Is breast splint the same as molybdenum target?

It's different. Breast splint and molybdenum target are not the same thing, but two commonly used inspection tools in medical imaging. Mammography press pad is a kind of equipment used for mammography. It is a spreading plate or splint, which is used to flatten the breast so as to show the breast tissue more clearly in mammography. Molybdenum target is an integral part of X-ray emission tube. This is a metal target, which is used to produce X-rays. In mammography, molybdenum targets are often used as X-ray sources for breast imaging.
