Studies discussed in this presentation are concerned with application of 3. 5 and 4 MHz, lead metaniobate and 5 and 7. 5 MHz PVDF (polyvinylidene fluoride) transducers for examination of the compressed breast and for examination of a compressed breast phantom. Emphasis is placed in the in vivo studies on determining whether high frequency transducers can provide increased information on the internal structure of fibroadenoma masses. The phantom studies are concerned with the extent of beam defocusing for masses located at different depths in a compressed breast phantom. The complete penetration of the sound beam through the breast and the excellent resolution throughout the breast is noted.
