AI Technical Summary

Technical Problem

Existing proton beam therapy plans are difficult to optimize, resulting in energy being delivered to at-risk organs or tissues, affecting treatment efficiency and effectiveness, especially in FLASH radiotherapy, where conventional methods are limited and computationally complex.

Method used

By configuring the proton beam system to separate each spot path from other spot paths by a threshold distance, forming parallel or parallel-extending spot paths, dose delivery is optimized, overlap is reduced or eliminated, and the accuracy and efficiency of treatment planning are improved.

Benefits of technology

It achieves a higher level of energy delivery, reduces the impact on non-target tissues, improves treatment time and recovery speed, reduces computational resource requirements, ensures more accurate dose delivery to the planned target volume, and reduces side effects.

Abstract

The present disclosure relates to systems and methods for configuring a proton beam system to deliver energy to a patient. Provided herein are systems for configuring a proton beam system to deliver energy to a patient. In some examples, the system can include one or more processors configured to receive scan data associated with a three-dimensional scan of a patient, determine a treatment plan involving delivery of energy from a plurality of gantry positions relative to the patient, and provide control data associated with the treatment plan to the proton beam system, the control data configured to control the proton beam system in performing the treatment plan. In some examples, each field specified by the treatment plan can be associated with a beam configuration targeting a planned target volume, such that each spot path of the beam configuration is separated from at least one other spot path of the beam configuration by a distance that satisfies a threshold distance.
