Acquisition of tomographic ultrasound.
Conventional ultrasound image-data and spatial information from the tracking system (a) were continuously recorded during a whole organ scan. The tomographic volume (b) was alined in sagittal orientation (c) and series of transversal planes were computed (d). The person (a) gave written permission to use this photo.

Impact of image quality and artifacts on tomographic ultrasound.
Liver and kidney lesion are shown in conventional (left) and tomographic (right) ultrasound. Panels A and B represent examples with good image quality of the tomographic reconstruction. Panel C shows artifacts in the reconstructed image (right) which impairs the detection of the small hyperechoic lesion.
