Automatic Intraoperative Tracking for Workflow and Dose Monitoring in X-Ray-based Minimally Invasive Surgeries

Abstract

The goal of this project is the investigation of multimodal methods for the evaluation of interventional workflows in the operation room. This topic will be researched in an international project context with partners in Germany and in Brazil (UNISINOS in Porto Alegre). Methods will be developed to analyze the processes in an OR based on signals from body-worn sensors, cameras and other modalities like X-ray images recorded during the surgeries. For data analysis, techniques from the field of computer vision, machine learning and pattern recognition will be applied. The system will be integrated in a way that body-worn sensors developed by Portabiles as well as angiography systems produced by Siemens Healthcare can be included alongside.

OCT-OCTA Segmentation of the Bruch’s Membrane in the Presence of Pathology:
Because of the ever increasing size of OCT(A) data sets, manual segmentation of ocular layers is typically impractically laborious, necessitating the usage of automatic algorithms. While automatic segmentation of ocular layers in the normal eye can be challenging, automatic segmentation in the presence of pathology, which often causes significant ocular distortions, is more challenging still.
Perhaps nowhere is the demand for accurate segmentation more stringent than in OCTA analysis of the choriocapillaris. Analysis of the choriocapillaris is of great interest in studying a number of diseases, including age-related macular degeneration (AMD) and diabetic retinopathy (DR), where the choriocapillaris is thought to play an important role. En face OCTA analysis of the choriocapillaris typically requires segmentation of Bruch’s membrane (BM), an acellular matrix situated between the retinal pigment epithelium (RPE) and choriocapillaris.

However, to our knowledge, all previous publications on segmenting the BM have exclusively used OCT data. We think that OCTA data can be used synergistically alongside OCT data to segment Bruch’s membrane, as well as other ocular structures.

As such, the scope of this project is to explore different ways of incorporating and exploiting the additional information provided by the OCTA data in order to get more accurate and robust segmentation results for the BM in the presence of pathology.

This project is carried out in collaboration with Prof. Fujimoto’s Biomedical Optical Imaging and Biophotonics Group at MIT in Cambridge, USA.
