发明名称 Image marker device
摘要 A marker device for body scanning which permits the location of internal parts of a patient's body by reference to image reference points produced by marks on the device attached to the surface of the patient's skin during the scanning process. The device comprises a flexible tape which includes a substrate with marks, usually lines, thereon, the substrate being relatively transparent to the scanning waves, while the reference lines are relatively opaque with respect thereto. The substrate is conveniently formed from plastic, while the reference lines are advantageously metallic in character, preferably copper strips. The substrate is ordinarily coated with a pressure sensitive adhesive to allow its attachment to the patients outer skin, and it may be perforated with holes to accommodate insertion of biopsy needles.
