  2. Ultrasonography of chronic venous insufficiency of the legs

    en.wikipedia.org/wiki/Ultrasonography_of_chronic...

    The reflected ultrasound is received by the probe, transformed into an electric impulse as voltage and sent to the engine for signal processing and conversion to an image on the screen. The depth reached by the ultrasound beam is dependent on the frequency of the probe used. The higher the frequency the lesser the depth reached. [9]

    en.wikipedia.org/wiki/Intravascular_ultrasound

    The sound waves are emitted from the catheter tip, are usually in the 20-40 MHz range, and the catheter also receives and conducts the return echo information out to the external computerized ultrasound equipment which constructs and displays a real time ultrasound image of a thin section of the blood vessel currently surrounding the catheter ...

  4. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.

  5. Ultrasound computer tomography - Wikipedia

    en.wikipedia.org/wiki/Ultrasound_computer_tomography

    Ultrasound computer tomography (USCT), sometimes also Ultrasound computed tomography, Ultrasound computerized tomography [1] or just Ultrasound tomography, [2] is a form of medical ultrasound tomography utilizing ultrasound waves as physical phenomenon for imaging. It is mostly in use for soft tissue medical imaging, especially breast imaging ...

  6. Doppler ultrasonography - Wikipedia

    en.wikipedia.org/wiki/Doppler_ultrasonography

    Any sudden changes in direction of blood flow produces audible sounds on the ultrasound machine. [3] In spectral Doppler, the y-axis shows the direction and velocity of the flow. Meanwhile, the x-axis (as known as "baseline") shows the flow over time. The gradient at any point on the waveform would therefore shows the acceleration of the flow ...

    en.wikipedia.org/wiki/Focused_ultrasound

    These procedures generally use lower frequencies than medical diagnostic ultrasound (from 0.7 to 2 MHz), but higher the frequency means lower the focusing energy. HIFU treatment is often guided by MRI. Focused ultrasound may be used to dissolve kidney stones by lithotripsy. Ultrasound may be used for cataract treatment by phacoemulsification.
