Digital Image Processing in Radioisotope Scanning

· IEEE Transactions on Bio-Medical Engineering
The ready availability and high speeds of small digital processors (minicomputers) has made possible fast translation to and from discrete time and frequency domains through the fast Fourier transform (FFT). Formerly time- consuming operations on sequences can now be performed more efficiently and easily in the discrete frequency domain. The FFT lends itself naturally to image processing and enhancement and in this communication is applied to line by line image processing of radioisotope scan data. The method has the potential of a vastly improved and more versatile display over existing line by line continuous methods, providing for detector point-spread distortion correction, variable spatial smoothing, line and area counts, data interpolation, and synthetic color coding for enhanced tube (CRT) display.
