Use of a virtual phantom to assess the capability of a treatment planning system to perform magnetic resonance image distortion correction.

Treatment Planning Systems (TPS) offer algorithms for distortion correction (DC) of Magnetic Resonance (MR) images, whose performances demand proper evaluation. This work develops a procedure using a virtual phantom to quantitatively assess a TPS DC algorithm. Variations of the digital Brainweb MR study were created by introducing known distortions and Control Points (CPs).

Long-term quality of life in patients with bariatric surgery evaluated with BAROS.

Unlabelled: Quality of life (QoL) significantly improves in the short term after bariatric surgery (BS). However, evidence on the long-term QoL of patients with BS is limited.

Aim: To analyze the long-term QoL of patients who underwent Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG).

Knowledge-Based Volumetric Modulated Arc Therapy Treatment Planning for Breast Cancer.

Purpose: To create and to validate knowledge-based volumetric modulated arc therapy (VMAT) models for breast cancer treatments without lymph node irradiation.

Materials And Methods: One hundred VMAT-based breast plans (manual plans [MP]) were selected to create two knowledge-based VMAT models (breast left and breast right) using RapidPlan™. The plans were generated on Eclipse v15.
