A computer implemented method for dynamic angiographic imaging including: obtaining image data comprising a plurality of corresponding images capturing at least a portion of both an increase phase and a decline phase of a contrast agent in a blood vessel of interest; generating at least one time-enhancement curve of the contrast agent based on the image data; determining a blood flow characteristic in the blood vessel of interest based on the time-enhancement curve. Systems for implementing the method and computer readable media incorporating the method are also described.

Dynamic angiographic imaging

Described herein is a head cooling system comprising: a source of compressed breathable gas; a vortex tube comprising an inlet, a hot gas outlet and a cold gas outlet, the inlet operably connected to the source of compressed breathable gas; and an interface for delivering cooled gas to a nasopharyngeal cavity in fluid communication with the cold gas outlet. The head cooling system may be used in a method to reduce neurodegeneration in a subject, for example neurodegeneration from ischemia, anoxia, cardiac arrest, trauma or neurodegenerative disease. The head cooling system may also be used in a method to prophylactically protect a subject at risk of neurodegeneration, for example neurodegeneration from ischemia, anoxia, cardiac arrest, trauma or neurodegenerative disease.

Mammalian head cooling system and method

A system and method of acquiring x-ray data, comprising: acquiring a series of x-ray data for generating at least one x-ray image using an x-ray detector to receive x-ray beams from an x-ray source, wherein an object being imaged is displaced along an axis, the axis extending perpendicularly through a plane defined by the x-ray beams, wherein the displacement occurs at, at least one of a constant, accelerating, and decelerating rates; varying the rate of displacement thus enabling the x-ray detector to acquire data for at least one x-ray image during accelerating or decelerating displacement; and employing current modulation.
