If the crystal diameter increases, the ERA will

Explanation:
The effective radiating area (ERA) is essentially the portion of the transducer face that emits ultrasound. When the crystal diameter increases, the emitting surface becomes larger, so the ERA grows as well. A bigger ERA means you can treat a larger area of tissue at once, though the intensity per unit area will drop if the total power remains the same (you’d need to increase power to keep the same intensity). In short, increasing the crystal diameter increases the ERA.
