What is the primary function of a transducer in biomedical equipment?

The primary function of a transducer in biomedical equipment is to convert one type of energy into another. In the context of medical imaging and monitoring, transducers play a crucial role by transforming physical phenomena into electrical signals that can be processed and interpreted. For example, in ultrasound machines, the transducer converts electrical energy into sound waves, which then travel through the body and are reflected back, allowing the system to produce images of internal structures. Conversely, it also converts returning sound waves back into electrical signals for analysis. This energy transformation capability is fundamental to various biomedical applications, making the selection of this answer pertinent.
