  • Patent number: 9679378
    Abstract: The present invention relates to a method for generating a risk map indicating predicted voxel-by-voxel probability of tissue infarction for a set of voxels, the method comprising the steps of, receiving for each voxel a first value (x) corresponding to a set of tissue marker values and generating the risk map, using a statistical model based on data from a group of subjects, and a stochastic variable, wherein the statistical model also comprises a second value (zi), being based on the stochastic variable, such as the second value modelling non-measured values. The invention may be seen as advantageous since it acknowledges subject variability in probability of tissue infarction on a voxel-by-voxel basis by taking non-measured values into account, which in turn may enable providing more reliable estimates of probability of infarction.

  • Patent number: 9036878
    Abstract: The present invention relates to a method for estimating a measure of a penumbra size of a penumbra in biological tissue wherein first and second images obtained respectively by perfusion weighted imaging (PWI) and diffusion weighted imaging (DWI) are analyzed, and wherein the analysis of the first image includes application of a level set method, and the analysis of the second image includes application of a grayscale morphological operation. In a further embodiment of the invention, a connected component labeling algorithm maybe applied on any one of the first and second image. The invention further relates to a system, a computer program product and use of a corresponding method.

  • Publication number: 20140039320
    Abstract: The present invention relates to an ultrasonic system for measuring a micro-vascular flow distribution of a tissue portion of a mammal comprising an ultrasonic transducer (101) arranged for measuring a first indicator (MTT) for the blood flow through a capillary bed in the tissue portion, and arranged for measuring a second indicator of heterogeneity (CTTH, ?) of the blood flow in said capillary bed, and a processor (110) arranged for using the first (MTT) and the second (?) indicator to estimate an extraction capacity (EC) of a substance from the blood in said capillary bed.
