Prediction of mandibular ORN incidence from 3D radiation dose distribution maps using deep learning [PDF]
arXiv, 2021 Background. Absorbed radiation dose to the mandible is an important risk factor in the development of mandibular osteoradionecrosis (ORN) in head and neck cancer (HNC) patients treated with radiotherapy (RT). The prediction of mandibular ORN may not only guide the RT treatment planning optimisation process but also identify which patients would benefit

Comparison of Deep Learning Segmentation and Multigrader-annotated Mandibular Canals of Multicenter CBCT scans [PDF]
arXiv, 2022 Deep learning approach has been demonstrated to automatically segment the bilateral mandibular canals from CBCT scans, yet systematic studies of its clinical and technical validation are scarce. To validate the mandibular canal localization accuracy of a deep learning system (DLS) we trained it with 982 CBCT scans and evaluated using 150 scans of five ...

The effect of stiffness and hole size on nipple compression in infant suckling
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 1, Page 92-100, January 1, 2023., 2023 Sensory input from the nipple has been shown to affect infant feeding across commercially available nipples that also vary shape and size. Here, we isolated two specific nipple properties, stiffness, and hole size, in otherwise uniform nipples, while bottle feeding infant pigs.

Journal of Morphology, Volume 284, Issue 1, January 2023., 2023 We document in detail the morphology of adults of the beaver beetle Platypsyllus castoris with modern techniques, and interpret evolutionary changes linked with the specific life style of the beetle in the fur of the beaver. Platypsyllus displays numerous structural specializations which ensure mechanical stabilization, firm anchorage on the host, and ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background Volumetric modulated arc therapy (VMAT) requires an accurate patient‐specific quality assurance (PSQA) program. In clinical practice, this is usually performed using the γ‐index and the two‐dimensional gamma passing rate (2D %GP). A three‐dimensional (3D) index incorporating the patient anatomy could be more useful for the 3D dose ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Current radiotherapy practices rely on manual contouring of CT scans, which is time‐consuming, prone to variability, and requires highly trained experts. There is a need for more efficient and consistent contouring methods. This study evaluated the performance of the Varian Ethos AI auto‐contouring tool to assess its potential integration into

Extending the boundaries of carotid body tumor excision with a maxillofacial surgeon
Indian Journal of Vascular and Endovascular Surgery, 2019 Introduction: Carotid body tumor (CBT) excision at times requires a multidisciplinary approach. Requests for mandibular swing or mandibular subluxation were received by the department of dental and oral surgery to aid in CBT excision.

Automatic Ultrasound Image Segmentation of Supraclavicular Nerve Using Dilated U-Net Deep Learning Architecture [PDF]
arXiv, 2022 Automated object recognition in medical images can facilitate medical diagnosis and treatment. In this paper, we automatically segmented supraclavicular nerves in ultrasound images to assist in injecting peripheral nerve blocks. Nerve blocks are generally used for pain treatment after surgery, where ultrasound guidance is used to inject local ...
