High-Resolution 3D Acoustic Maps: Abdominal Wall

Imaging the primary organs housed in the abdomen requires the propagation of acoustic waves through the abdominal wall. The achievable imaging quality decreases as the thickness of this tissue layer increases. In order to better investigate the causes of this reduction in imaging quality, a realistic in vivo simulation model is required. Presently, a very limited number of two-dimensional abdominal tissue models are available. We are currently developing methods for acquiring and segmenting three-dimensional datasets to be used in simulations investigating the interactions between ultrasonic waves and the microscopic tissue layers present in the abdominal wall. In addition to this particular imaging interest, these tissue models will serve as an indispensable tool in producing realistic simulations of imaging through the abdominal wall.
