Transducers used in image production typically require a wide bandwidth to accurately represent the various frequencies present in the tissue being imaged. A low Q-factor and wide bandwidth are ideal for imaging transducers as they allow for a broad range of frequencies to be transmitted and received, resulting in high image resolution and quality. Therefore, the correct answer is B.

High Q-factor, narrow bandwidth (Option D) implies a high quality factor and the ability to resonate at a single frequency. Although this characteristic may be suitable for specific applications like Doppler imaging, it is not ideal for general imaging purposes where a broad range of frequencies is required.

Low Q-factor, narrow bandwidth (Option C) does not provide the necessary range of frequencies required for detailed imaging as it limits the transducer's ability to transmit and receive a wide spectrum of frequencies.

High Q-factor, wide bandwidth (Option A) contradicts the requirements for imaging transducers. While a high Q-factor implies efficient energy transfer, a wide bandwidth is crucial for capturing a broad range of frequencies in imaging.
