Abstract: The present disclosure relates to the identification and tracking of a navigational instrument (e.g., a needle) in three-dimensions, with substantially real-time image updates of the instrument and updates of the tissue at an equal or lower rate. In certain embodiments, the images are acquired using a C-arm tomosynthesis system configured to move the X-ray source and detector in respective planes above and below the patient.

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。

Abstract: A system for imaging includes a gantry movable relative to a subject. A source is configured to emit radiation during an imaging procedure. A detector is configured to receive attenuated radiation from the source during an imaging procedure, at least one of the source and the detector movably secured to the gantry by an adjustable joint. An imaging controller is operably connected to at least the gantry and to the adjustable joint, wherein the gantry controller receives a priori patient information and imaging system geometry information, the imaging controller determines an imaging geometry and operates the gantry and the adjustable joint to vary a source to image-receptor distance (SID) according to the imaging geometry.
