2 thg 4, 2017 · Ultrasound images are created by reflected sound waves returning back to the transducer. The nature of the image is based on the properties of different tissues in the body.
Ultrasound images in medical imaging are generated from sound waves reflected from different tissues and organs and converted into electrical signals, which a computer processes to create an image displayed on a screen.
31 thg 3, 2020 · The ultrasound waves (pulses of sound) are sent from the transducer, propagate through different tissues, and then return to the transducer as reflected echoes. The returned echoes are converted back into electrical impulses by the transducer crystals and are further processed to form the ultrasound image presented on the screen.
Principles of how ultrasound imaging works explained without using complicated physics.
22 thg 7, 2025 · Four-dimensional (4D) ultrasound builds upon 3D technology by adding the element of time, creating a moving 3D image. This produces a live video of internal structures, allowing observation of movement, such as a baby yawning or kicking.
14 thg 7, 2024 · Sound waves create images in ultrasound technology through a process involving the transmission and reflection of high-frequency sound waves.
16 thg 7, 2020 · This chapter serves as a basic overview of ultrasound physics and image acquisition. This includes standard machine functionality and transducer manipulation.
The ultrasound transducer acts as both the source and the receiver of the sound waves, unlike the eye which only receives light. The ultrasound image is acquired as a series of lines, while your eye/a camera acquires an image as a grid of pixels.
Ultrasound waves are produced by a transducer, which can both emit ultrasound waves, as well as detect the ultrasound echoes reflected back. In most cases, the active elements in ultrasound transducers are made of special ceramic crystal materials called piezoelectrics.
19 thg 9, 2024 · Ultrasound imaging (sonography) uses high-frequency sound waves to view inside the body. Because ultrasound images are captured in real-time, they can also show movement of …
