A tissue positioning system for contouring a patient tissue volume includes an axially displaceable interface having a surface configured to engage a breast or other tissue volume. A low pressure source applies a partial low pressure to the surface of the displaceable interface to secure the tissue volume to the surface, and the axially displaceable interface is biased to pull and contour the tissue volume when the tissue volume is secured to the surface. The axially displaceable interface is typically mounted on a telescoping support and the biasing is provided by the same low pressure used to secure the tissue volume.

A sensor or receiver array includes first and second pyroelectrically active electrodes formed of polyvinylidene difluoride and separated by a spacer layer that acts to electrically separate the pyroelectric layers while keeping them close enough such that they see effectively the same vibration or background acoustic excitation while maintaining sufficient separation to ensure that they generate significant differences in their pyroelectric responses. The structure provides two distinct signals (at separate timestamps), the difference between which provides a more accurate signal.
