Phased array ultrasound is a medical imaging technique that uses multiple small ultrasound transducers arranged in a specific pattern. These transducers can be electronically controlled to emit sound waves in different directions, allowing for the creation of detailed images of internal structures, such as organs and tissues. This method is particularly useful for examining the heart and blood vessels. One of the key advantages of phased array ultrasound is its ability to produce real-time images with high resolution. It can also be used in various settings, including cardiology, obstetrics, and emergency medicine, making it a versatile tool for healthcare professionals.
