Ultra-Wideband Imaging Systems for Breast
Cancer Detection
Hossein Kassiri Bidhendi, Hamed Mazhab Jafari and Roman Genov
Abstract
In this chapter we will begin with an introduction to ultra-wideband
(UWB) communication systems and their application in medical imaging. The rest
of the chapter will present design of UWB receiver and transmitter blocks (low-noise
amplifier (LNA), Multiplier and pulse generator) that are designed, fabricated and
tested by authors. The reader will have a good understanding of a UWB transceiver
system design and its advantages for breast cancer detection after reading this chapter.

Motivation
Worldwide breast cancer is one of the leading causes of death among women. Only
in the USA, tens of thousands of deaths are reported yearly because of this type of
cancer. 26 percent of all types of cancers among women are breast cancer [
1
]. It is
now well-known that a high percentage of patients with this type of cancer can be
cured if diagnosed in the early stages. There are many ongoing research projects to
develop and improve imaging systems to help early detection of this type of cancer.
This includes works which are concentrated on improvement of image processing or
imaging system optimization using new technologies.
Ultra-wideband (UWB) communications is one of the newest technologies em-
ployed in imaging systems that are utilized for human's body imaging. The motivation
is mainly based on using ultra-narrow pulses in the time domain to detect and con-
trast between normal and malignant tissues. This has initiated many research projects
based on using this technology for imaging of a particular organ of body including
heart, lung, breast, and organs involved in breath and speech mechanisms [
