20150305705 | PHANTOM AND METHOD FOR IMAGE QUALITY ASSESSMENT OF A DIGITAL BREAST TOMOSYNTHESIS SYSTEM - A phantom for image quality assessment of digital breast tomosynthesis apparatus includes at least one set of beads arranged as a first ramp and as a second ramp in respective proximate parallel vertical planes in a reverse staircase pattern along a vertical direction with a final bead of the first ramp and an initial bead of the second ramp being located at substantially the same intermediate height within the phantom. The beads and additional test objects may be positioned in non-overlapping locations within the phantom to facilitate determination of multiple image quality parameters with a single scanning sequence of the phantom. | 10-29-2015 |
20120128123 | WAVE RAMP TEST METHOD AND APPARATUS - Method and apparatus are provided for use with a tomographic imaging device. A test object comprising a plurality of angled ramps may be provided to facilitate evaluating performance of the tomographic imaging device. A method for evaluating performance of a tomographic imaging device includes scanning the test object to produce a tomographic slice image and performing analysis on a waveform profile extracted from the image, to determine spatial performance of the tomographic imaging device. A tomographic imaging device may be provided comprising a scanning device and a data processing unit for performing a method of evaluating performance of the tomographic imaging device. | 05-24-2012 |
