Last time I had a mammogram, they used these nice little pads on the glass. When she was done, she threw it in the trash, and I hauled it out and asked if I could have it. Nice cushion on one side, and sticky on the other. It's about 8 x 10, and fits perfect for my foot pedal. No more traveling across the rug. See if your Woman's Health Center uses these. The nurse said it wasn't the first time someone asked for them.
