To investigate the effect of bolus–surface air gap on surface dose calculation for a clinical 6 MV photon beam.

We present advancements of single-molecule biodosimetry to measure radiation-induced DNA damage from α-emitting 225Ac. These results will be compared to β-emitting radionuclides to assess relative biological effectiveness (RBE) for radionuclide therapies.

Small metallic objects such as titanium and tantalum surgical clips are frequently present in clinical treatment planning images. Because these objects produce streak artifacts in planning CT images and may lie within the beam path, there is concern that they...

The Liberty Vision Y-90 ophthalmic applicator (LV-90) is an FDA approved HDR source for episcleral brachytherapy to treat ocular tumors and benign growths. It is an attractive option for patients because it does not require episcleral sutures, muscle relocati...

With advances in Targeted Alpha Therapy (TAT) preclinical and clinical research, the importance for accurate and traceable dosimetry with sub-organ resolution becomes critical. Current limitations in verifying imaging resolution and activity quantification hi...

Accurate absorbed dose determination for alpha emitting sources remains challenging due to short particle ranges and sensitivity to source geometry. This work presents a practical framework for direct absorbed dose to water measurements from a plated 241Am so...
