Systems and methods for image-guided radiotherapy using dual robot architecture

Abstract

A system for coordinating radiation therapy and imaging processes includes a radiation therapy system an radiation source mounted on a robotically-controlled system to move the radiation source abouta subject to direct radiation to a target area in the subject according to a treatment plan. The system also includes an imaging system configured to acquire imaging data from a subject. The imaging system and the radiation therapy system are independently movable. The system also includes a coordination system configured to coordinate operation of the imaging system to acquire the imaging data from the subject during movement of the radiation source about the subject according to the treatment plan to avoid collisions of the radiation therapy system with the imaging system.

[0003] A Note About Federally Funded Research [0004] This invention was made with Government support under award CA183390 from the National Institutes of Health. The government has certain rights in this invention. Background technique [0005] The present disclosure generally relates to image-guided radiation therapy systems and methods. [0006] Conventional external beam radiation therapy, also known as "teletherapy," is typically delivered by directing a linear accelerator ("LINAC") to produce a beam of ionizing radiation that irradiates a defined target volume of a subject. A radiation beam is a single radiation beam delivered to the ...

Problems solved by technology

Although these sources can provide real-time 2D radiographic images for treatment alignment, they cannot be used to generate CT images of subjects

Furthermore, 2D radiographic images lack volumetric information and cannot image tumors using only soft tissue contrast, which is highly desirable in many cases

On the other hand, CT imaging systems are based on C-arm and ring gantry systems to image and place subjects, and CT imaging systems are limited in range of motion and treatment flexibility
