Describes the use of nuclear medicine techniques in diagnosis and therapy. Describes instrumentation in diagnostic nuclear medicine and predicts future trends in nuclear medicine imaging technology. (Author/MM)

Explains how x-ray doses to patients are measured. Describes how different techniques expose patients to differing amounts of ionizing radiation. Compares these figures with other natural and man-made sources. (Author/MKR)

Describes principles involved in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). (MKR)

Very sensitive SQUID (superconducting quantum interference device) detectors are used in the technique known as magnetoencephalography to provide dynamic images of the brain. This can help our fundamental understanding of the way the brain works and may be of particular use in treating disorders such as epilepsy. (Author/MKR)

Describes an experience with the use of a radioactive tracer in medicine. Discusses the methodology of how the tracer was used. (CCM)

Discusses the field of nuclear medicine. (MKR)

Indicates the difficulties of teaching concepts beyond light and color and creating memorable learning experiences. Recommends sequential activities using the mystery box approach to explain how scientists and doctors use photon applications. (YDS)

Describes the physics of Doppler ultrasound used in measuring the velocity of blood flow. Discusses medical applications of this technique. (Author/MKR)

Describes computed tomography (CT), a medical imaging technique that produces images of transaxial planes through the human body. A CT image is reconstructed mathematically from a large number of one-dimensional projections of a plane. The technique is used in radiological examinations and radiotherapy treatment planning. (Author/MM)

Presents a brief history of magnetic resonance imaging (MRI) and an overview of the underlying physics followed by a short survey of current and emerging clinical applications. (Author/MM)

Presents an activity, including worksheets, that introduces the ideas behind CAT scanners and explains how they are used in medical research and diagnosis. (MKR)

Highlights the connection between the achievements of Moseley and the spectrum of the hydrogen atom, the Bohr theory, and Slater's rules for screening constants. Uses modern data to show that Moseley's equation is actually an approximation and discusses the significance of this fact. (JRH)

Redgram (Cajanus cajan L.) extracts have been analyzed for the protease inhibitors using a new, sensitive, simple, and rapid method for detection of electrophoretically separated protease inhibitors. The detection involves equilibrating the gel successively in the protease assay buffer and protease solution, rinsing the gel in assay buffer, and…

The goal of this unit is to help children explore the aspects of X-rays and radiology in society. Students develop an understanding that X-rays are silhouette images, beneficial in health care, and a part of radiology. The history and development of X-rays as well as their applications in advancing technology are also explored. The unit is…
