Commissioning of horizontal Leipzig applicators in HDR typically includes determination of the effective distal source position and output verification using a suitable chamber. In addition to those methods, we previously described an end-to-end testing proce...

Film is typically read using a flatbed scanner, but these scanners are prone to Type A errors (orientation, placement, etc.). We compare dose calibration of EBT4 radiochromic film from 6MV exposures using a flatbed film scanner and a single-point transmission...

To develop and evaluate an end-to-end testing procedure for catheter-based prostate HDR treatments using in-house fabricated 16 mm EBT4 radiochromic film, refining a previously described OSLD-based methodology.

In-vivo dosimetry requires compact dosimeters suitable for patient placement, with multiple detectors often deployed simultaneously for spatial sampling. The 2023 nanoDot OSLD recall left many clinics without accessible, low-cost alternatives. Our purpose is...
