Breast Imaging: Mammography Mammography is a radiographic examination that is optimized for detecting breast cancer. Breast cancer screening with mammography can catch cancers at an earlier, more treatable stage. Technological…
Radiography Radiography involves the production of a two-dimensional image from a three-dimensional object, the patient (Fig. 7-1). The procedure projects the x-ray shadows of the patient’s anatomy onto the image…
Fluoroscopy Fluoroscopy systems provide real-time or near real-time x-ray imaging of patients. Fluoroscopy systems provide the temporal resolution necessary for the operator to use image guidance for the placement of…
X-ray Production, Tubes, and Generators X-rays are produced when highly energetic electrons interact with matter, converting some or all of their kinetic energy into electromagnetic radiation. The x-ray tube insert…
Interaction of Radiation with Matter This chapter introduces the concepts and principles that govern x- and γ-ray photon interactions with matter and the energetic electrons those interactions set into motion….
Medical Imaging Informatics In healthcare, medical informatics represents the process of collecting, analyzing, storing, and communicating information (data) that is crucial to the provision and delivery of appropriate patient care…
Radiation and the Atom Radiation simply refers to energy that propagates through space or matter. Two categories of radiation of importance in medical imaging are electromagnetic radiation (EMR) and sub-atomic…
Introduction to Medical Imaging Radiological imaging of the intact human body requires some form of energy to enter the body, interact, and then deliver a signal to a detector, typically…
