Abstract: A system and method are provided for generating time resolved series of angiographic volume data having flow information integrated therewith. The method includes generating a series of 3D time-resolved vascular volumes from time resolved x-ray projection data and calculating blood velocity in the vascular volumes x-ray projection data to determine a rate of change of calculated contrast material arrival time at positions along the vascular volumes. The method also includes displaying the 3D time-resolved vascular volumes with a graphical indication of blood velocity in the vascular volumes.

Abstract: A system and method are provided for generating time resolved series of angiographic volume data having flow information. The system and method are configured to receive angiographic volume data acquired from a subject having received a dose of a contrast agent using an imaging system and process the angiographic volume data to generate angiographic volume images. The angiographic volume data is processed to derive flow information by determining a distance between two points along a vessel in the angiographic volume images and determining a phase at each of the two points along the vessel in the angiographic volume images. A flow direction or a velocity of flow within the vessel is determined using the distance between the two points along the vessel and the phase at each of the two points along the vessel.

Abstract: In an apparatus and method for treating an aneurysm, a flow control member is positioned within a blood vessel at least in part upstream of an aneurysm and extending radially inward of the blood vessel wall into the flow path of blood flowing within the blood vessel. The flow control member alters the blood flow path within the blood vessel upstream of the aneurysm to inhibit blood flow to the aneurysm. A retention member may be positioned within the blood vessel at least in part upstream from the aneurysm and having an outer surface engageable with the blood vessel wall. In such an instance, the flow control member is retained by the retention member and extends radially inward of the blood vessel wall upstream from the aneurysm.

Abstract: A method for generating time-resolved 3D medical images of a subject by imparting temporal information from a time-series of 2D medical images into 3D images of the subject. Generally speaking, this is achieved by acquiring image data using a medical imaging system, generating a time-series of 2D images of a ROI from at least a portion of the acquired image data, reconstructing a 3D image substantially without temporal resolution from the acquired image data, and selectively combining the time series of 2D images with the 3D image. Selective combination typically involves registering frames of the time-series of 2D images with the 3D image, projecting pixel values from the 2D image frames “into” the 3D image, and weighting the 3D image with the projected pixel values for each frame of the time-series of 2D images.

Abstract: A method is disclosed for producing a computed tomographic image of a subject, the method including: using a radiation source and detector, obtaining radiation transmission information relating to a region of interest in the subject; using the source and detector; obtaining a series of projection images of the region of interest. Each projection image is obtained by: directing an imaging beam of radiation from the source through the region of interest onto the detector along a respective direction; the detector having a detection area.
