GENERATION OF MASK AND CONTRAST IMAGE DATA IN A CONTINUOUS ACQUISITION

摘要

The present disclosure relates various approaches by which mask and contrast projection data may be acquired using a continuous projection acquisition process, without an interruption in acquisition or resetting of the system between the acquisition of the mask projection data and the contrast projection data. In certain implementations, the approaches described herein may be employed with a single-plane or multi-plane tomosynthesis system.

主权项

1. An imaging method, comprising:
continuously moving an X-ray source and an X-ray detector of a tomographic imaging system in a periodic motion along a limited angular range with respect to an imaged volume, wherein each period of motion comprises an orbit of the X-ray source and the X-ray detector with respect to the imaged volume; and acquiring a first projection dataset using the X-ray source and the X-ray detector; while the X-ray source and the X-ray detector continue to move after acquisition of the first projection dataset, acquiring a second projection dataset; and reconstructing at least one 3D subtracted image using the first projection dataset and the second projection dataset.
