Abstract

To avoid problems in communication between the examining physician, the X-ray technician and the diagnosing radiologist, the present invention utilizes adhesive tape having radiopaque material incorporated into it. This tape is for use by the examining physician, to mark the exact location of concern. It will be visualized by the X-ray technician who shoots the film, and will then appear on the processed film to focus the attention of the radiologist to the area deserving closest attention.

Claims

1. A method for the medical examination and radiographic diagnosis of possible fractures or other medical problems, comprising the steps of:

initial examination of the patient;

securing flexible adhesive tape provided with a fine repetitive radiopaque pattern material to the patient'"'"'s skin at the time of the initial examination, to locate critical areas such as tenderness, sensitivity or the entry point for foreign objects, said adhesive tape being of conventional type of medical tape formed of very flexible material provided with a series of evenly spaced unique radiopaque dots or other fine identifiable radiopaque indications to preclude possible confusion with foreign objects in the patient'"'"'s body;

directing X-rays to the critical area of the patient as identified by the adhesive material and the fine radiopaque pattern and forming a visible image from the transmitted X-radiation; and

viewing said visible image wherein the image of the fine radiopaque pattern indicates the areas to which primary attention should be directed;

whereby the original examining physician may identify the critical local area deserving primary attention by subsequent viewers of the X-ray images who may not have had the opportunity of examining the patient.

2. A method as defined in claim 1 wherein said securing step includes securing adhesive material having barium sulfate pigments as the radiopaque material.

3. A method for the medical examination, X-raying, and radiographic diagnosis of possible fractures or other medical problems, comprising the steps of:

initial examination of the patient,

securing flexible adhesive tape provide with a fine radiopaque pattern to the patient'"'"'s skin at the time of the initial examination, to locate critical areas such as tenderness, sensitivity or the entry point for foreign objects, said adhesive tape being of conventional type of medical tape formed of very flexible material provided with a series of evenly spaced unique radiopaque dots or other fine identifiable radiopaque indications to preclude possible confusion with foreign objects in the patient'"'"'s body;

sending the patient to have X-rays taken, with the adhesive tape with fine radiopaque pattern being intact on the skin of the patient to direct the X-ray technician'"'"'s attention to the localized area;

X-raying the localized area identified by the fine radiopaque patterned tape; and

subsequently reviewing the resultant X-rays with the image of the fine radiopaque patterned tape indicating the area of the X-ray to be most clearly examined for diagnosis;

whereby the examining physician may permanently identify the critical local area deserving primary attention by the X-ray technician and the radiologist.

4. A method as defined in claim 3 wherein said securing step includes securing adhesive tape having barium sulfate pigments as the radiopaque material.
