Abstract

An image-guided radiation therapy apparatus comprises: a high-energy ray source configured for radiation therapy of an object; and a KV ray source, a first and second PET detectors, and a CT detector for KV CT and PET imaging for guiding the radiation therapy. The KV ray source is placed on, or at an inner or outer side of the first PET detector; the second PET detector and the CT detector are configured to receive the KV ray to perform KV CT imaging; the PET detectors are further configured to receive gamma ray emitted by the object to perform PET imaging.
