Multiple users are supported with an ultrasound server. Tiling of images may be used to limit transmission and/or bandwidth. By transmitting parts of images that change and avoiding transmission of other parts, wireless and processing bandwidth may be optimized. On the server side, separate instances are used for scanning each patient or for each of the multiple transducer probes being used. Dynamic assignment of shared resources based on use of the transducer probes may provide further optimization. From an overall perspective, the server may beamform from data received by a transducer probe based on controls routed from a separate tablet used as a display and user input.
