    Abstract: Described herein are arrays of piezoelectric ultrasound elements. The piezoelectric ultrasound elements may be arranged in a checkerboard pattern. The piezoelectric ultrasound elements in one column may be shifted along the vertical dimension of the array with respect to piezoelectric ultrasound elements in an adjacent column. A piezoelectric ultrasound element in one column may be coupled to a different circuit than all other piezoelectric ultrasound elements in the column. The circuit may be, for example, an analog-to-digital converter or a circuit configured to transmit ultrasound signals from the array. Each piezoelectric ultrasound element in a column may be configured so that it can operate at a different frequency from each of the other piezoelectric ultrasound elements in the column. There array may include at least 1,000 piezoelectric ultrasound elements. The array may be monolithically integrated with a substrate comprising different circuits for each piezoelectric ultrasound element in the array.

    Abstract: Ultrasound devices are described. The ultrasound devices may be flexibly configured to output a certain number of multilines per channel of ultrasound data and to process certain channels of ultrasound data per processing cycle. The ultrasound device may then be configured to either output more multilines per channel and process fewer channels per processing cycle, or output fewer multilines per channel and process more channels per processing cycle. In other words, the circuitry may be configured to change to a configuration with increased resolution and increased processing time or to a configuration with decreased resolution and decreased processing time.
