Abstract
An ultrasound probe can detect flaws in an object in a non-destructive manner. The probe includes a row-column addressed (RCA) array with a plurality of row and column electrodes. The row and column electrodes are configurable to have at least four states: 1) a transmission state, 2) a reception state, 3) a ground state, and 4) a high impedance state. The probe also includes a control circuit to operate the RCA array in different transmission and reception configurations.
