Development of High Frequency Annular Array with a Novel Structure for Medical Imaging [PDF]
, 2010 High frequency annular arrays offer a number of advantages in medical imaging. A novel 2mm diameter, 7-element, 40MHz array using equal width elements, instead of the more conventional equal area ones, has been designed and evaluated.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Modelling of a novel high-impedance matching layer for high frequency (>30 MHz) ultrasonic transducers [PDF]
, 2013 This work describes a new approach to impedance matching for ultrasonic transducers. A single matching layer with high acoustic impedance of 16 MRayls is demonstrated to show a bandwidth of around 70%, compared with conventional single matching layer ...
