Embodiment Construction

[0029] The digital test device for the mechanical precision of radiotherapy equipment, including the detector 1 adopts the Canadian Polaris Optical Tracking System infrared tracking system, and the detection accuracy is above 0.5mm; it is connected with a computer 6 with an Intel Pentium 4 processor above 2.2GHz, and the accelerator is placed At the lower part of the detector 1, a reflective ball 2 is rigidly fixed on the accelerator head 4, and a reflective ball 2 is rigidly fixed at the front and rear ends and the center of the accelerator bed 3 respectively. When testing the three-dimensional positional relationship between the rotating surface of the accelerator and the isocenter 5, when the accelerator head 4 rotates, the detector automatically tracks the rotation of the reflective ball 2 on the head 4, and simultaneously uses the register of the computer 6 to record, etc. The position of the center 5, according to the collected data, establish a three-dimensional map of t...

Abstract

A digitized testing device for the precision of the radiotherapy machine includes the detector (1), the reflecting ball (2), the accelerator bed (3), the accelerator head and the rotating face (4), the accelerator constant center (5) and the computer (6). The detector is connected with the computer, the accelerator is set in the bottom of the detector and the reflecting ball is fixed in the accelerator head. The three reflecting balls are fixed in the accelerator bed; the detecting software system of the computer includes the data collecting part and the error evaluation part. The testing principle is to track the reflecting ball by the detector to record the moving track digitally of the accelerator head, the bed face and frame. So it can collect the dynamic data and set the comparing analysis of the three-dimensional position map and the perfect map to get the error analysis report. The device can ensure the effect of the radiotherapy because of the digital, the high precision, the dynamic and convenient testing.

Description

1. Technical field [0001] The invention relates to a testing device for mechanical precision of medical equipment, in particular to a testing device for the mechanical precision of radiotherapy equipment such as an accelerator, a simulation positioning machine, and a CO60 machine. 2. Background technology [0002] Radiation therapy is an important method of cancer treatment. It has the advantages of direct and effective treatment effect and prolonging the life of patients for difficult-to-operate parts or patients, so it is widely used. [0003] The mechanical precision of radiotherapy equipment is the key to achieving radiotherapy accuracy. [0004] Existing radiotherapy devices include: accelerators, analog positioning machines, CO60 machines, laser positioning lamps and other radiotherapy machines; however, during equipment installation and long-term use, the mechanical accuracy of radiotherapy equipment has no correct quantitative evaluation. The error of field and ligh...
