What is the primary component of a mammography system used for imaging?

The primary component of a mammography system used for imaging is the X-ray tube. In mammography, the X-ray tube is specifically designed to produce X-rays that are appropriate for imaging breast tissue. It operates at lower kilovoltage settings compared to standard X-ray machines, which enhances the contrast of soft tissues. This is critical for identifying subtle differences in tissue density, which helps in the detection of abnormalities such as tumors or calcifications.

The X-ray tube emits a focused beam of X-rays that penetrate the breast tissue and create images on a detector or film. This is essential for the effective diagnosis of breast cancers at an early stage. The design of the mammography X-ray tube includes features such as compression paddles to flatten the breast, which further improves image quality by reducing motion blur and scattering of X-rays.

Other options, while related to imaging technologies, do not function as the primary component in a mammography system. Contrast agents are used in certain imaging modalities to enhance visibility of structures but are not a core component of mammography itself. Ultrasound probes are used in breast ultrasound examinations, which serve different diagnostic purposes alongside mammography. CT scanners are advanced imaging modalities that provide cross-sectional images of the body but are not utilized in standard mamm
