  • Explain briefly how a digital image is compressed in JPEG format.
  • Explain briefly Huffman coding process.
  • Assuming that the point spread function of a medical imaging system is expressed by the Gaussian function. Derive the equation to calculate the spatial resolution of the system.
  • How do you calculate the signal-to-noise ratio (SNR) of an image?
  • Discuss the spatial resolution of an imaging system both from its point spread function (PSF) and from its modulation transfer function (MTF).
