Compact proton medical CBCT (cone beam computerized tomography) system image detection board unfolding mechanism

Abstract

The present invention discloses a compact proton medical CBCT (cone beam computerized tomography) system image detection board unfolding mechanism. The mechanism includes an image detection board unfolding portion, image detection board half-opening and fully-opening conversion portions and image detection board connecting portions; the image detection board unfolding portion comprises a linear motion mechanism and a crank slider mechanism, wherein the linear motion mechanism is in driving connection with the image detection board mounting seat of the crank slider mechanism to rotate around a shaft; each image detection board half-opening and fully-opening conversion portion includes a linear driver; each image detection board connecting portion includes an image detection board; the linear driver is in driving connection with the corresponding image detection board; and the image detection board is slidably connected onto the image detection board mounting seat. The compact proton medical CBCT (cone beam computerized tomography) system image detection board unfolding mechanism of the invention has the advantages of simple structure, reliable operation and high motion precision. The unfolding mechanism can simultaneously unfold a left image detection board and a right image detection board and does not occupy the space of a treatment room for a long time; and when being matched with a rotary treatment room, the unfolding mechanism can receive the X-ray scanning images of patients in different positions and postures.

Description

technical field [0001] The invention belongs to the field of proton radiotherapy, and relates to an X-ray image detection board deployment mechanism, in particular to an X-ray image detection board deployment mechanism for a CBCT system precise positioning device for a proton medical rotary treatment room. Background technique [0002] Proton medicine is commonly known as "cancer nemesis". The advantage of proton beams in tumor treatment over other radiotherapy modes is that it uses the Bragg peak of proton beams to better conform to the different shapes of tumors. Rays are sharper. Proton therapy only performs fixed-point high-energy irradiation on tumor lesions, which greatly reduces the dose of radiation to healthy tissues and organs around the tumor, can reduce the side effects of organs that are easily affected by radiation, reduce the follow-up effects of radiotherapy, and effectively treat the burden of tumor lesions on the body It is small, and it can also be treate...
