A multi-institutional journal club (MIJC) was introduced by the AAPM’s Working Group on Multi-Institutional Journal Clubs for Residency Programs (WGJCRP) in 2021. As of 2022, 40% of therapy programs were participating. The MIJC program was intended to connect...

Proton dose calculation is sensitive to the metal wires, which are placed on the patient's skin during CT simulation to precisely outline the location of surgical scars and the intended radiation treatment field borders. In order to avoid the dose uncertainti...

The bladder is kept full during prostate proton therapy to push the small and large intestines out of the radiation field and maintain a consistent position for the bladder and nearby pelvic organs. However, it is a challenge to keep a regular bladder volume...

In vivo dosimetry is essential for treatment verification and patient safety. Although commercial radiochromic film systems are established for photons, proton therapy adds complexity because film response is energy dependent and clinical beams are typically...

Proton pencil beam scanning (PBS) offers excellent dose conformity but remains limited by delivery inefficiency associated with energy layer switching time. A programmable energy modulation filter (PEMF) was developed to enable single-energy proton PBS delive...

Breast patients treated with intensity-modulated proton therapy (IMPT) often experience more severe skin dose toxicity compared to those with photon 3DCRT. Here we quantitatively estimated the LET-dependent RBE (LET-RBE) vs clinically used constant RBE=1.1 fo...
