MLC QA – The Garden Fence Test
Presented at the 2016 Radiosurgery Society Scientific Meeting MLC QA – The Garden Fence Test 0.1mm mm mm mm mm mm mm Induced Individual leaf errors 0.1 mm to 1.0 mm Increments of 0.1 mm “Detection” occurs if a cluster of pixels is simultaneously above a threshold with SNR above 10. Mean pixel difference values are used as “Warning” and “Error Thresholds” as well as for trend analysis.
