ANATOMICAL TECHNOLOGIES Mammography and Its Improvements

Technology

Description

Developmental Stage

First FDA Approval

Screen-Film

Mammography

X-rays are sent through the breast tissue. Denser tissue, which is often associated with cancer, absorbs the x-rays and appears as a white region on the film.

Routine clinical use for screening

1969

Computer Aided Detection

Uses computer algorithms to highlight suspicious areas on mammograms for the radiologist to review.

Clinical use for screening

1998

Digital

Mammography

Similar to screen-film mammography except x-rays are recorded in digital format instead of on x-ray film.

Clinical use for screening

2000

Tomosynthesis

A computer assembles information from mammograms taken at several different angles to provide high-resolution cross-sections and three-dimensional images.

Experimental use (clinical prototype)

Diffraction Enhanced Imaging

A synchrotron-based x-ray machine. Integrates two images, one image based on x-ray absorption (e.g., conventional image from an x-ray) and the other based on refraction.
