Coherence and Noise in Ultrasonic Transmission Imaging
Ultrasonic transmission imagingl has improved so far that practical applications in medical diagnosis can be expected for the near future. Especially diffuse, spatially incoherent ultrasound, as described by Havlice et a12, has made image content more reliable. Images of hand or foot displaying tendons and blood vessels are readily available and, at the moment, a first practical application will probably be in orthopedics.
