Embodiment 1

[0060] Please refer to the attached figure 1 , with figure 1 It is a structural schematic diagram of an AR positioning and positioning system for radiotherapy in this embodiment. The radiotherapy AR positioning and positioning system includes a chassis (1), a positioning bed (2), an operating table (3), a computer (4), a HoloLens (5), a Kinect (6) and a wire (7);

[0061] Please refer to the attached figure 2 , with figure 2 It is a schematic diagram of the chassis structure of an AR positioning and positioning system for radiotherapy in this embodiment. Described chassis (1) is made of bottom plate (11), bottom wheel (12), height adjustment pedal (13), transverse guide rail (14), circular guide rail (15), fixed block (16), adjusting device (17) Composition; the bottom plate (11) is in the shape of a cuboid as a whole, and height adjustment pedals (13) are installed on the left and right ends of the bottom plate (11); 4 bottom wheels ( 12), 2 transverse guide rails (14)...

Embodiment 2

[0069] The radiotherapy AR positioning and positioning system of the present invention is a novel radiotherapy positioning system based on AR technology, which does not need to manually mark the position of the tumor with physical positioning marking lines on the patient's body, and only needs the medical staff to wear the HoloLens (5 ), project it on the fixed board, and then the patient can be positioned according to the position of the virtual model, which greatly improves work efficiency and saves time.

[0070] What needs to be further explained is:

[0071] The present invention adopts the model making software (3DsMAX, Blend) that is used for modeling and rendering model, imports the model made in the early stage into the development engine that builds the development engine of application environment is Unity, is used for compiling relevant script and compiling software is VisualStudio, uses Vuforia and ARToolKit software are related software development kits (SDK, Sof...

Embodiment 3

[0074] Please refer to the attached figure 1 , with figure 1 It is a structural schematic diagram of an AR positioning and positioning system for radiotherapy in this embodiment.

[0075] The use process and method of the radiotherapy AR positioning and positioning system:

[0076] First, the Kinect (6) will be on the circular guide rail (15), rotate along with the orbit, and simultaneously move left and right along with the circular guide rail (15). The 3D somatosensory camera can scan a three-dimensional object, and can automatically generate a three-dimensional outline of the scanned object on the computer (4) when used together with the computer (4).

[0077] The entire system process is as follows: First, the Kinect (6) 3D somatosensory camera and the computer (4) need to be connected together, and the patient lies on the transparent plexiglass (23) of the positioning bed (2) at a fixed position, and the three-dimensional laser line Locate the position corresponding to...

Abstract

The invention relates to an AR positioning system of radiotherapy. The system comprises a chassis, a positioning bed, an operating console, a computer, a HoloLens, a Kinect and a lead; the chassis iscomposed of base plate, bottom rollers, a height adjusting pedal, horizontal guide rails, a circular guide rail, a fixed block and an adjusting device; the positioning bed is composed of a bed board,supports, transparent synthetic glass and pushing handles; the chassis is connected to the operating console via the lead; and the computer and HoloLens are placed on the operating console. The systemhas the advantages that radiotherapy can be carried out on a patient without a body surface physical mark; the patient can be avoided form repeated positioning, and the radiation absorbed dose and medical cost of the patient can be reduced; the patient is avoided from decrease of positioning precision caused by unclear physical marks in the body surface, and the accuracy of radiotherapy is improved; a doctor draws positioning lines less frequently, and time is saved; the working efficiency is improved; the whole process is clear in ideal, easy to master and includes a shorter learning curve;and different body parts of the patients can be collected.

Description

technical field [0001] The invention relates to the technical field of radiotherapy, in particular to an AR positioning and positioning system for radiotherapy. Background technique [0002] At present, at home and abroad, the positioning and treatment of radiotherapy are mainly performed by physically marking the patient's body. At present, radiotherapy patients need to draw radiotherapy physical marks on the body surface for positioning in radiotherapy. Washing or sweating of the patient will cause the radiotherapy physical marks on the body surface to be blurred, which affects the accuracy of radiotherapy, and even requires repositioning, which increases the patient's absorbed radiation dose and medical expenses, interferes with the normal radiotherapy process, and affects Efficacy of radiation therapy. [0003] At present, the traditional positioning method for radiotherapy is as follows: First, CT scans the corresponding parts of the patient according to the requireme...
