This module provides an overview of mammography and bone densitometry, enhanced forms of X-ray technology that are used, respectively, to examine breast tissue and measure bone loss. The module also discusses quality management programs for radiographic imaging. It offers students and practitioners an understanding of the technology and techniques involved in mammography and bone densitometry, and important considerations for effective radiographic quality control. This module is an ideal resource if you are studying for the American Registry of Radiologic Technologists® (ARRT) registry exam.

You’ll learn

how to differentiate between soft tissue and conventional radiography
to identify the technology involved in mammography
to describe the procedural requirements for conducting a mammogram
to describe the technology involved and procedural considerations for conducting bone density scanning
to identify the components of an effective quality management program
how to identify the common causes of image artifacts and how they can be prevented or minimized
much more (see “content details” for more specific information)

The SIMTICS modules are all easy to use and web-based. This means they are available at any time as long as the learner has an internet connection. No special hardware or other equipment is required, other than a computer mouse for use in the simulations. Each of the SIMTICS modules covers one specific procedure or topic in detail. Each module contains:

an online simulation (available in Learn and Test modes)
descriptive text, which explains exactly how to perform that particular procedure including key terms and hyperlinks to references
2D images and a 3D model of applied anatomy for that particular topic
a step by step video demonstration by an expert
a quiz
a personal logbook that keeps track of all the modules the learner has studied and how long
