Development of High Frequency Annular Array with a Novel Structure for Medical Imaging
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. It showed an excellent lateral resolution (LR) with a good secondary lobe (SL) response, comparable to conventional arrays operating in excess of 70MHz, which the frequency range causes troubles in annular arrays. The novel array with strong-focusing opens a new way to improve the image quality at relatively low operating frequencies.

Abstract
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. It showed an excellent lateral resolution (LR) with a good secondary lobe (SL) response, comparable to conventional arrays operating in excess of 70MHz, which the frequency range causes troubles in annular arrays. The novel array with strong-focusing opens a new way to improve the image quality at relatively low operating frequencies.
