20080262353 | METHOD AND APPARATUS FOR FAST VOLUME RENDERING OF 3D ULTRASOUND IMAGE - The invention provides a method and apparatus for fast volume rendering of 3D ultrasound image, comprising a dividing step, a calculating step, a determining step, a morphological closing operation step and a filling step, wherein each flat grid can be entirely filled by obtaining gray-scale values for all pixels inside the grid through interpolating; for the non-flat grid, the steps of dividing, calculating, determining and filling are performed repeatedly until the non-flat grid is subdivided into atomic grids to calculate gray-scale values for remaining pixels by projection. As the method can be finished in the rear end, no difficulty occurs in the implementation, and no process for being adapted to previous frames is required. Therefore, the method can improve the rendering speed effectively without degrading the quality of image to put 3D ultrasound imaging to the best use. | 10-23-2008 |
20080262355 | METHOD AND APPARATUS FOR FAST 3D ULTRASOUND IMAGING - The present invention provides a method and apparatus for fast 3D ultrasound imaging. The method comprises data acquisition, desired data selection, data smoothing, table construction, ray casting, table look-up, ray synthesis and final result output. The apparatus comprises an acquisition module, a selection module, a smoothing module, a construction module, a ray casting module, a table look-up module, a synthesis module and an output module. The present invention can avoid a huge amount of unnecessary reconstruction calculations by smoothing preprocessing and constructing the reconstruction table and the gradient table as well as transforming coordinates of the points where necessary. The present invention has greater practical applicability, because the existing imaging technology demands that the radius for rotating the probe be identical to the radius of the probe. | 10-23-2008 |
20110129137 | METHODS AND SYSTEMS FOR DEFINING A VOI IN AN ULTRASOUND IMAGING SPACE - An ultrasound imaging system provides for defining a VOI in an ultrasound imaging space. The system defines an initial frame of the VOI in the ultrasound imaging space, receives a selection of at least one reference point at an arbitrary location in the ultrasound imaging space, creates at least one curved surface using at least one element of the initial frame and the at least one reference point, and then creates VOI based on the curved surface in the ultrasound imaging space. | 06-02-2011 |

20130303913 | THREE-DIMENSIONAL ULTRASONIC IMAGING METHODS AND SYSTEMS - A method for three-dimensional ultrasonic imaging conducting a first group of line scans on a scanning object at a first group of scanning positions; receiving echo signals from the first group of line scans, and acquiring a first group of scanning line data; carrying out a second group of line scans on the scanning object at a second group of scanning positions; receiving echo signals from the second group of line scans and acquiring a second group of scanning line data; and acquiring a three-dimensional image of the scanning object according to scanning data comprising the first group of scanning line data and the second group of scanning line data; the scanning positions in the second group of scanning positions are shifted by a first distance along a direction parallel with a frame scanning direction relative to the scanning position in the first group of scanning positions corresponding to the scanning position, allowing an increase of joint line space without changing the independent line space, thus the imaging quality is improved without reducing the three-dimensional imaging speed. | 11-14-2013 |
