Abstract
The present disclosure relates to a system and method for extracting a region of interest. Image data in a first sectional plane may be acquired. The image data in the first sectional plane may include at least one first slice image and one second slice image. A first region of interest (ROI) in the first slice image may be determined. A second ROI in the second slice image may be determined. A first volume of interest (VOI) may be determined based on the first ROI, the second ROI, and characteristic information of the image data in the first sectional plane.
Claims16
A method implemented on at least one machine, each of the at least one machine having at least one processor and one storage, the method comprising:
- acquiring image data generated by a medical imaging device;
- determining, based on the image data, a first volume of interest (VOI);
- performing, based on the first VOI, region growing of a second VOI at a first point in time;
- determining a number of extraction times of a plurality of seed points during the region growing from the first point in time to a second point in time;
- and
- adjusting, based on the number of extraction times of the plurality of seed points, a speed of the region growing of the second VOI by:
- in response to a determination that the number of extraction times of the plurality of seed points is less than or equal to a pre-determined value, decreasing a speed of generating a plurality of new seed points;
- or
- in response to a determination that the number of extraction times of the plurality of seed points is larger than or equal to the pre-determined value, increasing the speed of generating the plurality of new seed points.
A system comprising:
- at least one processor, and
- a storage configured to store instructions, the instructions, when executed by the at least one processor, causing the system to effectuate a method comprising:
- acquiring image data generated by a medical imaging device;
- determining, based on the image data, a first volume of interest (VOI);
- performing, based on the first VOI, region growing of a second VOI at a first point in time;
- determining a number of extraction times of a plurality of seed points during the region growing from the first point in time to a second point in time;
- and
- adjusting, based on the number of extraction times of the plurality of seed points, a speed of the region growing of the second VOI by:
- in response to a determination that the number of extraction times of the plurality of seed points is less than or equal to a pre-determined value, decreasing a speed of generating a plurality of new seed points;
- or
- in response to a determination that the number of extraction times of the plurality of seed points is larger than or equal to the pre-determined value, increasing the speed of generating the plurality of new seed points.
A non-transitory computer readable medium comprising executable instructions that, when executed by at least one processor, cause the at least one processor to effectuate a method comprising:
- acquiring image data generated by a medical imaging device;
- determining, based on the image data, a first volume of interest (VOI);
- performing, based on the first VOI, region growing of a second VOI at a first point in time;
- determining a number of extraction times of a plurality of seed points during the region growing from the first point in time to a second point in time;
- and
- adjusting, based on the number of extraction times of the plurality of seed points, a speed of the region growing of the second VOI by:
- in response to a determination that the number of extraction times of the plurality of seed points is less than or equal to a pre-determined value, decreasing a speed of generating a plurality of new seed points;
- or
- in response to a determination that the number of extraction times of the plurality of seed points is larger than or equal to the pre-determined value, increasing the speed of generating the plurality of new seed points.
