An ultrasound system and related method for forming 2D C-scan images and/or collecting 3D image data from 2D transducer arrays. The system including in part a 2D transducer array of elements (50) transmit voltage generation means , (51) for each element a memory buffer (56) with or part of channels for each element, and a receive beamformer (58). On a time serial or sequential basis several times for each line of firing, the contents of the per element memory buffer are read into the beamformer with different focusing values for each buffer reading cycle. In this way, the beamformer can calculate beamformed image values for multiple points per line firing cycle-or per each line of …

Why it's free to use
- Filed January 15, 2004 and granted December 24, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 15, 2024.
