Stereotactic arrhythmia radioablation for refractory ventricular tachycardia: A narrative review and pooled analysis of clinical outcomes and treatment delivery approaches. [PDF]

J Appl Clin Med Phys
Abstract Purpose Stereotactic arrhythmia radioablation (STAR) has emerged as a noninvasive salvage therapy for refractory ventricular tachycardia (VT), particularly in patients ineligible for catheter ablation (CA). This narrative review and pooled analysis evaluates STAR's efficacy, safety, and technical characteristics, integrating evidence from ...

Assessment of rotational dose perturbations in SBRT: A radiomic-dosiomic predictive model based on the structural similarity index measure. [PDF]

J Appl Clin Med Phys
Abstract Background Stereotactic body radiation therapy (SBRT) delivers ablative doses with high precision but is sensitive to target motion, especially rotational errors. Conventional dose metrics (dose difference (DD), distance‐to‐agreement (DTA), gamma index) show limited sensitivity.

Point Dosimetry in Patient-specific Quality Assurance of a Robotic Radiosurgery System Using a Scintillation Detector [PDF]

Journal of Medical Physics
Purpose: Patient-specific quality assurance (QA) for CyberKnife is typically performed using micro ionization chambers and film dosimetry. However, micro ionization chambers tend to underestimate dose measurements in small radiation fields.
