What type of imaging system is most likely to feature a higher peak kilovoltage (KVP) for breast imaging?

Full-field digital mammography systems utilize a higher peak kilovoltage (KVP) compared to other types of mammography systems to enhance image quality and optimize contrast. Higher KVP levels allow for improved penetration of the x-ray beam through the breast tissue, which is especially beneficial for imaging denser breasts. This capability is crucial because denser breast tissue can absorb lower energy x-rays; therefore, using a higher KVP is essential for obtaining clear and diagnostic images.

In contrast, analog and digital mammography systems typically operate effectively at lower KVP levels since their imaging techniques do not require the same degree of penetration as full-field digital systems. Portable systems might also utilize lower KVP levels to maintain portability and ease of use, as they are designed for accessibility rather than optimized image quality. Full-field digital mammography's ability to work at higher KVP thus facilitates better visualization of breast structures, making it the preferred choice in modern mammography practice.
