X射线成像的最新发展已经产生了许多使用扫描的X射线束来曝光射线照相胶片或电子检测器阵列的模态。在这些技术中，有那些专注于通过扫描狭缝或扫描轮技术来提高散射抑制的技术。本说明概述了一个简单的变化，传统的轮准直器的几何形状，保持恒定的光束速度沿着扫描线的长度，并允许在轮的大小显着减少。
Recent developments in X-ray imaging have resulted in a number of modalities using scanned X-ray beams to expose radiographic film or electronic detector arrays. Among these techniques are those focused on improving scatter rejection by scanning-slit or rotating-wheel techniques. This note outlines a simple variation of the conventional wheel collimator geometry which preserves a constant beam velocity along the length of the scan line and allows a significant reduction in wheel size.
