Giant phyllodes tumor occupying the whole breast in a young female: feasibility of mastectomy and immediate reconstruction

Autor: Kolia, Aikaterini K. Kalles, Vasileios Zografos, Constantinos G. and Chamzin, Alexandros Michalopoulos, V, Nikolaos

Giant phyllodes tumors are rare fibroepithelial breast neoplasms typically >10 cm by definition. The best investigation for preoperative diagnosis is core biopsy, although it is often difficult for the pathologist to distinguish fibroadenomas from ph

In radiotherapy treatment planning that is only based on magnetic resonance imaging (MRI), the electron density information usually obtained from computed tomography (CT) must be derived from the MRI by synthesizing a so-called pseudo CT (pCT). This

We present a novel approach for segmenting different motions from 3D trajectories. Our approach uses the theory of transformation groups to derive a set of invariants of 3D points located on the same rigid object. These invariants are inexpensive to

We introduce a method to combine the color channels of an image to a scalar valued image. Linear combinations of the RGB channels are constructed using the Fisher-Trace-Information (FTI), defined as the trace of the Fisher information matrix of the W

Dihedral Color Filtering

Autor: Reiner Lenz, Martin Solli, Vasileios Zografos

Publikováno v: Advanced Color Image Processing and Analysis ISBN: 9781441961891

This volume does much more than survey modern advanced color processing. Starting with a historical perspective on ways we have classified color, it sets out the latest numerical techniques for ana ...
