Abstract
An ultrasound phantom is adapted to provide multiple testing capabilities for quality assurance on ultrasound scanners. The phantom includes a section with an array of target spheres which allow the ability of the scanner to delineate the intersection of a plane of symmetry of the scan slice with diagnostic objects to be determined. Other sections allow low contrast resolution of large objects, spatial resolution regarding lateral and axial dimensions, maximum visualization depth, image gray level uniformity, and distance measurement accuracy to be determined. The phantom may be utilized to provide comparative tests of various scanners and to monitor the performance of a particular scanner over time to determine any changes in the performance of the scanner.
