Surface guided ring gantry radiotherapy in deep inspiration breath hold for breast cancer patients.

Purpose: This study investigated the use of surface guided radiotherapy (SGRT) in combination with a tomotherapy treatment mode using discrete delivery angles for deep inspiration breath hold (DIBH) treatments of breast cancer (bc). We aimed to assess the feasibility and dosimetric advantages of this approach.

Materials And Methods: We evaluated camera occlusion in the Radixact treatment system bore and the stability of DIBH signals during couch movement.

Dynamic anthropomorphic thorax phantom for quality assurance of motion management in radiotherapy.

Background And Purpose: Motion management techniques are important to spare the healthy tissue adequately. However, they are complex and need dedicated quality assurance. The aim of this study was to create a dynamic phantom designed for quality assurance and to replicate a patient's size, anatomy, and tissue density.

Abdominal compression as motion management for stereotactic radiotherapy of ventricular tachycardia.

Background And Purpose: Stereotactic body radiotherapy (SBRT) has emerged as a promising treatment for patients with ventricular tachycardia (VT) who do not respond to standard treatments. However, the management of respiratory motion during treatment remains a challenge. This study aimed to investigate the effect of abdominal compression (AC) on respiratory induced motion in the heart.
