Evaluation of the Minimum Segment Width and Fluence Smoothing Tools for Intensity-modulated Techniques in Monaco Treatment Planning System.

Purpose: This study aims to minimize monitor units (MUs) of intensity-modulated treatments in the Monaco treatment planning system while preserving plan quality by optimizing the "Minimum Segment Width" (MSW) and "Fluence Smoothing" parameters.

Materials And Methods: We retrospectively analyzed 30 prostate, 30 gynecological, 15 breast cancer, 10 head and neck tumor, 11 radiosurgery, and 10 hypo-fractionated plans. Original prostate plans employed "Fluence Smoothing" = and were reoptimized with , , and settings.

End-To-End Procedure For IORT in Brain Metastases and Film Dosimetry.

Purpose: The study is intended to perform an end-to-end test of the entire intraoperative process using cadaver heads. A simulation of tumor removal was performed, followed by irradiation of the bed and measurement of absorbed doses with radiochromic films.

Materials And Methods: Low-energy X-ray intraoperative radiotherapy (IORT) was used for irradiation.

Right lateral versus left lateral view for forearm coronary angiography. An operator radiation exposure and image quality study.

Objectives: The aim of this study was to analyze the operator radiation exposure (ORE) and the image quality in a coronary angiography (CA) of the standard left lateral view (LLV) and compare it with an alternative right lateral view (RLV).

Background: Interventional cardiologists are exposed to high doses of scatter radiation, especially in angulated projections.

Methods: We prospectively included consecutive patients who underwent diagnostic CA.
