Physics for non-physicists

Can atomic physicists help reinvent Introductory Physics?

Much effort has been and is being devoted to the reform of the teaching of physics. This has led to many new and imaginative approaches to the delivery of the course material, but a perusal of today’s Introductory Physics textbooks indicates that their basic structure has changed little in over fifty years. A radical restructuring is proposed that begins with a modern atomic picture rather than...

MR Physics for Physicists / B1 Shimming and Parallel Transmission

METHODS: Currently, among other means, modifications of the applied RF pulses are investigated to cope with the mentioned B1 inhomogeneities. First, using a coil array for RF transmission, standard slice selective pulses can be transmitted with different weights in the different array elements (see, e.g., [2-4]). These weights, i.e., amplitude and phase of each element, are designed to yield a ...

An overview of CEST MRI for non-MR physicists

The search for novel image contrasts has been a major driving force in the magnetic resonance (MR) research community, in order to gain further information on the body's physiological and pathological conditions.Chemical exchange saturation transfer (CEST) is a novel MR technique that enables imaging certain compounds at concentrations that are too low to impact the contrast of standard MR imag...

AAPM Medical Physics Practice Guideline 3.a: Levels of supervision for medical physicists in clinical training

The American Association of Physicists in Medicine (AAPM) is a nonprofit professional society whose primary purposes are to advance the science, education and professional practice of medical physics. The AAPM has more than 8,000 members and is the principal organization of medical physicists in the United States.The AAPM will periodically define new practice guidelines for medical physics prac...
