Non fluoroscopic ablation of different arrhythmic structures in an electrophysiology unit. Assessment of efficiency and security.

Background: Electroanatomical mapping systems (EMS) reduce fluoroscopy dose for the ablation. Higher costs and longer procedure times are the drawbacks associated with EMS. Our objective was to validate the efficiency of the EMS.

Ionizing Radiation Measurement Solution in a Hospital Environment.

Ionizing radiation is one of the main risks affecting healthcare workers and patients worldwide. Special attention has to be paid to medical staff in the vicinity of radiological equipment or patients undergoing radioisotope procedures. To measure radiation values, traditional area meters are strategically placed in hospitals and personal dosimeters are worn by workers.

Volumetric-modulated Arc Therapy Lung Stereotactic Body Radiation Therapy Dosimetric Quality Assurance: A Comparison between Radiochromic Film and Chamber Array.

Introduction: The aim of this work is to verify the use of radiochromic film in the quality assurance (QA) of volumetric-modulated arc therapy (VMAT) lung stereotactic body radiation therapy (SBRT) plans and compare the results with those obtained using an ion chamber array.

Materials And Methods: QA was performed for 14 plans using a two-dimensional-array seven29 and EBT3 film. Dose values per session ranged between 7.

Results of 1 year of clinical experience with independent dose calculation software for VMAT fields.

It is widely accepted that a redundant independent dose calculation (RIDC) must be included in any treatment planning verification procedure. Specifically, volumetric modulated arc therapy (VMAT) technique implies a comprehensive quality assurance (QA) program in which RIDC should be included. In this paper, the results obtained in 1 year of clinical experience are presented.
