Electrode bending observed after stereotactic interventions is typically not accounted for in either computer-assisted planning algorithms, where straight trajectories are assumed, or in quality assessment, where only metrics related to entry and target points are reported. Our aim is to provide a fully automated and validated pipeline for the prediction of stereo-electroencephalography (SEEG) ele...... hiện toàn bộ
Intelligent viewpoint selection for efficient CT to video registration in laparoscopic liver surgerySpringer Science and Business Media LLC - Tập 12 - Trang 1079-1088 - 2017

Minimally invasive surgery offers advantages over open surgery due to a shorter recovery time, less pain and trauma for the patient. However, inherent challenges such as lack of tactile feedback and difficulty in controlling bleeding lower the percentage of suitable cases. Augmented reality can show a better visualisation of sub-surface structures and tumour locations by fusing pre-operative CT da...... hiện toàn bộ
A novel multi-DoF surgical robotic system for brachytherapy on liver tumor: Design and controlSpringer Science and Business Media LLC - Tập 16 - Trang 1003-1014 - 2021

Radioactive seed implantation is an effective invasive treatment method for malignant liver tumors in hepatocellular carcinomas. However, challenges of the manual procedure may degrade the efficacy of the technique, such as the high accuracy requirement and radiation exposure to the surgeons. This paper aims to develop a robotic system and its control methods for assisting surgeons on the treatmen...... hiện toàn bộ
Comparative ergonomic workflow and user experience analysis of MRI versus fluoroscopy-guided vascular interventions: an iliac angioplasty exemplar case studySpringer Science and Business Media LLC - Tập 10 - Trang 1639-1650 - 2015
Fabiola Fernández-Gutiérrez, Santiago Martínez, Martin A. Rube, Benjamin F. Cox, Mahsa Fatahi, Kenneth C. Scott-Brown, J. Graeme Houston, Helen McLeod, Richard D. White, Karen French, Mariana Gueorguieva, Erwin Immel, Andreas Melzer
A methodological framework is introduced to assess and compare a conventional fluoroscopy protocol for peripheral angioplasty with a new magnetic resonant imaging (MRI)-guided protocol. Different scenarios were considered during interventions on a perfused arterial phantom with regard to time-based and cognitive task analysis, user experience and ergonomics. Three clinicians with different experti...... hiện toàn bộ
Articulated minimally invasive surgical instrument based on compliant mechanismSpringer Science and Business Media LLC - Tập 10 - Trang 1837-1843 - 2015

In minimally invasive surgery, instruments are inserted from the exterior of the patient’s body into the surgical field inside the body through the minimum incision, resulting in limited visibility, accessibility, and dexterity. To address this problem, surgical instruments with articulated joints and multiple degrees of freedom have been developed. The articulations in currently available surgica...... hiện toàn bộ
Wavelet denoising for quantum noise removal in chest digital tomosynthesisSpringer Science and Business Media LLC - Tập 10 - Trang 75-86 - 2014
Tsutomu Gomi, Masahiro Nakajima, Tokuo Umeda
Quantum noise impairs image quality in chest digital tomosynthesis (DT). A wavelet denoising processing algorithm for selectively removing quantum noise was developed and tested. A wavelet denoising technique was implemented on a DT system and experimentally evaluated using chest phantom measurements including spatial resolution. Comparison was made with an existing post-reconstruction wavel...... hiện toàn bộ
