Abstract: Perfusion angiography combined with photoplethysmography imaging for peripheral vascular disease assessment A device (13) and method for performing perfusion imaging receive image sequences that are acquired simultaneously by an X-ray imaging apparatus (2) and by a photoplethysmography imaging apparatus (3). When temporally aligned, changes in the perfusion states of a perfused organic tissue over time are extracted from the two image sequences and an image is generated for display on a display unit (5) which indicates the changes in the perfusion states at various locations of the perfused organ tissue, thereby capturing both deep organ tissue and superficial organ tissue perfusion properties. A diminution in an image signal strength in the photoplethysmography images caused by a passage of a bolus comprising a previously administered contrast agent (10) can be used to align the two concurrently acquired image sequences in time.

Abstract: Even when imaging is aborted, data collected so far is utilized in image reconstruction, thereby enhancing examination efficiency. A certain priority imaging data available for image reconstruction by a fast-imaging method is determined, when collecting k-space data according to a predetermined imaging method. If collection of the certain priority imaging data is completed when imaging is aborted, imaging reconstruction is executed using the priority imaging data. The priority imaging data is determined based on a relationship between the imaging method under execution, and the fast-imaging method underlying determination of the priority imaging data.

Abstract: Method and systems are provided for reliable, convenient, self-administered, and cost-effective determination of central venous pressure. The noninvasive method and apparatus use changes in transmural pressure to create detectable changes in peripheral venous vascular volume for the determination of central venous pressure. Transmural pressure changes can be manifested by intravascular or extravascular pressure changes. The system is noninvasive and uses optical measurements of venous volume in the presence of transmural pressure changes. The relationship between the transmural pressure change and the change in vascular venous volume is combined with anatomical measurements to determine the central venous pressure of the subject. Central venous pressure can be used to determine hemodynamic status of the subject to include fluid overload in the heart failure patient.
