The tissue-mimicking phantom for use in routine technical quality assurance (TQA). The PVA based material mimics the sound velocity and acoustic attenuation of the human tissue, is nontoxic, durable and easy to handle and maintain. Comparable and reproducible results can be achieved from a single image, making this a perfect daily QA tool. To determine the spatial resolution of phantom images, a modulation transfer function (MTF) is calculated by the Diagnomatic software using radial MTF algorithm. In addition radial MTF test object the phantom also contains structures for geometry assessment.
