Our Research Work


Instrument Detection and Tracking

Tracking surgical instruments using the live video feed enables us to provide guidance and navigation assistance to the surgeon.

Stereo Reconstruction

Reconstruction of the surgical environment has involves building 3D models for the tissue surfaces while localising the camera within that model. This has important applications for augmented reality within surgery.

Non-rigid Registration

This involves aligning deformable models captured pre-operatively with imaging modalities such as MRI and CT. Aligning models can provide surgeons with details about tumors beneath the surface of the tissue.

Real-Time Non-Rigid Deblurring

Capturing images can result in complex blurring effects which make surgery more challenging. Using blurring models we hope to reduce these effects.

Body Surface Modelling

Reconstruction of the outer surface of the human body has important applications for evaluation of surgical treatment. Using structured light sensors such as the Kinect we can build up realistic 3D models.

Non-rigid Surface Tracking

Tracking the surface of the tissue which is deforming due to breathing and blood flow can allow tool-tissue interaction modelling. This can be used as part of a haptics framework in robotics and minimally invasive surgery.

Laparoscopic Liver Surgery

We are working on image guidance projects to assist surgeons while they perform laparoscopic liver surgery. By providing pre-operative imaging data to the surgeon while he operateswe can help in visualizing sub-surface structures or delimiting resectioning targets.

Robot Assisted Prostatectomy

Prostatectomy is one of the original applications of robotics to surgery. Today the majority of cases in UCL hospitals are carried out using robotic systems. We are working on registering pre-operative MRI scans to the prostate to assist the surgeon during resectioning procedures.

Aortical Valve Repair

Replacing the aortic valve with a robotic system provides many benefits over typical open body techniques where a 6-10cm incision must be made to reach the heart. However, dealing with the dynamic motion of the heart during surgery is challenging and our work is based around reducing these difficulties.

Neurosurgery

Image guidance has great potential to assist surgeons during neurosurgery. However, challenges arise when translating pre-operative imaging to intra-operative procedures. Our work aims to reduce these challenges by modelling the deformation that occurs between pre- and intra-operative scans.

Breast Cancer Surgery

We are working on methods for detecting and reconstructing breast surfaces to assist with breast cancer treatment projects. Through this we hope to provide better targeting for radiotherapy as well as automatic post-operative aesthetics quantification.

Fetal Surgery

A new project at our group. Here we will be looking at methods of operating using micro-instruments on fetuses. Operating on a fetus using open body techniques is too traumatic but methods of accessing the delicate anatomy are being investigated with robotic minimally invasive systems.

Biophotonics

We are looking at methods of analysing the interaction between light, sound, radiation and tissue to provide useful information during surgery. This can range from analyising the blood perfusion changes during operations to using fluorescence to detect tissue state changes caused by diseases such as cancer.

Surgical Skill Analysis

Assessing the skill of trainee surgeons is particularly important in light of developments in minimally invasive techniques. We are exploring methods of quantifying the skill of surgeons as well as highlighting areas of technical weakness.
