  • Patent number: 4873441
    Abstract: An apparatus for recording and reading out radiation image information including a circulatory feed system for feeding stimulable phosphor sheets. Prior to successive recording of images on the stimulable phosphor sheets, any remaining images and dust are erased from the sheets, and the sheets are checked for defects or scratches thereon. Any sheet bearing such a defect is controlled to skip image recording, readout, and erasing steps. The frequency of erasing the remaining image on a stimulable sheet in the erasing step is controlled dependent on the amount of the radiation to which the object is exposed.

  • Patent number: 4868749
    Abstract: A signal processing method in autoradiography for determination of the base sequence of DNA or a DNA fragment, employing groups of radioactively labeled base specific cleavage products or mixtures thereof obtained by specifically cleaving the DNA or DNA fragment labeled with a radioactive element and resolved one-dimensionally in parallel relation to each other to form resolved rows on a support medium. An autograph is obtained having locational information on groups of radioactively labeled cleavage products contained in the rows on the support medium. An electrical digital signal corresponding to the autoradiograph is then generated. Sampling points in each resolved row of the digital signal are next detected. Reference sampling points are then determined in a plurality of reference rows which are either directly provided on resolved row adjacent to the reference row to identify sampling points in adjacent resolved rows.

  • Patent number: 4861994
    Abstract: A method of measuring an after-glow of a stimulable phosphor sheet comprises the step of detecting an instantaneous light emission after-glow emanated by the stimulable phosphor sheet carrying a radiation image stored thereon by use of a photodetector when the stimulable phosphor sheet is being conveyed toward a system for final read-out after preliminary read-out is finished, thereby measuring the level of the after-glow. A method of adjusting radiation image read-out conditions comprises the steps of creating a histogram of preliminary read-out image signals obtained by preliminary read-out, detecting the instantaneous light emission after-glow by a photodetector, obtaining a signal Sx representing the level of the instantaneous light emission after-glow, and adjusting final read-out conditions and/or image processing conditions based on a value calculated by subtracting the value of the signal Sx from a characteristic value of the preliminary read-out image signals in the histogram.
