  2. CT scan - Wikipedia

    en.wikipedia.org/wiki/CT_scan

    Positron emission tomography–computed tomography is a hybrid CT modality which combines, in a single gantry, a positron emission tomography (PET) scanner and an X-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image.

  3. Medical imaging - Wikipedia

    en.wikipedia.org/wiki/Medical_imaging

    Tomography is the imaging by sections or sectioning. The main such methods in medical imaging are: X-ray computed tomography (CT), or Computed Axial Tomography (CAT) scan, is a helical tomography technique (latest generation), which traditionally produces a 2D image of the structures in a thin section of the body. In CT, a beam of X-rays spins ...

  5. Multispectral optoacoustic tomography - Wikipedia

    en.wikipedia.org/wiki/Multispectral_optoacoustic...

    Tomography. This term denotes images formed by combining raw measurements from multiple points around the specimen in a mathematical inversion scheme. This process is analogous to x-ray computed tomography, except that tomographic mathematical models describe light and sound propagation in tissues. Fig. 1: Operational capabilities of MSOT.

  6. Cone beam computed tomography - Wikipedia

    en.wikipedia.org/wiki/Cone_beam_computed_tomography

    Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, flat panel CT or Digital Volume Tomography (DVT)) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone.

  7. PET-CT - Wikipedia

    en.wikipedia.org/wiki/PET-CT

    Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image.

  8. Contrast CT - Wikipedia

    en.wikipedia.org/wiki/Contrast_CT

    Contrast CT, or contrast-enhanced computed tomography (CECT), is X-ray computed tomography (CT) using radiocontrast. Radiocontrasts for X-ray CT are generally iodine-based types . [ 1 ] This is useful to highlight structures such as blood vessels that otherwise would be difficult to delineate from their surroundings.
