably arranged in contact with the inner and outer walls of the mounting seat 3. The driving end of the driving assembly 5 is connected to the lifting beam 401. The basic rod 402 is arranged outside the side wall of the lifting beam 401.

[0029] The flat X-ray source 404 includes a cathode substrate 4042 and an anode substrate 4041, wherein a nano cold cathode 4043 is disposed on the cathode substrate.

One end of the second connecting rod 604 is connected to the end of the flat-panel X-ray source 404 that exceeds the edge of the rotating shell 403, and the other end is connected to the output end of the second regulating cylinder 603, so that the second regulating cylinder 603 can drive the flat-panel X-ray source 404 to slide outward in the concave part of the rotating shell 403 along the guide track 405.

[0035] The driving assembly 5 includes a positioning base 501, a driving cylinder 502 and a connecting beam 503.
