Description

Technical Field

[0002] Precision radiotherapy equipment (such as proton radiotherapy equipment) needs to be accurately installed in the hospital's radiotherapy room, which places high demands on installation accuracy. The existing treatment floors in hospitals often use the construction of surrounding walls as the most common infrastructure method. However, the construction of surrounding walls as infrastructure often has the following problems for the installation of radiotherapy equipment:

[0003] 1. Traditional radiotherapy rooms use reinforced concrete structures. The allowable error of the infrastructure is 10 mm within a range of ten meters. The installation of radiotherapy equipment often requires drilling holes in the wall. Since there are certain construction errors in the infrastructure itself and certain errors in drilling the installation holes, the cumulative tolerance will become larger. This makes it common for precision treatment equipment to exceed the accuracy limit during installation.

[0004] 2. Chemical bolts are usually used to tighten the holes in the wall. The service life of chemical bolts is usually about 3 years. The later maintenance cost is high and cumbersome. In addition, since there are walls all around, the disassembly and assembly of the treatment equipment is cumbersome.

[0005] The utility model solves at least one of the above problems. Utility Model Content

[0073] Radiation therapy is an existing treatment technology, which includes 2D IGRT (2D Image-Guided Radiation Therapy). 2D IGRT uses two-dimensional images to guide radiotherapy. In 2D IGRT, doctors use X-rays or other imaging components to obtain two-dimensional images of the patient's corresponding parts, and then use these images to determine the patient's position and the location of the tumor. This information can be used to guide the positioning and orientation of the radiation source to ensure that the radiotherapy is accurately irradiated to the tumor area and minimize damage to surrounding healthy tissue.

[0074] In the image-guided radiotherapy system, the isocenter is determined in advance, and the intersection of a pair of X-rays is made to coincide with the isocenter. When the patient's lesion needs to be radiotherapy, the patient's lesion only needs to be moved to the isocenter. Therefore, before radiotherapy, the doctor or other equipment user will first enhance the image anatomical features of the obtained X-ray digital image and the DRR (Digitally Reconstructed Radiograph) generated by the planned treatment CT image, and then calculate the offset between the patient's lesion position and the isocenter through two-dimensional-three-dimensional image registration, so as to adjust the patient's position by moving the treatment bed before treatment to achieve accurate positioning of the tumor.

[0075] The offset value of the patient's lesion position and the isocenter is calculated based on the registration of a pair of X-ray images and CT images. The pair of X-ray images is related to the position of the imaging component, the distance and angle from the radiation source to the radiation detector. The position error of the imaging part will cause the offset error of the X-ray image. For example, if the intersection of a pair of X-rays does not coincide with the isocenter, or a pair of X-rays are in the imaging device, it will affect the calculation of the offset value of the patient's lesion position.

[0076] In some specific embodiments, an X-ray source 21 is provided at both ends of the top frame 2, the bottom of the first main frame 7 is connected to the flat panel detector 22 via the first base assembly 15, and the bottom of the second main frame 11 is connected to the flat panel detector 22 via the second base assembly 16. A control handle can be used to control the X-ray source 21.

[0077] By using the X-ray source 21 and the flat panel detector 22, the technical content of the disclosed Chinese invention patent announcement No. CN116850484B (the invention name is: image guidance system and calibration device, position calibration method, radiotherapy equipment) is adopted to solve the technical problems existing in the above radiotherapy. By using the X-ray source 21 and the flat panel detector 22, imaging surfaces are set at the opposite ends of an optical path channel, so that a pair of imaging surface projections are formed when a ray passes through an optical path channel. According to the offset of the central marking point of the pair of imaging surface projections, the offset of the X-ray source 21 and the flat panel detector 22 in the image guidance system can be determined, so as to adjust the position of the X-ray source 21 and the flat panel detector 22. By calibrating the position offset of the X-ray source 21 and the vertical offset of the ray and the flat panel detector 22, the position accuracy of the X-ray source 21 and the flat panel detector 22 is improved, thereby improving the surgical accuracy of the patient's lesion during surgery.

[0105] In some specific embodiments, see the attached Figure 4 As shown, the moving assembly 113 includes: two support frames 1131 , two sliding rods 1132 and four sliding sleeves 1133 .

[0107] Due to the connection between the sliding sleeve 1133 and the imaging device 20 , when the imaging device 20 is moved, the sliding sleeve 1133 moves synchronously on the sliding rod 1132 to meet the shooting requirements of the imaging device 20 at different positions.

[0109] The sliding sleeve 1133 can not only move axially on the sliding rod 1132, but also move circumferentially, which causes the imaging device 20 to shake and sway during the shooting process. Through the cooperation between the protrusion 1134 and the notch, the position of the sliding sleeve 1133 is limited, limiting its circumferential movement and ensuring stability during the shooting process.
