摘要： An imaging apparatus includes: a first scintillator layer configured to provide first image signals with a first quantum efficiency and a first spatial resolution; a second scintillator layer configured to provide second image signals with a second quantum efficiency and a second spatial resolution, wherein the first quantum efficiency is lower than the second quantum efficiency, but the first spatial resolution is higher than the second spatial resolution; and an image combiner configured to combine the first image signals and the second image signals.

摘要： A method of radiation therapy comprises, while a gantry of a radiation therapy system rotates continuously in a first direction through a treatment arc from a first treatment delivery position to a second treatment delivery position, causing an imaging X-ray source mounted on the gantry to direct X-rays through a target volume and receiving a set of X-ray projection images from an X-ray imager mounted on the gantry; determining a current location of the target volume based on the set of X-ray projection images; and while the gantry to continues to rotate to the second treatment delivery position, initiating delivery of a treatment beam of a treatment-delivering X-ray source mounted on the gantry to the target volume, and continuing to cause the gantry to rotate in the first direction from the second treatment delivery position to a third treatment delivery position.

摘要： A radiation therapy system is configured to enable imaging and treatment of a target volume during a single patient breath hold. The radiation system includes a rotating gantry on which are mounted a treatment-delivering X-ray source and multiple imaging X-ray sources and corresponding X-ray imaging devices. The multiple imaging X-ray sources and X-ray imaging devices enable the acquisition of volumetric image data for the target volume over a relatively short rotational arc, for example 30 degrees or less. Therefore, intra-fraction motion can be detected in near-real time, for example within about one second or less. The radiation therapy system can perform image guided radiation therapy (IGRT) that monitors intra-fraction motion using X-ray imaging. Detected anatomical variations can then either be compensated for, via patient repositioning and/or treatment modification, or the current treatment can be aborted.
