CT Rectal Marker

The non-metallic CT Rectal Marker is a flexible tube packed with teflon balls spaced at 1 cm intervals from center to center. The Rectal Marker is used to accurately obtain both the rectum position and magnification by counting the balls. This determines the rectum location relative to the radiation field.

 

An adjustable anus marker can be utilized during CT simulation. The Rectal Marker can be used in the vaginal or as an external marker.
