Background Adjuvant endocrine therapy (ET) is standard of care in women with hormone receptor-positive (HR+) breast cancer (BC) with the goal to reduce recurrence. However, early discontinuation of ET occurs in 30-40% of women, largely attributable t

PURPOSE Automatic segmentation offers many benefits for radiotherapy treatment planning; however, the lack of publicly available benchmark datasets limits the clinical use of automatic segmentation. In this work, we present a well-curated computed to

Purpose To automatically segment the diaphragm on individual lung cone-beam CT projection images, to enable real-time tracking of lung tumors using kilovoltage imaging. Methods The deep neural network Mask R-CNN was trained on 3500 raw cone-beam CT p

Purpose The use of magnetic resonance imaging (MRI) in radiotherapy treatment planning has rapidly increased due to its ability to evaluate patient's anatomy without the use of ionizing radiation and due to its high soft tissue contrast. For these re

Treatment uncertainties in radiotherapy are either systematic or random. This study evaluates the sensitivity of fractionated intensity-modulated proton therapy (IMPT) lung treatments to systematic and random setup uncertainties. Treatments in which

Purpose: Motion interplay can affect the tumor dose in scanned proton beam therapy. This study assesses the ability of rescanning and gating to mitigate interplay effects during lung treatments. Methods: The treatments of five lung cancer patients [4

Objective: We introduce descriptor-based segmentation that extends existing patch-based methods by combining intensities, features, and location information. Since it is unclear which image features are best suited for patch selection, we perform a b

Extraction and representation of contours are challenging problems and are crucial for many image processing applications. In this study, given a membership function that returns the score of a point belonging to a contour, we propose a method for co

Aim To describe and evaluate a community-based musculoskeletal service, commissioned by National Health Services North East Essex Primary Care Trust (PCT), in terms of patient-reported outcomes and satisfaction. Background Persistent musculoskeletal
