Abstract

The invention discloses a rear-mounted quality control device, which comprises a test frame. A horizontal installation frame in the shape of Chinese Character "Mu", which is transversely placed, is arranged in the test frame. A plane mounting frame comprises a first transverse sliding rod at the top, a second transverse sliding rod at the bottom, a first supporting rod and a second supporting rodwhich are located on the two sides, a first installation rod for installing a source application device and a second installation rod for installing an ionization chamber, which are located in the middle part. A laser emitter is arranged on the first supporting rod, the emitting end of the laser emitter faces towards the second supporting rod, and the source application device and the ionization chamber are located at the same side of the plane mounting frame. The device can accurately locate the distance between the center of the radioactive source and the sensitive volume of the ionization chamber, and the measurement precision of the activity of the radioactive source is higher; the device can also verify the in-place precision of the radioactive source, and has multiple purposes. The invention further discloses a verifying method based on Monte Carlo Simulation for the rear-mounted quality control device.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an aftermarket quality control device and a verification method based on Monte Carlo simulation. Background technique [0002] Afterloading radiation therapy is an intracavitary treatment that uses manual or remote transmission to transfer one or more sealed radiation sources from the source reservoir to the source applicator at a predetermined position. It has a high dose near the source. , the advantage of rapid drop in dose around the source. In addition, because afterloading radiation therapy directly puts the source applicator into the tumor treatment area, it can reduce the influence of anatomical changes and setup deviations on the dose. Backloading radiation therapy is an effective cancer treatment, especially in cervical cancer radiation therapy has an irreplaceable role. [0003] Quality control is an important part of the radiotherapy quality assurance system. Quality...
