Summary
Brief summary (as posted)
Cone beam computed tomography (CBCT) images are routinely used in radiation treatment delivery workflows to align patients with the treatment beam. Conventional CBCT image quality is sufficient for this task but not good enough for other radiotherapy-related tasks, such as contouring anatomical structures and calculating radiation dose distributions. HyperSight is a new CBCT imaging system manufactured by Varian Medical Systems. The purpose of this study is to evaluate the integration of the HyperSight imaging system with Varian's TrueBeam radiotherapy system, a linear accelerator with a C-arm gantry that rotates about the patient to delivery radiation to the target malignancy. HyperSight CBCT images will be acquired prospectively from patients who are receiving radiation treatment. The HyperSight/TrueBeam system will be used for imaging only; patients receive their radiation treatment on cleared devices and no aspect of their treatment is affected by participation in the study. HyperSight images collected during the study will be evaluated for quality and utility and compared to conventional CBCT images as well as fan beam CT images used for treatment planning.

Show eligibility criteria text
Inclusion Criteria: 1. Patient is scheduled to receive radiation therapy to one of the following anatomical sites: head and neck/brain, thorax, abdomen, pelvis. 2. Patient is at least 18 years of age. 3. If the patient will be receiving IV contrast on study, patient must have adequate renal function as defined by an estimated glomerular filtration rate (eGFR) of \>30. Note: if no IV contrast will be administered on study, patient may enroll without creatinine level documented. Contrast eligibility will be determined as per Appendix A. 4. If the patient is a woman of childbearing potential, patient must have a negative pregnancy test within 30 days of enrollment and prior to any study imaging. Contraceptive use is not an adequate documentation of no chance of pregnancy. Exclusion Criteria: 1. Patient is unwilling or unable to sign an IRB-approved written informed consent document. 2. Patient is part of a vulnerable population (per ISO 14155:2020, "individuals who are unable to fully understand all aspects of the investigation that are relevant to the decision to participate, or who could be manipulated or unduly influenced as a result of a compromised position, expectation of benefits or fear of retaliatory response").
