Registration of CT and X-ray

By R. A. / 23/02/2017 / RSIP Vision Learns / No Comments

Registration is a phase of orthopedic surgeries in which a visualization system is called to support the surgeon. This system provides real time view of the surgery environment and the information from the CT imaging. Two different steps of registration are executed here: tracking system registra...

Geographic Atrophy Segmentation Using SD-OCT

By R. A. / 28/11/2016 / RSIP Vision Learns / No Comments

In a previous article, we talked about Geographic Atrophy segmentation in 2D images. This article focuses on how OCT images shed light on the development of Geographic Atrophy (GA) pathology. This spectral-domain optical coherence tomography (SD-OCT) modality with its 3D information enables a bet...

Multi-modal registration of retina images

By R. A. / 08/11/2016 / RSIP Vision Learns / No Comments

Multi-modal registration of retina images is a process by which pictures taken with different modalities and/or at different times are registered. This is done principally when tracking some kind of condition concerning the patient, e.g. the evolution of a disease. One of the things that ophthalm...

Planning of screw insertion trajectory

By R. A. / 27/07/2016 / RSIP Vision Learns / No Comments

Robotic assisted minimally invasive surgery has changed the face of surgery. The use of robotic aid in surgery can be traced back to the mid-1980s, when robotic systems were used to create precise incisions, cuts and drills. From the late 1990s onwards, robotic surgery has taken a leap forward wi...

Anatomical surface reconstruction with sparse set of points

By R. A. / 20/07/2016 / RSIP Vision Learns / No Comments

Advance navigation techniques in orthopedic surgery allow physicians to construct 3D models of patients’ anatomical parts. Such models are especially useful for surgery planning and guidance during operation. Three-dimensional model overlay on images acquired from various modalities facilitated i...
