Abstract
Magnetic Resonance Angiography (MRA) method and apparatus for determining an angiogram, in the form of a two-dimensional array of pixel intensities, from time-of-flight or phase contrast MRA volumetric image data utilizes a weighted sum, pixel by pixel, of integration projection (IP) and maximum intensity projection (MIP) 2D pixel arrays formed in the same viewing direction. The forming of the integration projection pixel array is preceded by optional background suppression and optional application of a depth cueing intensity weighting function varying along the viewing direction. The background suppression procedure contains a non-linear unsharp filtering portion followed by an intensity thresholding step.
