Abstract: The present disclosure relates to the iterative reconstruction of projection data. In certain embodiments, the iterative reconstruction is a multi-stage iterative reconstruction in which different feature are selectively emphasized at different stages. Selective emphasis at different stages may be accomplished by differentially handling two or more decompositions of an input image at certain iterations and/or by differently processing certain features with respect to each stage.

Abstract: 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.

Abstract: In accordance with one aspect of the present system, a dual energy X-ray imaging system includes a communication module configured to receive a pre-shot image from a detection circuitry and receive one or more pre-shot parameters from a source controller of the dual energy X-ray imaging system. The dual energy X-ray imaging system further includes an analysis module configured to determine one or more image characteristics of the pre-shot image. The dual energy X-ray imaging system further includes a determination module configured to calculate a first and a second set of main-shot parameters based on the one or more pre-shot parameters and the one or more image characteristics of the pre-shot image. The determination module is further configured to send the one or more main-shot parameters to the source controller of the dual energy X-ray imaging system.

Abstract: A method for X-ray imaging includes determining one or more pre-shot parameters corresponding to a region of interest in a subject based on an optical image of the region of interest obtained from an optical sensor. The method further includes controlling an X-ray device to generate a pre-shot X-ray image using a first X-ray dosage, based on the one or more-pre-shot parameters. The method also includes determining at least one main-shot parameter based on the pre-shot X-ray image. The method includes controlling the X-ray device to generate a main-shot X-ray image using a second X-ray dosage greater than the first X-ray dosage, based on the at least one main-shot parameter.

Abstract: Approaches for assessing hemodynamic characteristics for an organ of interest are related. In one implementation, a fluid dynamics model may be provided with data derived from an anatomic imaging modality and blood flow information derived by ultrasound to derive the desired hemodynamic characteristics. In one such implementation, a fractional flow reserve is estimated.

Abstract: Disclosed aspects relate to the acquisition and processing of projection data using temporal characteristics of the imaged volume, such as the uptake and clearance of a contrast agent within the volume. Such temporal aspects may be used in the acquisition process, such as to differentially acquire images based on the propagation of the contrast agent. In addition, such temporal aspects may be used in the processing of projection data to generate differential projections (e.g., first or second order subtraction projections), compound projections synthesized using the absolute or relative maximum opacity values observed over time for a region of interest, or interpolated projections synthesized using observed opacity values at known or fixed time intervals and a derived peak opacity time.
Abstract translation: 公开的方面涉及使用成像体积的时间特征（例如体积内的造影剂的摄取和清除）来获取和处理投影数据。 这样的时间方面可以用于采集过程中，例如基于造影剂的传播来差异地获取图像。 此外，这些时间方面可以用于投影数据的处理以产生差分投影（例如，一阶或二阶减法投影），使用随时间观察感兴趣区域的绝对或相对最大不透明度值合成的复合投影， 或使用在已知或固定时间间隔处观察到的不透明度值合成的内插投影和衍生的峰值不透明度时间。
