<p>The diagnostic test tool is designed to simultaneously compare and evaluate measurement accuracy on a wide range of radiological imaging apparatus. It enables comparison of known reference values of a test object against those values generated by manufacturer software image measurement programs commonly found on diagnostic viewing facilities. The tool can compare measurement accuracy across most radiological imaging platforms including digital subtraction angiography, computed tomography, magnetic resonance imaging, radio-fluoroscopy, and newer combination scanners. These can now be collectively compared and evaluated, along with manufacturer reporting software including multi-planar reconstruction, maximum intensity projection, and curved reconstructions. The construction of its cross-sectional modules will provide a reference diameter on each constructed image and will allow distance in the z-axis to be accurately referenced. Comparison of this reference value with what is measured at the reporting platform will give a measure of compliance / non-compliance of the imaging equipment with the reference. Figure 1 shows an embodiment of the invention comprising a frame 1, vertical column 6, and sockets 8 into which can be fitted measurement tubes / reference tools as shown in figures 8, 9 etc.</p> |
