The Imatest version of the chart includes registration marks for automatic region detection and slanted edges for convenient MTF comparison. Slanted-Edge versus Siemens Star contains a detailed comparison of results. The Siemens Star is included in the ISO 12233:2014 standard along with the slanted-edge and hyperbolic wedge, all of which are supported by Imatest modules. When placed off-axis, the chart will have segments that cover sagittal and tangential directions in addition to vertical and horizontal directions. Since the Imatest Star module analysis is extremely noise-resistant, measurements are highly repeatable. Siemens star MTF20 (the spatial frequency where MTF is 20% of its low frequency value) is a good estimate of limiting resolution. Privacy, Terms.The Sinusoidal Siemens Star test chart allows you to measure MTF and limiting resolution with a chart that provides angular response and may be less affected by signal processing (especially sharpening) than slanted-edges.
