Abstract

Many of the developments in the field of ultrasound imaging are focused on technological improvements to improve the signal to noise of the instrumentation or in the use of new techniques to increase the soft tissue contrast. Contrast in an ultrasound image is based on the strength of backscattered ultrasound. Increase in the transducer bandwidth increases the ultrasound spatial resolution, leading to higher frequencies being used to image smaller structures to provide better axial and lateral resolution. The use of acoustic microscopy has helped in reproducing scattering patterns using smaller diameter beads at frequencies between 100 and 1,000 MHz. Investigations have been conducted using instrumentation that allows ultrasonic interrogation with frequencies ranging between 1-1000 MHz.
