2D Angular Correlation of Annihilation Radiation: Current Trends and Future Possibilities

Stone treatments: current trends and future possibilities.

With the widespread distribution of shock wave lithotripsy (SWL) by the late 1980s, this noninvasive technology became the preferred approach to most patients with symptomatic urolithiasis. The extraordinary success of the original Dornier HM3 lithotriptor had tremendous appeal to patients and physicians alike. SWL was established as the preferred initial treatment approach for 80% to 90% of ca...

Fermi surface of CeCu 2Si 2 by 2D angular correlation of positron annihilation radiation

We have carried out 2D angular correlation of positron annihilation radiation measurements on oriented single crystals of the heavy-fermion superconductor CeCu2Si2. Measurements have been made at 50 and 4 K which are above and below the Kondo temperature, TK;15 K, for this compound. The measurements show a small temperature dependence. Experimental results have been compared with linear muffin-...

radiation Induced Xerostomia: current concepts and Future trends

Radiation induced xerostomia is a persistent clinical presentation that affects the quality of life in head and neck cancer patients even with the best of the intensity modulated radiotherapy protocols. Comprehensive review of the anatomic, histologic, developmental and neuronal entities of salivary glands from a regenerative perspective, ensuing radiation is taken. It also evaluates the system...

Cochlear implants: current designs and future possibilities.

The cochlear implant is the most successful of all neural prostheses developed to date. It is the most effective prosthesis in terms of restoration of function, and the people who have received a cochlear implant outnumber the recipients of other types of neural prostheses by orders of magnitude. The primary purpose of this article is to provide an overview of contemporary cochlear implants fro...
