For ultrasound imaging using a matrix transducer, interconnects or switches are provided to allow sub-arrays forming a 1D array, such as with sub-arrays one element wide with the maximum number of elements in elevation. Where groups are used to limit the switches and available system channels per group, an extra switch may connect between elements of different groups through a group output to extend a sub-array across groups. To further limit the number of switches, the group may be sub-divided where different combinations of sub-groups are connectable with different combinations of the system channels for the group.

For volume ultrasound imaging, the view direction for rendering a volume image is used. In one approach, imaging parameters for acquiring the volume data prior to rendering are set based on the view direction. For the resolution example, the data for imaging is acquired with the resolution in a view plane greater than resolution along the ray tracing direction. In another approach, sets of data representing a volume are acquired or formed with different settings. The sets are weighted based on the view direction and combined. For the resolution example, an image rendered from the combined data may have greater resolution in the view plane where the set of data with greater resolution in that view plane is weighted more in the combination.
