  2. Face hallucination - Wikipedia

    en.wikipedia.org/wiki/Face_hallucination

    Image superresolution is a class of techniques that enhance the resolution of an image using a set of low resolution images. The main difference between both techniques is that face hallucination is the super-resolution for face images and always employs typical face priors with strong cohesion to face domain concept.

  3. Focused ultrasound - Wikipedia

    These techniques are known as Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) [31] [32] and Ultrasound guided Focused Ultrasound Surgery (USgFUS) respectively. [ 1 ] [ 33 ] MRgFUS is a 3D imaging technique which features high soft tissue contrast and provides information about temperature, thus allowing to monitor ablation.

  4. Sonophoresis - Wikipedia

    en.wikipedia.org/wiki/Sonophoresis

    Low-frequency ultrasound is seen as the optimal level of ultrasound frequency. This is typically characterized as 20 to 100 kHz (sometimes 18 to 100 kHz). [7] Low frequency makes cavitation more likely. For reference, high frequency ultrasound is typically in the range of 1 to 3 MHz. [8]

  5. Medical imaging - Wikipedia

    en.wikipedia.org/wiki/Medical_imaging

    Medical ultrasound uses high frequency broadband sound waves in the megahertz range that are reflected by tissue to varying degrees to produce (up to 3D) images. This is commonly associated with imaging the fetus in pregnant women.

  6. Schlieren imaging - Wikipedia

    en.wikipedia.org/wiki/Schlieren_imaging

    The importance of the schlieren imaging technique is prominent in High Intensity Focused Ultrasound (HIFU) research and development. [5] Advantages of schlieren imaging include: Free field: the investigated acoustic field is not distorted by the measuring probe. High intensity measurements: the method is compatible with high acoustic intensities.

    en.wikipedia.org/wiki/Facial_recognition_system

    Facial recognition software at a US airport Automatic ticket gate with face recognition system in Osaka Metro Morinomiya Station. A facial recognition system [1] is a technology potentially capable of matching a human face from a digital image or a video frame against a database of faces.

  8. Therapeutic ultrasound - Wikipedia

    en.wikipedia.org/wiki/Therapeutic_ultrasound

    The ultrasound within tissue consists of very high frequency sound waves, between 800,000 Hz and 20,000,000 Hz, which cannot be heard by humans. Some of the advantages of ultrasound as a diagnostic and therapeutic tool include its safety profile, lack of radiation, portability, and low cost. [ 4 ]

  9. Ultrasound - Wikipedia

    en.wikipedia.org/wiki/Ultrasound

    An ultrasonic examination. Ultrasound is sound with frequencies greater than 20 kilohertz. [1] This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound.
