An automatic quantitative analysis method is developed so as to analyze perfusion cardiovascular images. First the image registration per data set is performed so as to compensate for translation and rotation of the target region of interest over the acquisition time. Next a parameter, for example, a maximum intensity projection, is calculated in order to average out misalignments of the target region of interest within each data set. Finally, parameter registration is performed to calculate the co-ordinate translation matrix between the anatomically corresponding pixels within the target region of interest. The co-ordinate translation matrix can also be used to calculate local perfusion values.
A method of automatically registering anatomically corresponding positions in at least a first image data set (11) and a second image data set (12) that comprise a first and a second series of images, which method includes the steps of:
A method as claimed in one of the preceding claims, in which results of the registration operation (20) on the first parameter (15) relative to the second parameter (16) are used to determine a third parameter (24).
A method as claimed in one of the preceding claims, in which at least one of the registration operations (20) is performed by way of a rigid transformation.
A method as claimed in one of the preceding claims, in which at least one of the registration operations (20) is performed by way of a non-rigid transformation.
