Abstract

A radiation therapy skin marking device which may be used to delineate a radiation therapy portal area on a patient's skin surface. The device includes a set of radiation therapy skin markers which are releasably attached to a backing liner and include an adhesive surface such that the markers may be releasably attached to a patient's skin surface. The markers include ink-printed lines on the adhesive surface so as to facilitate radiation therapy treatments by more obviously defining a radiation therapy portal area. Ink is transferred onto the skin surface from the adhesive surface by depositing it onto the skin or by absorption into the skin so that the marking lines are delineated on the skin surface when the markers are detached. The markers include various shapes including, for example, a marker of substantially circular shape with a ninety degree wedge cut therefrom such that the marker may be used to outline a ninety degree corner and a marker of substantially circular shape with a circular cut-out center such that the marker is defined by a circular outer edge and a circular inner edge both of which circular edges share a common center point.
