2. Signal-to-noise ratio (imaging) - Wikipedia

   en.wikipedia.org/.../Signal-to-noise_ratio_(imaging)

   The sensitivity of a (digital or film) imaging system is typically described in the terms of the signal level that yields a threshold level of SNR. Industry standards define sensitivity in terms of the ISO film speed equivalent, using SNR thresholds (at average scene luminance) of 40:1 for "excellent" image quality and 10:1 for "acceptable ...

   Most PACS handle images from various medical imaging instruments, including ultrasound (US), magnetic resonance (MR), Nuclear Medicine imaging, positron emission tomography (PET), computed tomography (CT), endoscopy (ES), mammograms (MG), digital radiography (DR), phosphor plate radiography, Visible Light Photography (VL), Histopathology, ophthalmology, etc. Additional types of image formats ...

5. Flat-field correction - Wikipedia

   en.wikipedia.org/wiki/Flat-field_correction

   In X-ray imaging, the acquired projection images generally suffer from fixed-pattern noise, which is one of the limiting factors of image quality. It may stem from beam inhomogeneity, gain variations of the detector response due to inhomogeneities in the photon conversion yield, losses in charge transport, charge trapping, or variations in the ...

   It combines 3D imaging with Doppler analysis to create the additional dimension – velocity. [15] A 60GHz 4D imaging radar sensor from Vayyar Imaging. A 4D imaging radar system measures the time of flight from each transmitting (Tx) antenna to a target and back to each receiving (Rx) antenna, processing data from the numerous ellipsoids formed.
