PROJECT TITLE :

Evaluation of 3-D Acquisition Surfaces for Radar-Based Microwave Breast Imaging

ABSTRACT:

This study investigates the impact that the acquisition surface has on the interior coverage of an object in the context of radar-primarily based close to-field microwave (MW) breast imaging. We define an acquisition surface as the surface over, which knowledge are collected. Three totally different 3-dimensional (three-D) data acquisition surfaces are investigated: 1) cylindrical, two) hemispherical, and three) patient specific. Three three-D numerical breast models are used for the study. A realistic ultra-wideband (UWB) antenna generates incident fields and records the entire fields. The responses from targets are analyzed, and object coverage is evaluated in terms of range distances, cross-range distances, and cumulative radiated power directed into the item by the antenna array embedded in the acquisition surface. Pictures are fashioned to verify these observations. We tend to demonstrate that a patient-specific acquisition surface provides larger responses from targets, superior object coverage and improved images compared to the opposite acquisition surfaces studied.
