Method and system for image processing and assessment of a state of a heart
One embodiment discloses a computerized method of facilitating cardiac intervention. The method may include inputting patient data and creating a computerized interactive model of a heart based on the patient data. The model may include features. The model may simulate at least one proposed cardiac intervention by adding or deleting features to the model, and determining the effects of the proposed cardiac simulation upon the entire model. Simulations may be repeated to allow the user to determine an optimal cardiac intervention. A template and/or patient specific instrument may be created from the model to use as a guide during the cardiac intervention.
1 . A method of assessing a state of a human heart, comprising:
providing a first set of images of a heart and a second set of images of a heart, wherein the first and second set of images are taken over a first period of time and a second period of time;
dividing the images of the heart from the first and second set into a plurality of regions of the heart for each set, wherein each of the regions corresponds between each of the images from the first and second set;
redividing the plurality of regions of the heart for the first and second set to produce a resampled first set of regions of the heart and a resampled second set of regions of the heart such that the resampled first set and the resampled second set comprise an equivalent predetermined number of regions of the heart;
assessing at least a first property in each region of the heart from the resampled first set;
assessing at least a second property in each region of the heart from the resampled second set; and
comparing a first property of a region of the heart from the resampled first set to a second property of the region of the heart from the resampled second set to assess a third property of the region of the heart.

8 . The method of claim 1 , wherein the predetermined number of regions comprises 16 regions.
9 . The method of claim 1 , wherein the predetermined number of regions comprises 16 regions, and wherein the 16 regions comprises the basal, the mid-wall, and the apical regions of the left ventricle.
10 . The method of claim 1 , wherein the predetermined number of regions comprises 16 regions, wherein the 16 regions comprises the basal, the mid-wall, and the apical regions of the left ventricle, wherein the basal and mid-wall regions comprise 6 equivalently sized regions each, and wherein the apical region comprises 4 equivalently sized regions.
11 . The method of claim 1 , wherein the images are provided to a computer system, and wherein the computer system automatically performs one or more parts of the method.
12 . The method of claim 1 , further comprising creating a model of the heart from one or more of the plurality of images taken at a selected time.
13 . The method of claim 12 , wherein the created model graphically displays the first property, the second property, and/or the third property.
14 . The method of claim 12 , further comprising creating a plurality of models of the heart over the selected period of time.
15 . The method of claim 12 , wherein the model of the heart comprises a three-dimensional model of the heart.
16 . The method of claim 15 , wherein the created model graphically displays the first property, the second property, and/or the third property.
17 . The method of claim 1 , wherein one or more of the regions comprises one or more points.
18 . (canceled)
19 . The method of claim 1 , wherein the selected period of time comprises a cardiac cycle.
20 . A system configured to assess a state of a heart, comprising:
a CPU; and
a system memory coupled to the CPU, wherein the system memory stores one or more computer programs executable by the CPU;
wherein one or more computer programs are executable to:
provide a first set of images of a heart and a second set of images of a heart, wherein the first and second set of images are taken over a first period of time and a second period of time;
divide the images of the heart from the first and second set into a plurality of regions of the heart for each set, wherein each of the regions corresponds between each of the images from the first and second set;
redivide the plurality of regions of the heart for the first and second set to produce a resampled first set of regions of the heart and a resampled second set of regions of the heart such that the resampled first set and the resampled second set comprise an equivalent predetermined number of regions of the heart;
assess at least a first property in each region of the heart from the resampled first set;
assess at least a second property in each region of the heart from the resampled second set; and
compare a first property of a region of the heart from the resampled first set to a second property of the region of the heart from the resampled second set to assess a third property of the region of the heart.
21 . A carrier medium configured to store program instructions, wherein the program instructions are executable to implement a method to assess a state of a heart, comprising:
providing a first set of images of a heart and a second set of images of a heart, wherein the first and second set of images are taken over a first period of time and a second period of time;
dividing the images of the heart from the first and second set into a plurality of regions of the heart for each set, wherein each of the regions corresponds between each of the images from the first and second set;
redividing the plurality of regions of the heart for the first and second set to produce a resampled first set of regions of the heart and a resampled second set of regions of the heart such that the resampled first set and the resampled second set comprise an equivalent predetermined number of regions of the heart;
assessing at least a first property in each region of the heart from the resampled first set;
