A device, system, and method for volumetric ultrasound imaging is described. The device and system include an array of transducer elements grouped in triangular planar facets and substantially configured in the shape of a hemisphere to form a cup-shaped volumetric imaging region within the cavity of the hemisphere. A plurality of data-acquisition assemblies are connected to the transducers, which are configured to collect ultrasound signals received from the transducers and transmit image data to a network of processors that are configured to construct a volumetric image of an object within the imaging region based on the image data received from the data-acquisition assemblies. A control module includes a firmware module, a low-level operating-system device driver and an application programming interface library for processes ultrasound signals transmitted and received from the array of transducer elements.
