Registration-based segmentation uses registration method to perform seg-mentation However, registration is in general different from segmentation To clarify the differences, we define three related problems here, namely segmentation, registration, and correspondence The most general forms of these definitions are given 4
Segmentation, 2D-3D Registration, and Uncertainty Propagation Main advantages of minimally invasive surgery are less operative trauma, faster recovery, and less
MINIMALLY INVASIVE NAVIGATED LIVER techniques combine segmentation and registration algorithms to estimate the actual tumor position during the surgical procedure
4) Segmentation of the first slice, which comprises of deformable registration to align all the phases, segmentation of the average temporal image and minimal surface segmentation of all phases; and 5) Segmentation of the other slices We will describe each of these steps in more details in the next sections
minimally invasive laparoscopic cholecystectomy intervention that can be used for the construction of an adaptive calibration-free medical augmented reality system In particular, the pro-posed method consists of three steps, namely, a segmentation of 2D laparoscopic images using a combination of photomet-
processing methods such as segmentation, registration and visualization play a critical role Percutaneous renal intervention plays an important role in several minimally-invasive surgeries of kidney, such as Percutaneous Nephrolithotomy (PCNL) and Radio-Frequency Ablation (RFA) of kidney tumors, which refers to a surgical

Prostate Cancer : Computer Aided-Diagnosis on
dHospital La Pitie-Salpetriere, Boulevard De L’Hopital, Paris, France ABSTRACT Prostate cancer (PCa) is one of the most common cancers in men, being also the second most deadly cancer after lung cancer There is increasing interest in active surveillance and minimally invasive focal therapies in PCa to avoid morbidities associated with whole gland therapy Tumor volume represents an

A Comparison of US versus MR Based 3D Prostate Shapes
prostate segmentation first uses radial basis function interpolation to construct a 3D point distribution model for each prostate Next, a modified principal axis transformation is utilized for rigid registration of the US and MR images of the same prostate in preparation for the following shape comparison Then, statistical shape models are used to capture the segmented 3D prostate geometries
