Chapter 1- Introduction

The importance of Advances in technology is of the utmost importance, not only to improve quality in imaging systems in the radiology department but to improve quality of life. As radiographers working in a constantly busy environment we sometimes tend to forget we are tending to patients that are extremely sick or even the basic concept of us administering radiation to patients in order to achieve a certain image.

Throughout the years, advances have been made possible where there are such great advantages for everyone involved: patients, Radiographers, Radiologists, referring physicians, etc.

Firstly, digital mammography, this is where the screen or film system is replaced with a detector that converts the incoming x-ray photons into an electrical signal that is digitized and stored onto an online archiving system (PACS) this allows us to store and send images much in a much quicker and easier manner whilst reducing the risk of loosing images.

One of the primary goals with regards to mammography is to achieve a high level of contrast between the lesion and surrounding breast tissue with digital radiography, we are able to manipulate the images’ contrast and density to allow for optimal imaging and diagnosis, this allows us to minimize exposure to the patient but because image quality is related to dose, compromise is necessary and this unfortunately causes an increase in radiation absorption to the patients surrounding tissue as low energy x-rays are used to create a high quality image and are easily attenuated. The second advancement in mammography is Computer-Aided Detection (CAD.) This is a computer program that helps Radiologists in detecting any abnormalities within the breast tissue on a mammogram. With the CAD the program “highlights” any area or lesion that may be considered abnormal with regards to density, mass or calcifications that could be a presence of cancer – this allows the radiologist to review the area and decide whether or not that area actually is abnormal or
