Description

Laser lamp and ionization chamber jack integration module

Technical Field

The utility model relates to the technical field of medical equipment, specifically be a laser lamp and ionization chamber jack integration module.

Background

In 2008, the World Health Organization (WHO) promulgated a 5-year survival rate of tumor patients around 55% in the world today, with a 23% contribution rate from radiotherapy, 25% from surgery, and 7% from chemotherapy. Radiotherapy is one of three major therapeutic methods for tumors. External irradiation means non-invasive operation in which radiation is incident on the body from outside the body, and includes linear accelerator (LINAC), cobalt-60 radiation source, proton and heavy ion radiation source. The radiation is incident on the tumor area from a coplanar or non-coplanar direction and is superimposed and focused on the tumor area so that the tumor area accumulates a high dose while normal tissue exposure is relatively low. The tumor is systemic, and the larger the radiation selective irradiation space is, the better the blind area is. The larger incidence space can better arrange the incidence of the beam, and the normal organs can be better avoided and protected.

Radiotherapy refers to the treatment of tumors by using rays generated by a radiation source, wherein the rays can be irradiated from the outside of the body, or the radiation source can be placed in the tumor to be irradiated from the inside, and the purpose of destroying the tumor or controlling the growth of the tumor is achieved through the physical, biological and chemical actions of the rays and the tumor. "radiosurgery (SRS)" refers to a radiation therapy technique characterized by a relatively small number of higher doses. "Image Guided Radiation Therapy (IGRT)" refers to a radiation therapy technique that uses image guided techniques to achieve precise patient positioning guidance. The "tomotherapy" refers to a radiotherapy technique in which the therapy head rotates one section of tumor each time or the therapy bed continuously steps and the therapy head continuously rotates. "Intensity Modulated Radiation Therapy (IMRT)" is a radiation therapy technique that intensity modulates the radiation flux and field size, including the later developed volume intensity modulated (IMAT, VMAT, ARC) techniques. For convenience, the term "radiation therapy" herein encompasses the radiation therapy techniques described above, unless otherwise indicated.

A spiral tomographic radiotherapy apparatus represented by TOMOTHERAPY of the Mesocuclear An Kerui. The treatment couch carries the patient to continuously advance, the accelerator continuously rotates on the annular frame, and the spiral tomography radiotherapy is implemented. Step-wise tomotherapy, represented by the united states peacock knife system. The rack rotates for a circle to complete the radiotherapy of one fault, the treatment couch advances for a certain distance, the rack rotates for a circle again to complete the radiotherapy of one fault, and the process is repeated to complete the radiotherapy of all the faults.

Image Guided Radiation Therapy (IGRT) systems include systems based on C-arms, ring frames, robotic arms, and the like. The C-arm system is a system in which the radiation source is mounted on a cantilever structure and rotates around the isocenter, and is widely used by manufacturers such as warian, swedish hospital da, siemens, germany, and kandong xinhua. The annular gantry system means that the radiation source is mounted on an annular gantry, and the annular gantry rotates around a center, such as TOMO of An Kerui, guangdong medium energy accelerator, VERO of Mitsubishi, VIEWRAY of America, and the like. The robotic system is one that utilizes a robotic arm with 6 or more degrees of freedom to carry an accelerator, node-type irradiation, such as the wave jet knife of An Kerui, usa.

The imaging system in each radiotherapy system is a system for imaging before and during treatment, and is mainly used for positioning before treatment, detecting position during treatment, guiding and tracking a target area, and comprises kilovolt X-rays, megavolt X-rays, nuclear magnetic images, PET and the like. Multi-modality imaging refers to imaging in multiple modes such as cross imaging and CBCT, and provides 2-dimensional (2D), 3-dimensional (3D), 4-dimensional (4D) image guidance, real-time tracking, and online adaptive radiotherapy for radiotherapy. The imaging system of the radiotherapy equipment is used for imaging the patient before or during treatment, so that the patient is placed at the correct position. Such devices include single plane imaging (DRR), cross imaging systems (2 sets of imaging devices positioned at an angle, 2 sets of DRR) and cone beam volume imaging (CBCT), where a single imaging device can be imaged at an angle to form a single plane 2D image, and can also be rotated around the patient to generate a 3D CBCT image. The cross imaging system is provided with two sets of imaging devices, and can be used for single-plane imaging, double-plane cross stereo imaging and CBCT image rotation.

Radiation source refers to a device that generates radiation, such as: x-ray, electron beam, proton beam, heavy ion beam generated by accelerator, and gamma-ray and neutron ray generated by radioactive source. Accelerator radiotherapy systems use medical accelerators to generate X-rays and electron beams, including conventional accelerators, beam knives, X-ray knives, and the like. Gamma knife and cobalt-60 radiotherapy machine are devices using cobalt-60 decay to generate gamma ray as radiation source. Proton and heavy ion therapy equipment is equipment for generating protons and heavy ions by utilizing devices such as a cyclotron, a synchrotron and the like.

Overall goal of radiotherapy: (1) Irradiating the highly conformal dose distribution to a tumor region or a target region, wherein the tumor obtains enough dose; (2) Normal tissues are well protected by very low dose; (3) accurate positioning guide of the image and accurate tracking of the tumor; (4) The dynamic tumor can be accurately irradiated, and has good respiratory motion management capability.
