Cardiac perfusion analysis
First Claim
1. A method of analyzing a quantity indicative of blood perfusion through a myocardium by analyzing a varying quantity which furnishes an easy reference rendition of the variations of the quantity, the quantity having temporal and spatial variations, including:
- obtaining a multidimensional output data array, the multidimensional output data array comprising array positions arranged along at least a first data-axis and a second data-axis; and
receiving with a processor values corresponding to the quantity indicative of blood perfusion through tissue based on time series perfusion images generated from image data acquired by a tomographic imaging system;
wherein first values corresponding to the quantity at substantially a same instant in time are mapped by the processor to respective positions in the multidimensional output data array at equal positions along the first data-axis, and second values corresponding to the quantity at substantially a same spatial position are mapped by the processor to respective positions in the multidimensional output data array at equal positions along the second data-axis.

Abstract
In a method of analyzing a quantity having temporal and spatial variations a multidimensional output data array is formed. The multidimensional output data array comprises array positions arranged along at least a first data-axis and a second data-axis, such as a spatial axis and a temporal axis. Values of the quantity are entered in the multidimensional output data array. Values of the quantity at substantially the same instant are entered at respective positions in the multidimensional output data array at equal positions along the first data-axis. Values of the quantity at substantially the same spatial position are entered at respective positions in the multidimensional output data array at equal positions along the second data-axis.
