  2. Single-photon emission computed tomography - Wikipedia

    en.wikipedia.org/wiki/Single-photon_emission...

    SPECT image (bone tracer) of a mouse MIP Collimator used to collimate gamma rays (red arrows) in a gamma camera. Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1]

  3. Gated SPECT - Wikipedia

    en.wikipedia.org/wiki/Gated_SPECT

    Gated SPECT is a nuclear medicine imaging technique, typically for the heart in myocardial perfusion imagery. [1] An electrocardiogram (ECG) guides the image acquisition, and the resulting set of single-photon emission computed tomography (SPECT) images shows the heart as it contracts over the interval from one R wave to the next.

    The actors who welcome the spect-actor volunteering onto the stage play against the spect-actor's attempts to intervene and change the story, offering a strong resistance so that the difficulties in making any change are also acknowledged. Augusto Boal presenting a workshop on the Theatre of the Oppressed in New York City.

  5. List of musical symbols - Wikipedia

    en.wikipedia.org/wiki/List_of_musical_symbols

    Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...

  6. Spectrometer - Wikipedia

    en.wikipedia.org/wiki/Spectrometer

    An XPS spectrometer. A spectrometer (/ s p ɛ k ˈ t r ɒ m ɪ t ər /) is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed.

  7. DICOM - Wikipedia

    en.wikipedia.org/wiki/DICOM

    DICOM is used worldwide to store, exchange, and transmit medical images.DICOM has been central to the development of modern radiological imaging: DICOM incorporates standards for imaging modalities such as radiography, ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and radiation therapy.

  8. Partial volume (imaging) - Wikipedia

    en.wikipedia.org/wiki/Partial_volume_(imaging)

    The partial volume effect can be defined as the loss of apparent activity in small objects or regions because of the limited resolution of the imaging system. It occurs in medical imaging and more generally in biological imaging such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT).

  9. Spectral imaging - Wikipedia

    en.wikipedia.org/wiki/Spectral_imaging

    In other words, the camera has a high spectral resolution. The phrase "spectral imaging" is sometimes used as a shorthand way of referring to this technique, but it is preferable to use the term "hyperspectral imaging" in places when ambiguity may arise. Hyperspectral images are often represented as an image cube, which is type of data cube. [3]
