doi: 10.1111/j.1540-8167.2009.01664.x

Figure Lengend Snippet: (a) B-mode image and (b) digital image of a RFA lesion sliced along the 30° imaging plane. Image of maximum ARFI-induced displacement overlaid onto: (c) the B-mode image and (d) the digital photograph of the lesion cross-section. Depth normalized maximum ARFI-induced displacement data overlaid onto: (e) the B-mode image and (f) the digital image of the lesion cross-section. The color bar units in (c) and (d) are μm displacement away from the transducer; in plates (e) and (f) the colors represent the fraction of the maximum displacement at a given depth.

doi: 10.1111/j.1540-8167.2009.01664.x

Figure Lengend Snippet: Examples of raw and normalized ARFI images and of the human and machine determined lesion boundaries. Each row contains images for a separate lesion. Column (a) is the maximum ARFI-induced displacement image overlaid onto the photograph of the lesion cross-section. Column (b) is the depth normalized ARFI image overlaid onto the cross-section photograph. Column (c) shows the lesion boundary traces as determined by a manual segmentation based on the digital image (black) and the automatic ARFI imaging segmentations based on the optimal (blue) and standardized (green) thresholds. Lesions 1 and 2 were imaged with the custom 128-element AcuNav™, while lesion 3 was imaged with a commercially available 64-element AcuNav™. The automatic threshold traces for lesion 3 are identical and overlap. The color bar units in column (a) are μm displacement away from transducer; in column (b) the colors represent the fraction of the maximum displacement at a given depth.
