AI Technical Summary

Technical Problem

Current image-guided radiation therapy systems face challenges in achieving precise and efficient alignment of therapeutic beams with target regions due to limitations in real-time tracking and integration of imaging and treatment assemblies, which can affect the accuracy and efficiency of radiation therapy.

Method used

The system integrates a first detection assembly, such as a PET detector, and an imaging source, like a CT or DR source, on a rotatable part, allowing for independent movement and positioning between different configurations to ensure real-time guidance and precise alignment of therapeutic beams without interfering with imaging performance.

Benefits of technology

This integration enhances the precision and efficiency of adaptive radiotherapy by enabling real-time tracking and positioning of therapeutic beams, improving the accuracy of radiation delivery while maintaining high imaging quality and reducing space requirements.

Abstract

Embodiments of the present disclosure provide an image-guided radiation therapy system and a method thereof. The system includes a first detection assembly, at least one imaging source, and a radiation source. The first detection assembly may be configured to determine a first image of a target region of an object by receiving a photon signal generated by a radioactive isotope within the object. The at least one imaging source may be configured to determine a second image by emitting an imaging beam to the target region of the object. The radiation source may be configured to emit a therapeutic beam to the target region of the object. The first detection assembly and the at least one imaging source may be mounted on a first rotatable part, the radiation source may be mounted on a second rotatable part, and the first rotatable part and the second rotatable part may be coaxially and coplanarly arranged. The first rotatable part may be configured to be rotatable independently relative to the second rotatable part.
