Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose/objectives Recent technological advancements have increased efficiency for clinical deliverability of online‐adaptive‐radiotherapy (oART). Previous cone‐beam‐computed‐tomography (CBCT) generations lacked the ability to provide reliable Hounsfield‐units (HU), thus requiring oART workflows to rely on synthetic‐CT (sCT) images derived ...

Acute toxicity and patient‐reported outcomes in anal canal cancer: results of a pilot study
Journal of Medical Radiation Sciences, Volume 69, Issue 4, Page 484-491, December 2022., 2022 After reaching their maximum at the end of treatment, the majority of toxicity and patient reported outcomes (PROs) items approached baseline levels by 3 months post treatment. The results of this study suggest that PROs are an important complementary tool to Common Terminology Criteria for Adverse Effects (CTCAE) and provide greater understanding of ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Palliative radiotherapy comprises a significant portion of the radiation treatment workload. Volumetric‐modulated arc therapy (VMAT) improves dose conformity and, in conjunction with flattening filter free (FFF) delivery, can decrease treatment times, both of which are desirable in a population with a high probability of retreatment ...

Pencil‐beam scanning proton therapy for the treatment of glomus jugulare tumours
Journal of Medical Radiation Sciences, Volume 69, Issue 4, Page 456-462, December 2022., 2022 The rare locally destructive glomus jugulare tumours could be treated using pencil‐beam scanning proton therapy (an alternative to surgery). Proton therapy provides good local control and acceptable toxicity. This paper reports treatment outcomes, acute and early late toxicities of 12 patients with glomus jugulare tumours.

Evaluation of the effect of metal stents on dose perturbation in the carbon beam irradiation field
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Propose Carbon ion therapy is indicated for cases in which stents have been inserted, such as bile ducts, but the effect of metal stents on carbon ion therapy is unclear. In this study, the dose perturbation of carbon ion therapy caused by metallic bile duct stents was evaluated by dosimetry. Materials and methods Five different types of metal

Three‐dimensional printer use in the Australian and New Zealand radiation therapy setting
Journal of Medical Radiation Sciences, Volume 69, Issue 4, Page 492-501, December 2022., 2022 This cross‐sectional survey aimed to established a baseline of 3D printer and product use within Australian and New Zealand radiation therapy departments. Survey response rate was 100% with 22.3% of departments reporting ownership of one or more 3D printers, and 34 departments purchasing 3D printed products from an external provider.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose The dual‐layer multileaf collimator (MLC) in Halcyon adds complexities to the dose calculation process owing to the variability of dosimetric characteristics with leaf motion. Recently, an enhanced leaf model (ELM) was developed to refine the MLC model in the Eclipse treatment planning system. This study investigates the performance of

Closing the gap in plan quality: Leveraging deep‐learning dose prediction for adaptive radiotherapy
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Balancing quality and efficiency has been a challenge for online adaptive therapy. Most systems start the online re‐optimization with the original planning goals. While some systems allow planners to modify the planning goals, achieving a high‐quality plan within time constraints remains a common barrier.
