Transmission in ultrasound physics refers specifically to the passing of ultrasound waves through a medium. This process is essential for effective imaging, as it allows sound waves generated by the transducer to travel through tissues and fluids, reaching various depths within the body.

When ultrasound waves encounter different tissues or materials, a portion of the waves is transmitted while other portions may be absorbed, scattered, or reflected. The transmitted waves are what provide valuable information to the imaging system, as they continue through the media and may be reflected back to the transducer at interfaces with different acoustic properties. The ability of ultrasound waves to transmit allows for the generation of images based on the varying echoes that are returned.

This fundamental concept of transmission is crucial for understanding how ultrasound technology captures images of internal structures, which is why it is a key term in ultrasound physics.
