Soft‐tissue target motion is one of the main concerns in high‐precision radiation therapy. Cone beam computed tomography (CBCT) has been developed recently to image soft‐tissue targets in the treatment room for image‐guided radiation therapy. However, due to its relatively long image acquisition time the CBCT approach cannot provide images of the target at the instant of the treatment and thus is not adequate for imaging targets with intrafraction motion. In this work, a new concept for image‐guided radiation therapy— just‐in‐time tomography (JiTT) — is introduced. Differing from CBCT, JiTT takes much less time to generate the needed tomographical, beam's‐eye‐view images of the treatment target at the right moment to guide the radiation therapy treatment. A system to achieve JiTT is proposed and its feasibility is investigated. Research supported by Siemens.
