3D Fusion between Fluoroscopy Angiograms and SPECT Myocardial Perfusion Images to Guide Percutaneous Coronary Intervention [PDF]
arXiv, 2020 Background. Percutaneous coronary intervention(PCI) in stable coronary artery disease(CAD) is commonly triggered by abnormal myocardial perfusion imaging(MPI). However, due to the possibilities of multivessel disease and variability of coronary artery perfusion distribution, opportunity exists to better align anatomic stenosis with perfusion ...

Bevel-Tip Needle Deflection Modeling, Simulation, and Validation in Multi-Layer Tissues [PDF]
arXiv, 2023 Percutaneous needle insertions are commonly performed for diagnostic and therapeutic purposes as an effective alternative to more invasive surgical procedures. However, the outcome of needle-based approaches relies heavily on the accuracy of needle placement, which remains a challenge even with robot assistance and medical imaging guidance due to ...

Computer-aided hepatic tumour ablation [PDF]
Lecture notes in computer science (LNCS) 2208 (2001) 1145-1146, 2006 Surgical resection of hepatic tumours is not always possible. Alternative techniques consist in locally using chemical or physical agents to destroy the tumour and this may be performed percutaneously. It requires a precise localisation of the tumour placement during ablation.

Controlling the Error on Target Motion through Real-time Mesh Adaptation: Applications to Deep Brain Stimulation [PDF]
, 2017 We present an error-controlled mesh refinement procedure for needle insertion simulation and apply it to the simulation of electrode implantation for deep brain stimulation, including brain shift. Our approach enables to control the error in the computation of the displacement and stress fields around the needle tip and needle shaft by suitably ...

Untangling biliary reconstruction in liver transplants for primary sclerosing cholangitis
World Journal of Surgery, Volume 48, Issue 9, Page 2253-2261, September 2024.Abstract Background Biliary reconstruction technique during liver transplant (LT) for primary sclerosing cholangitis (PSC) remains controversial. This study aimed to evaluate the incidence of biliary complications in patients with PSC having a duct‐to‐duct (DD) anastomosis or Roux‐en‐Y hepaticojejunostomy (HJ).

The CNN-based Coronary Occlusion Site Localization with Effective Preprocessing Method [PDF]
, 2019 The Coronary Artery Occlusion (CAO) acutely comes to human, and it highly threats the human's life. When CAO detected, Percutaneous Coronary Intervention (PCI) should be conducted timely. Before PCI, localizing the CAO is needed firstly, because the heart is covered with various arteries.

Hepatobiliary scintigraphy with SPET in the diagnosis of bronchobiliary fistula due to a hydatid cyst [PDF]
, 2015 In this report, we present the application of hepatobiliary scintigraphy using Tc-99m mebrofenin in the diagnosis of bronchobiliary fistula caused by a liver hydatid cyst, which penetrated the diaphragm. Hepatobiliary scintigraphy noticeably depicted the
