Final answer:
Orienting the transducer in different orientations during an ultrasound examination allows for optimal imaging of subcutaneous structures like tendons and organs.
Step-by-step explanation:
Orienting the transducer in radial and antiradial orientations allows for optimal visualization of subcutaneous body structures such as tendons and organs. Ultrasound uses ultrasonic waves which are converted into images that reveal the shape and density of internal structures. By sweeping the directional beam and using multiple ultrasound sources in a phased manner, a computer can construct accurate images from the echoes that represent various positions and depths. This technology is essential in medical imaging, similar to how CT scans provide detailed images using x-rays and MRI machines utilize magnetic fields to generate pictures of internal body structures.
