Three-Dimensional Volumetric Scans: Acquisition Technique and Volume Content Viewing

Conference paper

Abstract

The three-dimensional (3-D) presentation of organs, tumors, and tissue structures is used routinely with data from computed tomography (CT) and magnetic resonance imaging (MRI). In both procedures sequences of parallel two-dimensional (2-D) slices are acquired. This information can be reconstructed into 3-D presentations by means of digital image processing. The main disadvantages of these procedures are long acquisition time and, with respect to CT, the administration of ionizing radiation. Both methods are very complex, expensive, and not readily available as a routinely used imaging tool. Furthermore, the application in fetal diagnostics is not recommended. Sonography, with its well-known advantages of fast handling, maximum patient safety, and vast availability, shows a promise as a basis for 3-D presentation. Of course, we must take into account the poorer geometrical resolution compared to CT and MRI, although high-end echographic systems today are able to offer very good performance with resolutions below 1 mm.
