Article Synopsis
- Treatment Planning Systems (TPS) are evaluated for their effectiveness in correcting distortions in Magnetic Resonance (MR) images using a virtual phantom and Control Points (CPs).
- The study involved creating distorted MR images and applying TPS, with findings showing that distortion caused median deviations of 1.8 mm, which were reduced to 0.6 mm after correction.
- Structural Similarity Metric (SSIM) tests indicated significant improvements in image quality, with the TPS successfully reducing distortions to levels acceptable for radiosurgery.
Purpose: To optimize PTV margins for single isocenter multiple metastases stereotactic radiosurgery through a genetic algorithm (GA) that determines the maximum effective displacement of each target (GTV) due to rotations.
Method: 10 plans were optimized. The plans were created with Elements Multiple Mets™ (Brainlab AG, Munchen, Germany) from a predefined template.
A method to enhance 2D ion chamber array patient specific quality assurance for IMRT.

Gamma index comparison has been established as a method for patient specific quality assurance in IMRT. Detector arrays can replace radiographic film systems to record 2D dose distributions and fulfill quality assurance requirements. These electronic devices present spatial resolution disadvantages with respect to films.
