AI Technical Summary
When existing radiation therapy systems track the movement of the target area in real time, they require high-quality, high signal-to-noise ratio complete images, otherwise the location of the target area cannot be accurately calculated, resulting in inaccurate projection of radiation to non-target areas.
Using incomplete or partial images and/or image data, a real-time radiation fluence distribution is calculated by multiplication of the radiation emission matrix (RFM) with these image data to ensure that the radiation energy is projected to the target area at a predetermined dose.
It realizes that radiation therapy can be performed accurately and in real time without high-quality complete images, improving the accuracy and efficiency of treatment.
