ABSTRACT:
Tape which is used to mark the location of arterial blockage or other medical problems on x-ray film. The tape has a T-shaped configuration and includes a flat main body and a rib projecting from the main body. The main body of the tape strip has an adhesive layer on one side which is initially covered by a cover strip. When the cover strip is removed, the strip can be adhesively attached to a patient who is to be x-rayed. The rib has graduation marks that are opaque to x-rays and are thus reproduced on the x-ray film to correlate the location of the medical problem with the marks during subsequent treatment. The rib can be folded flatly against the main body of the tape strip and held adhesively in that position so that the graduation marks are useful when x-rays are taken in two different dimensions.
