Overview




The three-dimensional beam analysis system of the radiotherapy water tank is a modern three-dimensional water tank system. for acceleratorRelevant measures for QA. The system's correct position indicator and perfectly level mechanism significantly reduces setup time. Aluminum and stainless steel components ensure refinement and robustness. Microprocessor controlled, the unit features a dual-channel electrometer and control software with reversible polarity and automatic distance adjustment for quick and easy system setup. The combination of continuous scanning mode and step scanning mode completes the analysis of measurement data in a shorter measurement time.

1. Overview of the device for automatically scanning water tanks in three dimensions

The radiotherapy automatic scanning water tank system adopts automated measurement and control technology, which can quickly, conveniently and accurately scan and measure various types of medical linear accelerators.The radiation field dose distribution parameters of X-rays and electron beams can also be measured for the beam parameters of the MM50 cyclotron, X-knife and 60Co remote treatment machine.

In order to adapt to the requirements of more institutions and customers.

2. Precision mechanical structure

By using a precision mechanical transmission system and a multi-subdivision stepper motor, the system's scanning positioning accuracy is better than0.1mm。

Automatic scanning system: multi-segment stepper motor stainless steel guide rail and slider.

3. Analysis system software




of the systemThe "ray beam analysis system software package" is fully functional and can collect and analyze data, automatically display measured graphics, and calculate various important parameters. It can also convert data into format files required by the radiotherapy planning system. It can adjust the measurement speed, can continuously measure 10 layers of Profile, can scan PPD off center, and can smooth the measurement curve.
