Self-Supervised Surgical Instrument 3D Reconstruction from a Single Camera Image [PDF]
arXiv, 2022 Surgical instrument tracking is an active research area that can provide surgeons feedback about the location of their tools relative to anatomy. Recent tracking methods are mainly divided into two parts: segmentation and object detection. However, both can only predict 2D information, which is limiting for application to real-world surgery.

A novel surgical procedure for papilla reconstruction using platelet rich fibrin
Contemporary Clinical Dentistry, 2012 Loss of interdental papilla predisposes to phonetic, functional, and esthetic problem. Surgical techniques are manifold, but are challenging and very unpredictable. The purpose of this case report is to present the use of platelet rich fibrin (PRF) in the reconstruction of papilla in the maxiallry anterior region of a forty year old woman who presented

FEBS Open Bio, EarlyView.The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in

FEBS Open Bio, EarlyView.In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

New classification of hypertrophy of the labia minora and correlation with indicated surgical techniques [PDF]
Revista Brasileira de Cirurgia Plástica, 2018 INTRODUCTION: Nymphoplasty or labioplasty is the most common genital plastic surgery. The objective of labioplasty is to correct hypertrophy of the labia minora and clitoral prepuce, removing excess tissue without affecting their function of protecting ...

Improving Surgical Training Phantoms by Hyperrealism: Deep Unpaired Image-to-Image Translation from Real Surgeries [PDF]
, 2018 Current `dry lab' surgical phantom simulators are a valuable tool for surgeons which allows them to improve their dexterity and skill with surgical instruments. These phantoms mimic the haptic and shape of organs of interest, but lack a realistic visual appearance. In this work, we present an innovative application in which representations learned from

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study aims to develop a CycleGAN based denoising model to enhance the quality of low‐dose PET (LDPET) images, making them as close as possible to standard‐dose PET (SDPET) images. Methods Using a Philips Vereos PET/CT system, whole‐body PET images of fluorine‐18 fluorodeoxyglucose (18F‐FDG) were acquired from 37 patients to ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Histotripsy is a focal tumor therapy that utilizes focused ultrasound (US) to mechanically destroy tissue. To overcome visualization limitations of diagnostic US‐guidance, C‐arm cone beam CT (CBCT)‐guided histotripsy is being developed, for which a mobile C‐arm could increase accessibility. CBCT‐guided histotripsy uses a phantom with a
