in radiology, radiation deflected by scattering processes at angles greater than 90 degrees to the original direction of the beam of radiation.
Secondary radiation deflected more than 90° from the primary beam. See: scattered radiation.
One of two parameters measured in flow cytometry, which is detected at a 90º angle to a laser light beam and corresponds to the fluorescence of individual cells or intracellular components stained with rhodamine- or isothiocyanate-labelled monoclonal antibodies.
Electromagnetic radiation—usually understood to be photons, but also ultrasonic waves, etc.—that reflects > 90º from the source, or back in the general direction of a source.
Deflection of diagnostic radiation at angles exceeding 90 degrees to the direction of the beam.
in radiology, radiation deflected by scattering processes at angles greater than 90 degrees to the original direction of the beam of radiation. Important in radiotherapy when estimating surface exposure dose.
