Regulatory Perspectives for 3D Printing in Hospitals
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…
Image Segmentation and Nonuniformity Correction Methods
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…
An Abbreviated History of Medical 3D Printing
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
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 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
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
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…
