Abstract: An imaging system, such as a DBT system, capable of providing an operator of the system with information concerning the location, magnitude and direction of motion detected by the system during performance of the scan to enhance image processing. The imaging system provides the motion information to the operator directly in conjunction with the images processed by the imaging system thereby providing the operator with sufficient information for decisions regarding the need for additional images for completing the scan with the imaging system before the patient is discharged, or even before the breast is decompressed.

Abstract: An X-ray source transmits X-rays through a subject and a detector receives the X-ray energy after having passed through the subject. A processing system generates a pre-shot image of the subject using low energy X-ray intensity from the X-ray source and determines a plurality of acquisition parameters for a main scan of the subject based on the pre-shot image. A saturation time of the detector for the corresponding acquisition parameters is determined based on detector calibration data and to determine a number of time frames required to reach the targeted dose based on the saturation time. An X-ray dosage level of the subject is then applied using the X-ray source based on the number of time frames and to generate the image of the subject based on the detected X-ray energy at the X-ray detector for the applied X-ray dosage level.
