Systems and methods for real-time imaging

Abstract

Embodiments of the present disclosure are directed to a system for generating three-dimensional images of a target region of a patient. The system may include at least one computer system. The computer system may be configured to receive a plurality of non-parallel projection images of the target region of the patient, convert the plurality of non-parallel projection images into a non- spatial domain, reconstruct a three-dimensional image from the plurality of non- parallel projection images in the non-spatial domain, and convert the reconstructed three-dimensional image from the non-spatial domain to the spatial domain.

Description

[0001] related application [0002] This application claims priority to US Application Serial No. 15 / 357,193, filed November 21, 2016, the entire disclosure of which is incorporated herein by reference in its entirety. technical field [0003] Aspects of the present disclosure relate generally to radiation therapy systems, and in particular to methods and systems for real-time imaging and motion management for use with, for example, radiation therapy systems. Background technique [0004] Radiation therapy (also known as radiotherapy) may be used in the treatment of cancer or other conditions. Radiation therapy involves delivering prescribed doses of radiation to a targeted area of ​​a patient, for example, to a tumor or other cancerous tissue. The target area may be imaged prior to delivery of radiation therapy, and a treatment plan may be developed based on, for example, the size, location and / or orientation of the target and surrounding structures. Radiation can then b...

Problems solved by technology

Using a "cine CBCT" rather than a "cine projection" solution, it is possible to detect lower contrast targets where fiducials are usually not required, but again, the computing power required to perform such calculations may not be suitable for real-time applications
