Abstract
An ultrasonic imaging device includes a plurality of ultrasonic transducers arranged in rows and columns. Each transducer has a lower electrode and an upper electrode. In each row, any two neighboring transducers of the row respectively have their lower electrode and their upper electrode connected to each other, or their upper electrode and their lower electrode connected to each other and in each column, any two neighboring transducers in the column respectively have their lower electrode and their upper electrode connected to each other, or their upper electrode and their lower electrode connected to each other.
Claims9
A row-column addressing ultrasonic imaging device comprising a plurality of ultrasonic transducers arranged in rows and columns, each transducer comprising a lower electrode and an upper electrode, wherein:
- in each row, any two neighboring transducers in the row respectively have their lower electrode and their upper electrode connected to each other, or their upper electrode and their lower electrode connected to each other so that, in each row, a row conductor common to all the transducers in the row winds vertically between the transducers in the row, alternately running through the lower and upper electrodes of the transducers in the row;
- and
- in each column, any two neighboring transducers in the column respectively have their lower electrode and their upper electrode connected to each other, or their upper electrode and their lower electrode connected to each other so that, in each column, a column conductor common to all the transducers in the column winds vertically between the transducers in the column, alternately running through the lower and upper electrodes of the transducers in the column.
