In Memoriam: ACSM Mourns Loss, Recognizes Accomplishments Of 8th President

The American College of Sports Medicine was saddened to learn of the passing of its 8th President, Elsworth Buskirk, Ph.D., FACSM, on March 28.
Buskirk was an emeritus professor of applied physiology and human nutrition at Pennsylvania State University. He was a distinguished researcher and educator who contributed to the understanding of [...]

Turning Noise Into Vision

A new technique for revealing images of hidden objects may one day allow pilots to peer through fog and doctors to see more precisely into the human body without surgery.
Developed by Princeton engineers, the method relies on the surprising ability to clarify an image using rays of light that would typically [...]

Utility And Health-Related Quality Of Life In Prostate Cancer Patients 12 Months After Radical Prostatectomy Or Radiation Therapy

UroToday.com – The most common curative treatments for localized prostate cancer (PC), radical prostatectomy (RP) and radiation therapy (RT), have significant effects on quality of life. Most studies measured quality of life using psychometric instruments. Another approach uses the concept of utility. Utility is a global measure, scaled between 0 (dead) and [...]

Radiation Treatment: Age, Gender Can Affect Risk

Doctors have a clearer picture than ever before of how much radiation reaches sensitive tissues during routine X-rays and similar imaging, thanks to sophisticated models of the human body being developed at the University of Florida.
“We’re building a rich library of computer simulation tools and 3-D patient models that will make [...]

Startup to develop new solid-state technology at UCLA for use in medical imaging

While today many medical-imaging needs are being met with traditional vacuum tube–based technology, large segments of the X-ray–imaging market are poorly served, and there is widespread demand for both performance improvements and cost reductions.
Based on groundbreaking patented technology licensed from UCLA, startup company Radius Health is developing a lightweight, flat-panel [...]

Energetic Quanta: Gamma-Rays

Energetic Quanta: Gamma-Rays

Gamma rays…

Are emitted from the nucleus to trim excess energy.
Tend to carry higher energies than X-rays, but this does not have to be the case

For example, after a larger energy decay particle (e.g. a beta particle) is emitted, the nucleus may still be slightly unstable (i.e., the atom [...]

Energetic Quanta: X-rays & Gamma-Rays

Energetic Quanta: X-rays & Gamma-Rays

Gamma rays and X-rays are types of photons…

That represent pure electromagnetic energy
That progress at the speed of light
That may pass through all human tissues unimpeded and unchanged
Having no mass or charge, are neither attracted to nor repulsed by charged particles
Gamma-rays originate from the nucleus

X-rays originate from electron clouds
