Light field detection boardAble to provide high-resolution field images and dose distribution information. It can accurately detect small changes in the edge of the radiation field and differences in dose gradients, and has significant advantages in evaluating the performance of multi-leaf gratings, discovering problems with leaf placement accuracy, and monitoring the symmetry of the radiation field. This high-resolution feature helps radiotherapy technicians promptly detect potential equipment failures or deviations in treatment plan execution, so that appropriate corrective measures can be taken to ensure that patients receive accurate and uniform radiotherapy doses.
Compared with some traditional radiotherapy quality control methods, the light field detection board has higher real-time performance. During radiotherapy, it can be placed directly on the treatment bed to monitor the radiation field of each treatment in real time. There is no need for complex preparations and long waits for data processing, and test results can be obtained quickly and fed back to the radiotherapy team in a timely manner. This allows radiotherapy technicians to adjust treatment parameters in real time during patient treatment, improving the accuracy and safety of treatment. It also greatly shortens the time cycle of quality control and improves the efficiency of radiotherapy equipment.
The radiation field images and dose distribution results presented by the detection board are in an intuitive visualization form, and both radiotherapy technicians and medical physicists can easily understand and interpret this information. By observing the image, you can directly determine whether the radiation field meets the requirements of the treatment plan, and whether there are problems such as occlusion, offset, or dose hot spots and cold spots. This visualization feature makes quality control work simpler and clearer, reduces the risk of misjudgment due to difficulties in data interpretation, and helps improve the work efficiency and communication effect of the entire radiotherapy quality control team.
Light field detection boardDetermination steps:
1. Prepare the detection plate: Select the appropriate light field detection plate as needed, and ensure that its surface is clean and flat.
2. Place the detection board: Place the detection board between the object to be measured and the radiation source to simulate actual exposure conditions. Make sure the position and orientation of the detection plate matches that of the object to be measured.
3. Measure: Use a radiation measuring instrument to measure the detection board and record the radiation dose or energy value. Repeat the measurement multiple times for more accurate results.
4. Analyze data: Import the measured data into the corresponding software for analysis. Software helps doctors and technicians determine whether the radiation source's field size, shape and position are consistent and whether there are any deviations or errors.
5. Adjust parameters: According to the analysis results, if it is found that the irradiation field of the radiation source is inconsistent, the position or parameters of the radiation source can be adjusted to achieve better irradiation effects. This may require re-measurement and analysis until satisfactory results are achieved.
