Evolving Era of Multidimensional Medical Imaging

Evolving Medical Imaging Techniques.

Evolving and experimental technologies in medical imaging.

Medical images are created by detecting radiation probes transmitted through or emitted or scattered by the body. The radiation, modulated through interactions with tissues, yields patterns that provide anatomic and/or physiologic information. X-rays, gamma rays, radiofrequency signals, and ultrasound waves are the standard probes, but others like visible and infrared light, microwaves, teraher...

Estimation of dynamically evolving ellipsoids with applications to medical imaging

The estimation of dynamically evolving ellipsoids from noisy lower-dimensional projections is examined. In particular, this work describes a model-based approach using geometric reconstruction and recursive estimation techniques to obtain a dynamic estimate of left-ventricular ejection fraction from a gated set of planar myocardial perfusion images. The proposed approach differs from current ej...

Medical-Imaging Stewardship in the Accountable Care Era.

M technology plays an essential role in the timely diagnosis and manage­ ment of many conditions. Lately, however, it’s become equally well known for its low­value uses and as the single largest source of per capita radiation exposure. Imaging is by far the most com­ mon service on the lists of un­ necessary tests and procedures of the Choosing Wisely campaign, and an estimated 20 to 50% of ima...
