“…It should be noted that both of the above methods require multiple images that contain the same biopsy site. To facilitate sequential retargeting, a manifold approach based on laplacian eigenmaps (Atasoy et al, 2012) was proposed.…”

“…More recently Atasoy et al [6] propose to formulate the re-localization as image-manifold learning process. By projecting endoscopic images on low dimensional space they propose to classify and cluster the images collected during multiple interventions into manageable segments, which they claim would aid in re-localization of the biopsy sites.…”

Abstract. The screening of oesophageal adenocarcinoma involves obtaining biopsies at different regions along the oesophagus. The localization and tracking of these biopsy sites inter-operatively poses a significant challenge for providing targeted treatments. This paper presents a novel framework for providing a guided navigation to the gastro-intestinal specialist for accurate re-positioning of the endoscope at previously targeted sites. Firstly, we explain our approach for the application of electromagnetic tracking in acheiving this objective. Then, we show on three in-vivo porcine interventions that our system can provide accurate guidance information, which was qualitatively evaluated by five experts.

“…In the gastro-intestinal endoscopic optical biopsy, comparison at the same locations in a few month intervals is necessary. For the relocation of biopsy targets, Atasoy et al applied manifold learning to dimensional reduction in representing endoscopic video sequences for the clustering and classification of the sequences [97], [98]. The developed lowdimensional representations are expected to facilitate targeted optical biopsy.…”

SUMMARYThis paper reviews methods for computer assisted medical intervention using statistical models and machine learning technologies, which would be particularly useful for representing prior information of anatomical shape, motion, and deformation to extrapolate intraoperative sparse data as well as surgeons' expertise and pathology to optimize interventions. Firstly, we present a review of methods for recovery of static anatomical structures by only using intraoperative data without any preoperative patient-specific information. Then, methods for recovery of intraoperative motion and deformation are reviewed by combining intraoperative sparse data with preoperative patient-specific stationary data, which is followed by a survey of articles which incorporated biomechanics. Furthermore, the articles are reviewed which addressed the used of statistical models for optimization of interventions. Finally, we conclude the survey by describing the future perspective.
