  • Patent number: 6370265
    Abstract: A method for generating on demand a gray scale transfer curve for use in displaying an image comprised of a plurality of digital values representing pixel gray scale levels with a desired contrast and brightness. This is achieved by using a single sigmoid shaped function Y=f(X, a, b, c) resembling an H&D curve of a photographic film. The Y axis represents digital output values to be used in displaying an image, while the X axis represents input digital values representing captured image information. “a” is a number representing boundary conditions for X and Y, “b” is a first parameter controlling the location of the curve along the X axis and “c” is a second parameter controlling the slope of the curve slope. This function is used to derive a Look-Up-Table (LUT) representing a continuous GST curve having the desired contrast and brightness.

  • Patent number: 5155365
    Abstract: Radionuclide emission imaging is improved by correcting emission transmission data for attenuation along calculated path lengths and through calculated basis material. Single or dual energy projector data can be simultaneously obtained with radionuclide emission data to improve localization of radionuclide uptake. Dual energy x-ray projection techniques are used to calculate the path lengths and basis material (bone, tissue, fat). The radionuclide emission data and the transmitted x-ray data are simultaneously obtained using an energy selective photon detector whereby problems of misregistration are overcome. The dual-energy x-ray projection data are utilized to determine material-specific properties and are recombined into an effectively monoenergetic image, eliminating inaccuracies in material property estimation due to beam hardening. Use of a single instrument for simultaneous data collection also reduces technician time and floor space in a hospital.
