| Summary:
We developed a system for whole-body human ultrasound tomography in
reflection and transmission modes. A custom 512-element ultrasound receiver
array with a rotating single-element ultrasound transmitter are used to
generate 2D isotropically resolved images across the entire human
cross-section. We demonstrate this technique in regions such as the abdomen and
legs in healthy volunteers. Compared to handheld-probe-based ultrasonography,
this approach provides a substantially larger field of view, depends less on
operator training, and obtains quantitative tissue parameter profiles in
addition to reflectivity images. Whole-body ultrasound tomography could be
valuable in applications such as organ disease screening, image-guided needle
biopsy, and treatment monitoring.
