X-Ray Dosimetry in Projection Imaging and Computed Tomography 11.0 INTRODUCTION Radiation dosimetry encompasses the measurement and calculation of ionizing radiation energy deposition into matter—this chapter addresses the application of dosimetry…
Nuclear Tomographic Imaging—Single Photon and Positron Emission Tomography (SPECT and PET) 19.0 INTRODUCTION The focus of this chapter is SPECT and PET imaging. Specifically, the chapter covers the principles of…
Image Quality 4.0 INTRODUCTION At a fundamental level, image quality is about diagnostic accuracy, which is a difficult quantity to measure. Because of this, most image quality measures are based…
Breast Imaging: Mammography 8.0 INTRODUCTION 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…
Radiation Biology 20.0 INTRODUCTION Since the discovery of X-rays and radioactivity over 120 years ago, radiation biology research has amassed more information about the effects of ionizing radiation on living…
Nuclear Imaging—The Gamma Camera 18.0 INTRODUCTION The focus of this chapter is the underlying principles and components of the gamma camera and its use in planar single photon nuclear imaging….
Radioactivity and Nuclear Transformation 15.0 INTRODUCTION The nuclei of unstable atoms undergo a transformation during which ionizing radiation (which can be in the form of particles or waves or both)…
X-Ray Production, Tubes, and Generators 6.0 INTRODUCTION This chapter describes the x-ray production process, characteristics of the x-ray beam, x-ray tube design x-ray generator components, and factors that affect exposure…
Radiography 7.0 INTRODUCTION This chapter explains how the technology described in Chapter 6 is used to project the shadows of a threedimensional object onto a two-dimensional detector to produce a…
Interaction of Radiation with Matter 3.0 INTRODUCTION This chapter introduces the concepts and principles that govern x- and γ-ray photon interactions with matter and the energetic electrons those interactions set…
