Introduction The process of creating a physical three-dimensional (3D) printed model from medical imaging data is complicated and involves numerous steps. In order for a patient-specific anatomic model to be…
Quality Assurance (QA), defined as the maintenance of a desired level of quality in a service or a product, is a subset of the quality management system (QMS) and provides…
Introduction The United States (US) Food and Drug Administration (FDA) has overseen medical device marketing in the US since May 28, 1976, when the Medical Device Amendments to the Federal…
Introduction In medical imaging, a three-dimensional (3D) image, or volume, is often acquired by stacking up a series of two-dimensional (2D) slice images. Just as 2D images are made up…
Introduction Three-dimensional (3D) printing technologies are now entering their fourth decade of use and many medical applications now are very well established and optimized. Despite this, many in the medical…
Ultrasound In ultrasound imaging, a short burst of mechanical energy created by a transducer is introduced into the body through contact with the skin. The resulting ultrasound pulse travels at…
Computed Tomography Computed tomography (CT) has experienced enormous growth in clinical use over the past three decades (Fig. 10-1) primarily due to significant advances in image quality and a dramatic…
Magnetic Resonance Basics: Magnetic Fields, Nuclear Magnetic Characteristics, Tissue Contrast, Image Acquisition Nuclear magnetic resonance (NMR) is the spectroscopic study of the magnetic properties of the nucleus of the atom….
Radiation Detection and Measurement The detection and measurement of ionizing radiation are the basis for the majority of diagnostic imaging. In this chapter, the basic concepts of radiation detection and…
Magnetic Resonance Imaging: Advanced Image Acquisition Methods, Artifacts, Spectroscopy, Quality Control, Siting, Bioeffects, and Safety The essence of magnetic resonance imaging (MRI) in medicine is the acquisition, manipulation, display, and…
