Abstract
An ultrasound test phantom includes a block of human-tissue-mimicking material having a top surface and spaced-apart groups of targets embedded therein. Each group is located at a unique depth region within the block as measured from the top surface. The targets in each group include a first linear target spaced-apart from a second linear target. For each group, the first linear target extends in a first direction at a first depth of the depth region associated therewith, and the second linear target extends in a second direction at a second depth of the depth region associated therewith. When viewed from the block's top surface, a crossing point is defined where the first direction and second direction cross at an angle between 10° and 170°. For each group, the crossing point is located along a line perpendicular to the block's top surface.
