METHOD, APPARATUS, AND ARTICLE FOR ULTRASOUND BLOOD FLOW MEASUREMENT |
| 摘要 |
A method includes obtaining first and second ultrasound image data and;computing a coarse transverse flow field by applying an optical flow technique to compare the second ultrasound image data to the first ultrasound image data at a coarse scale. The method further includes computing a fine transverse flow field by applying optical flow technique to compare the second ultrasound image data to the first ultrasound image data at a scale that is finer than the coarse scale and superimposing the fine transverse flow field onto the coarse transverse flow field to form a first combined flow field. |

1. A method comprising:
obtaining first and second ultrasound image data; computing a coarse transverse flow field by applying an optical flow technique to compare the second ultrasound image data to the first ultrasound image data at a coarse scale; computing a fine transverse flow field by applying optical flow technique to compare the second ultrasound image data to the first ultrasound image data at a scale that is finer than the coarse scale; and superimposing the fine transverse flow field onto the coarse transverse flow field to form a first combined flow field. |
