Applying MRI-Safe Marker Patches, Electrode Patches, and Rulers for Electromyometrial Imaging

To begin print the MRI and electrode patch templates on paper. Cut 22 rectangular and four square patches from the clear vinyl sheet. Similarly, cut 44 rectangular and eight square patches from the silicone rubber sheet, and from the color silicone rubber sheet.

To make MRI safe marker patches overlay a template with a clear vinyl patch, and glue MRI safe markers to the vinyl patch at the centers of the circles, which represent the electrode holder cavities on the template. Make electrode patches by labeling the circle locations on the silicone rubber patches. And punch holes at those locations using a punch set with a diameter of eight millimeters.

Also punch the holes in the transparent material. Align the circumference of the punch toll with the circumference of the electrode holder cavity, and attach electrode holders over each hole with double-sided adhesive collars. Install the X-ring into the cavity on top of the electrode holder.

Cover the holder with the color-coded silicone sheet and insert the pin type active electrode through the X-ring into the holder. Apply three strips of medical grade, double-sided tape to the electrode patch between the rows of electrodes along the long edge of the patch. Cut six measuring tapes at their 30 centimeter marks and retain the top section from zero to 30 centimeters.

To make a horizontal ruler glue the zero centimeter edges of two measuring tapes to a long piece of vinyl strip with a gap in the width of the tape. Apply double-sided adhesive tape to each ruler.
