Automated mammography apparatus for mass screening

摘要

Apparatus for X-raying the breasts of women wherein the X-ray images are sequentially recorded on a continuous roll of film which is advanced between X-ray exposures by an amount dependent on breast size from a supply spool to a take-up spool and which is pressed against a phosphor X-ray intensifying screen during exposures by a vacuum-actuated pressure plate. Provision is included for X-raying a large breast in portions without subjecting any single portion of the breast to X-radiation more than once.
