Abstract
An array of micromachined ultrasonic transducers (MUTs). The array has first and second rows, the MUTs in the first row being equally spaced by a horizontal pitch in a horizontal direction, the MUTs in the second row being equally spaced by the horizontal pitch in the horizontal direction. The MUTs in the second row are shifted along the horizontal direction by a first horizontal distance relative to the MUTs in the first row and shifted along a vertical direction by a first vertical distance relative to the MUTs in the first row. The first horizontal distance is greater than zero and less than the horizontal pitch. The first vertical distance ranges from one tenth of a horizontal width of a MUT to a half of a vertical height of a MUT.
