​Ultrasound Transducer Types Explained: Linear, Convex, Phased Array, and Special Probes (Radiology Physics)
​Detailed Description
​Master the different types of Ultrasound Transducers! This comprehensive lecture covers the features, frequency ranges, beam shapes, and clinical applications of modern Ultrasound probes, along with an overview of older mechanical systems.
​Understanding the right transducer for the job is essential for obtaining high-quality diagnostic images.
​Key Transducer Types and Topics Covered:
​Mechanical vs. Electrical Scanning: The fundamental difference between older and modern systems [01:03].
​Linear Transducer (High Frequency): Learn its rectangular beam shape, high frequency (5-15 MHz), and applications in Vascular, Thyroid, Breast, and MSK imaging [08:31].
​Phased Array Transducer (Medium Frequency): Discover its compact size, cone-shaped beam, the concept of Beam Steering, and its primary use in Echocardiography (Cardiac) and Intercostal scanning [10:26].
​Curvilinear / Convex Transducer (Low Frequency): The most common probe, featuring a curved surface, sector-shaped beam, low frequency (2-5 MHz), and use for Abdominal, Pelvic, and Obstetric imaging [14:45].
​Specialized Transducers: A look at Intraoperative and Endocavitary probes (Transvaginal/Transrectal) [17:08].
​3D and 4D Transducers: Discussing their role in advanced imaging, particularly in Obstetrics [18:11].
​PC PNDT Act Mention: A brief note on the ban on sex determination via ultrasound in India [18:51].
