I-44: 3D Ultrasonography of Ovarian Tumors

A prospective study was conducted at the OB/GYN department of Kasr El Eini hospital, Cairo University from Jan 2000 - Oct 2002. The study included 51 patients in the age group between 40-70 years (including pre and post menopausal women). All patients were subjected to following after taking a consent from each patient: Complete clinical evaluation; including history taking and clinical examina...

Tridimensional Regression for Comparing and Mapping 3D Anatomical Structures

Shape analysis is useful for a wide variety of disciplines and has many applications. There are many approaches to shape analysis, one of which focuses on the analysis of shapes that are represented by the coordinates of predefined landmarks on the object. This paper discusses Tridimensional Regression, a technique that can be used for mapping images and shapes that are represented by sets of t...

Application of 3D Ultrasonography in Detection of Uterine Abnormalities

Volume Reconstruction from Sparse 3D Ultrasonography

3D freehand ultrasound has extensive application for organ volume measurement and has been shown to have better reproducibility than estimates of volume made from 2D measurement followed by interpolation to 3D. One key advantage of free-hand ultrasound is that of image compounding, but this advantage is lost in many automated reconstruction systems. A novel method is presented for the automated...
