Sinus - Video Lesson

In this view, we will be demonstrating the lateral sinuses. The lateral horizontal beam sinuses should be performed with the patient standing or sitting at the upright buccy. With a forty inch source to image distance and no tube angulation. For lateral views of the sinuses, We place the affected side against the board. My patient is standing upright. His left side is against the board. This places the mid sagittal plane parallel to the IR. It places the IOML perpendicular to the front edge of the IR. And it places the inter pupillary line perpendicular to the IR. Forty inches SID. There is no angle on the tube. The central ray is halfway between the outer canvas and the EAM, but a little closer to the outer canvas.
