Study Notes
Ultrasound Transducers
- The essential element of each ultrasound transducer is the piezoelectric crystal, which converts electrical energy into sound waves and vice versa.
Probe Types
- The curved linear probe is suitable for abdominal scans due to its wider depth and deeper penetration.
- The high-frequency linear probe is generally better for imaging superficial structures and vessels, providing high-resolution images.
- The curved array probe has a wider field of view at a lower frequency, making it suitable for specific applications.
Transducer Function
- The main function of an ultrasound transducer is to convert electrical energy into sound waves, transmit them into the body, and convert the reflected echoes back into electrical signals, which are then used to produce images.
