UCL Cancer Institute Multidisciplinary Seminar Series

 The UCL Cancer Institute Multidisciplinary Seminar Series highlights research from disciplines across UCL. The monthly seminars aim to present new and exciting work to Cancer Institute researchers and to forge collaborations across different disciplines in UCL.

Development of a system for image guided laparoscopic resection

Dr Matt Clarkson - Dept of Medical Physics and Biomedical Engineering

In the UK approximately 1800 liver resections are performed annually for primary or metastatic cancer. However this is a major global health problem and 150,000 patients per year could benefit from liver resection. Currently only about 10-20% of patients are considered suitable for laparoscopic liver resection, mainly those with small cancers on the periphery of the liver. Larger lesions and those close to major vascular/biliary structures are generally considered high risk for the laparoscopic approach. However, pre-operative imaging modalities such as computed tomography (CT) can clearly identify the location of vessels and tumours. We are developing a guidance system to present CT scan data, overlaid onto laparoscopic video, in real time, in order to guide the surgeon and enable safer laparoscopic procedures. This is a technically challenging endeavour, and I will describe the system as a whole, give an overview of some of the technical challenges and present our results to-date. 

Inferring geometry from endoscopic video during minimally invasive cancer surgery

Dr Dan Stoyanov - Dept of Computer Science

In this talk, I will discuss some of our past and ongoing work in processing monocular and stereo endoscopic video in order to enhance the targeting and localisation capabilities of the surgeon during minimally invasive cancer treatment. Computer and robotics assisted interventions can benefit from visual computing by enhancing visualisation at the surgical site, as well as, the surgeon’s navigation within the anatomy and potentially surgical dexterity when coupled with robotic instrumentation. We have investigated various possible applications for vision approaches in robotic assisted surgery and computer assisted interventions and I will discuss some of the potential clinical needs and our work in different surgical specialisations.

A light lunch will be provided after the seminar
