BACKGROUND The purpose of this study is to report our experience using radiofrequency-assisted liposuction (RFAL) for neck and face contouring. This article details the operative technique, selection, complications, third-party surgeon appraisal, and patient satisfaction survey. METHODS From November 2009 to November 2013, 55 patients who underwent RFAL treatment were enrolled in the study. P...

Abstract Purpose To investigate the impact of computed tomography (CT) image acquisition and reconstruction parameters, including slice thickness, pixel size, dose, on automatic contouring algorithms. Methods Eleven scans from patients with head‐and‐neck cancer were reconstructed varying thicknesses sizes. CT dose was varied by adding noise using low‐dose simulation software. The these imaging ...

This paper evaluates the effectiveness of an interactive, three-dimensional image segmentation technique that relies on watersheds. This paper presents two user-based case studies, which include two different groups of domain experts. Subjects manipulate a graphics-based front end to a hierarchy of segmented regions generated from a watershed segmentation algorithm, which is implemented in the ...

PURPOSE To analyze the error in contouring the brainstem for patients with head and neck cancer who underwent radiotherapy (RT) based on computed tomography (CT) and magnetic resonance (MR) images. METHODS 20 patients with brain tumor and 17 patients with nasopharyngeal cancer (NPC) were randomly selected. Each patient underwent MR and CT scanning. For each patient, one observer contoured the...

'The multidisciplinary approach: expanding treatment horizons for head and neck cancer' was the major theme of the Indo Global Summit on Head and Neck Oncology (IGSHNO 2017-BMCON-IV). The meeting, held in Jaipur (Rajasthan, India) from 24 to 26 February 2017, assembled 600 participants from India and worldwide. It was organised by the Bhagwan Mahaveer Cancer Hospital and Research Centre (BMCHRC...

BACKGROUND Preferred techniques for rejuvenation and contouring of the neck region have evolved over the past 40 years. A slender neckline is recognized as an attractive feature of youth, whereas aging of the lower face often includes ptosis of the soft tissues of the chin and banding or cording of the muscles of the anterior and lateral neck. Aesthetic rejuvenation of the face and neck involve...

Various commercial auto-contouring solutions have emerged over past few years to address labor-intensiveness, and inter- intra-operator variabilities issues of traditional manual anatomy contouring for head neck (H&N) radiation therapy (RT). The purpose this study is compare the clinical performances between RaySearch Laboratories deep learning (DL) atlas-based tools organs at risk (OARs) s...

Radiotherapy planning requires accurate delineations of the critical structures. To avoid manual contouring, atlas-based segmentation can be used to get automatic delineations. However, the results strongly depend on the chosen atlas, especially for the head and neck region where the anatomical variability is high. To address this problem, atlases adapted to the patient's anatomy may allow for ...
