  • Patent number: 6646665
    Abstract: A thermal recording system for recording an image on a thermo-sensitive recording medium using a laser beam under a preheated condition of the thermo-sensitive recording medium. In the thermal recording system, a preheating device preheats the thermo-sensitive recording medium which has leuco dyes, a developer and light-absorbing dyes all provided on a support, and which develops color in a continuous tone at a density corresponding to the energy of the applied heat, to a predetermined temperature less than a color-developing temperature. A heating-beam generating device allows a laser beam to scan the thermo-sensitive recording medium so as to heat the thermo-sensitive recording medium to a predetermined color-developing temperature. Thus, the heating-beam generating device can control the laser beam in a sufficient control range, thereby making it possible to record an image on the thermo-sensitive recording medium with high accuracy.

  • Patent number: 5532726
    Abstract: Images or other information is recorded by a thermal recording apparatus on a thermosensitive recording medium which has a support coated with a coloring agent, a color developer, and light-absorbing dyes, and produces color whose density depends on thermal energy that is applied to the thermosensitive recording medium. The thermal recording apparatus has a plurality of laser beam generators for generating respective laser beams, and an optical scanning system for scanning the thermosensitive recording medium with the laser beams at respective different positions thereon. One of the laser beam generators produces a laser beam to scan the thermosensitive recording medium earlier than the laser beams generated by the other laser beam generators, and the laser beam has a thermal energy which is high enough to enable the thermosensitive recording medium to produce the color. The laser beam generators apply the respective laser beams at different incident angles to the optical scanning system.

  • Patent number: 5049748
    Abstract: Digital image signals are detected from radiation images of an object constituted of bones and soft tissues. A subtraction process is carried out with a predetermined parameter on the digital image signals, and a difference signal representing an image of part of the object is obtained. Each of images of a phantom, which has part exhibiting an equivalent radiation absorption coefficient to bones and/or part exhibiting an equivalent radiation absorption coefficient to soft tissues, is read out together with each object image. A value of the parameter is found, with which the image of either part of the phantom becomes erased in a subtraction image of the phantom obtained from subtraction processing. The value of the parameter, which has thus been found, is determined as an optimum value of the parameter. Subtraction processing is then carried out by using the optimum value of the parameter.
