描述
Inclusion Criteria:
- Age ≥ 18
- Any patient undergoing radiation therapy for a cancer lesion in the abdomen in close proximity to OARs that is hypothesized to have differential displacement on inhale and exhale breath hold CT scans of the OAR relative to the tumor.
- Patients need at least 3 fractions of RT
- Critical OARs are within 2 cm of luminal GI structures, chest wall, or previous radiation fields
- Able to receive and understand verbal and written information regarding study and able to give written informed consent
Exclusion Criteria:
- Inability to perform inhale or exhale breath holds during standard workflow CT simulation evaluation

实验性的:影像学

Obtain inhale and exhale breath hold images planned to split radiation delivery between inhale and exhale breath hold phases. For radiotherapy courses with an odd number of fractions, the phase of breath hold with higher reproducibility or anatomic advantage will be used for the additional fraction of radiotherapy. If during the treatment planning the investigators determine that the patients will benefit from the multiple breath holds technique, the patients will be treated using the composite breath hold plan. Additional one or two cone beam CTs will be obtained on treatment days for all patients using the inhale and exhale breath hold technique. |
