Purpose To develop a tumor tracking method based on a surrogate-driven motion model,
which provides noninvasive dynamic localization of extracranial targets for the …

Purpose Lung stereotactic ablative body radiotherapy (SABR) is a radiation therapy success
story with level 1 evidence demonstrating its efficacy. To provide real‐time respiratory …

The ability to monitor tumor motion without implanted markers can potentially enable broad
access to more accurate and precise lung radiotherapy. A major challenge is that kilovoltage …

Abstract Introduction Digitally reconstructed radiographs (DRRs) represent valuable patient-
specific pre-treatment training data for tumor tracking algorithms. However, using current …

Purpose On‐treatment kV images have been used in tracking patient motion. One challenge
of markerless motion tracking in paraspinal SBRT is the reduced contrast when the X‐ray …

Purpose To evaluate markerless tumor tracking (MTT) using fast‐kV switching dual‐energy
(DE) fluoroscopy on a bench top system. Methods Fast‐kV switching DE fluoroscopy was …

Purpose:(1) To validate retrospective markerless tracking software for small lung tumors by
comparing tracked motion in 4‐dimensional planning computed tomography (4DCT) derived …

Visualization of anatomy in real time is of critical importance for motion management in lung
cancer radiotherapy. To achieve real-time, and high-contrast in-treatment imaging, we …

The ability to monitor tumor motion without implanted markers is clinically advantageous for
lung image-guided radiotherapy (IGRT). Existing markerless tracking methods often suffer …

Lung tumors treated in breath-hold are subject to inter-and intra-breath-hold variations,
which makes tumor position monitoring during each breath-hold important. A markerless …
