TECHNOLOGIES FOR DIAGNOSING NEUROLOGICAL OR PSYCHIATRIC ILLNESSES |
| 摘要 |
A technology which enables identifying, via a computer, a vessel in a third image. The third image is obtained from a subtraction of a second image from a first image. The second image and the first image are aligned on an imaging space. The first image is post-contrast. The second image is pre-contrast. The technology enables determining, via the computer, a voxel intensity mean value of a segment of the vessel in the third image. The technology enables obtaining, via the computer, a fourth image from a division of the third image by the voxel intensity mean value. The technology enables applying, via the computer, a filter onto the fourth image. The technology enables generating, via the computer, a filter mask based on the fourth image. |

1. A method comprising:
identifying, via a computer, a vessel in a third image, wherein the third image is obtained from a subtraction of a second image from a first image, wherein the second image and the first image are aligned within an imaging space, wherein the first image is post-contrast, wherein the second image is pre-contrast; determining, via the computer, a voxel intensity mean value of a segment of the vessel in the third image; obtaining, via the computer, a fourth image from a division of the third image by the voxel intensity mean value; applying, via the computer, a filter onto the fourth image; and generating, via the computer, a filter mask based on the fourth image. |
