Introduction: The integration of digital technology in healthcare, particularly for patient education and experience, is rapidly advancing. This pilot study examined the feasibility of an interactive panoramic virtual tour for improving patient experiences in an external beam radiation therapy (RT) setting at a smaller center.

Methods: A virtual tour of the RT department was developed using specialized software and 360-degree 8K camera.

This study evaluates alternative shielding materials to lead for protecting the scalp and nails during total skin electron irradiation. We tested a silicone helmet, tungsten-doped silicone mittens, and planar aluminum and copper shields. The helmet and mittens were created using 3D modeling software and fused filament fabrication printing, while the planar shields were machined and assembled with printed hardware.

Article Synopsis
  • Researchers developed a new 3D-printed phantom called OneIso to improve quality-assurance procedures for brain radiosurgery, especially in multi-target treatments.
  • The phantom allows for multiple testing methods, including Winston-Lutz tests and dose measurements, without needing to relocate the phantom itself, enhancing precision and accuracy.
  • Validation across eight institutions showed that dose verification results using OneIso were consistently within 3% agreement, demonstrating the effectiveness of this integrated QA approach.

Background And Purpose: Concerns over chest wall toxicity has led to debates on treating tumors adjacent to the chest wall with single-fraction stereotactic ablative radiotherapy (SABR). We performed a secondary analysis of patients treated on the prospective iSABR trial to determine the incidence and grade of chest wall pain and modeled dose-response to guide radiation planning and estimate risk.

Materials And Methods: This analysis included 99 tumors in 92 patients that were treated with 25 Gy in one fraction on the iSABR trial which individualized dose by tumor size and location.

Purpose: A well-known limitation of multi-leaf collimators is that they cannot easily form island blocks. This can be important in mantle region therapy. Cerrobend photon blocks, currently used for supplementary shielding, are labor-intensive and error-prone.
