Abstract Imaging biomarkers can assess disease progression or prognoses and are valuable tools to help guide interventions. Particularly in lung imaging, biomarkers present an opportunity to extract regional information that is more robust to the pat

Vessel segmentation in the lung is an ongoing challenge. While many methods have been able to successfully identify vessels in normal, healthy, lungs, these methods struggle in the presence of abnormalities. Following radiotherapy, these methods tend

Recent functional lung imaging studies have presented evidence of an “indirect effect” on perfusion damage, where regions that are unirradiated or lowly irradiated but that are supplied by highly irradiated regions observe perfusion damage post-r

Microwave (MW) ablation and stereotactic body radiation therapy (SBRT) have potentially complementary advantages and limitations for treating inoperable renal cell carcinoma (RCC). Combining SBRT and MWA may optimize tumor control and toxicity for pa

Kilovoltage radiographs are acquired during motion‐synchronized treatments on Radixact to localize the tumor during the treatment. Several previous publications have provided estimates of patient dose from these planar radiographs. However, a recen
