To evaluate the magnitude and resulting impact of rotational error in rectal cancer patients, and to investigate the feasibility of planning target volume (PTV) margin reduction to improve organs‐at‐risk (OAR) sparing. Abstract Introduction The magnitude and impact of rotational error is unclear in rectal cancer radiation therapy.

Dosimetrie eines Blutbestrahlungsgerätes [PDF]
Blood and blood products are irradiated to avoid the graft-versus-host disease (GVHD) in immunosuppressed patients and to destroy tumor cells during the intra-operative autotransfusion in tumor surgery. For that purpose more and more dedicated gamma irradiators are used.

Evaluation of the effect of metal stents on dose perturbation in the carbon beam irradiation field
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

Acute toxicity and patient‐reported outcomes in anal canal cancer: results of a pilot study
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 ...

The Multigaussian method: a new approach to multichannel radiochromic film dosimetry [PDF]
The main objective of multichannel radiochromic film dosimetry methods is to correct, or at least mitigate, spatial heterogeneities in the film-scanner response, especially variations in the active layer thickness. To this end, films can also be scanned prior to irradiation.

Calibration strategies for use of the nanoDot OSLD in CT applications. [PDF]
Aluminum oxide based optically stimulated luminescent dosimeters (OSLD) have been recognized as a useful dosimeter for measuring CT dose, particularly for patient dose measurements.

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

Pencil‐beam scanning proton therapy for the treatment of glomus jugulare tumours
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.

Three‐dimensional printer use in the Australian and New Zealand radiation therapy setting
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.
