Abstract
An apparatus and method are provided for obtaining x-ray tomosynthesis data desirable for mammography. The apparatus operates in conjunction with gravity to quickly and smoothly move an x-ray source through a plurality of positions relative to a stationary digital detector and a patient's breast to obtain a plurality x-ray images of the patient's breast which can then be processed for examination by a physician or radiologist. In one embodiment, an actuator such as a hydraulic system is operably connectable to the radiation source to controllably allow the radiation source to move under the influence of gravity from an elevated position to a lower position relative to the digital detector.
