Click to ViewUltrasound imaging encompasses a wide range of imaging modes and techniques that utilize the interaction of sound waves with living tissues to produce an image of the tissues or, in the case of Doppler-based modes, determine a velocity of a moving tissue, primarily blood. Ultrasound imaging is a versatile, well-established, and widely used diagnostic tool in human and veterinary medicine. Its diagnostic applications include noninvasive imaging to characterize the structure, and in some applications the function, of target organs or masses, minimally invasive endocavity imaging with transesophageal and transrectal probes, and invasive imaging with intravascular probes. the term "ultrasonic" applied to sound refers to anything above the frequencies of audible sound, and nominally includes anything over 20,000 Hz.Frequencies used for medical diagnostic ultrasound scans extend to 10 MHz and beyond.

  Working Principles
Click to ViewUltrasound refers to sound waves that are not detectable by the human ear with frequencies greater than 20,000 cycles/sec (Hz). Diagnostic ultrasound commonly uses frequencies between 2 and 15 MHz (10 6 cycles/sec). Intravascular transducers commonly use frequencies up to 30 MHz, and ultrasound biomicroscopy systems with transducers using frequencies up to 100 MHz have been reported ( Foster et. al 2000 ; Turnbull et al. 1995 ). At these frequencies, sound waves are transmitted though soft tissue relative to the acoustic impedance of each tissue. The acoustic impedance of a particular tissue is the product of the transmission velocity of sound and the tissue density. The transmission velocity in most soft tissues and blood is nearly uniform at 1540 m/sec ( Merritt 1998 ). Therefore, the acoustic impedance of most soft tissue is primarily a function of the tissue density. When two tissues with different densities are located next to each other, an acoustic impedance mismatch is created and sound waves are reflected by the mismatch. The greater the acoustic mismatch or difference in tissue densities, the more sound waves are reflected and returned to the transducer. Areas with relatively large tissue density differences, and hence more reflected sound waves, are generally seen as brighter areas on the final image. As a result of these properties, ultrasound imaging is best suited for soft tissue imaging and is often limited by bone- and gas-filled structures. Sound is transmitted rapidly through bone tissue. Conversely, sound is poorly transmitted through air and airfilled structures. The large acoustic impedance mismatch that occurs at bone and gas interfaces with soft tissue causes the majority of sound waves to be reflected. This large reflection decreases sound wave penetration into deeper tissues and can cause imaging artifacts. Despite this limitation, specialized techniques have been developed to perform transcranial Doppler imaging of the cerebral vasculature in humans and dogs ( Seidel et al. 2000 ).

  Applications
  User Instructions
The application of noninvasive ultrasound imaging in research, and particularly the imaging of rats and mice, represents both a significant refinement and an advance in research techniques. As a refinement in research technique, ultrasound imaging can replace more invasive techniques that cause pain and distress.
