For a biopsy guided by contrast-enhanced x-ray imaging, a breast imaging system may image a patient's breast subsequent to injection of contrast agent to locate a site for biopsy and / or position a biopsy device relative to the site. Once a tissue specimen is removed from the site for diagnostic evaluation, a confirmation that the specimen was removed from an intended area of interest for biopsy is performed using the systems and methods described herein.

The present invention discloses a system and method for improving image acquisition of multiple motion pulse X-ray source tomosynthesis imaging devices by generating ECG waveform data using an electrocardiogram (ECG) device. Once a representative cardiac cycle is determined, the system will acquire images only during the resting period of the heartbeat.
