A set of test objects designed to be used quickly and easily on a annual / commissioning basis to provide an ongoing check of imaging performance, particularly those aspects which are most liable to deterioration. Used for CR and DDR, the kit enables the following checks to be made: ? Erasure cycle efficiency ? Image Retention ? Sensitivity index consistency/sensitivity ? Uniformity ? Scaling errors ? Blurring and Stitching Artefacts ? Limiting resolution (45o only) ? TCDD (Threshold Contrast Detail Detectability)
