  • Patent number: 6381351
    Abstract: A method for displaying on a display medium an image corresponding to detected exposures of a plurality of pixels converted to a matrix having n rows and m columns of digital values. The method comprises creating a weighted, smoothed, subtracted matrix, adding the weighted, smoothed, subtracted matrix to the starting matrix to produce an enhanced matrix; and then using the digital values from the enhanced matrix to display an image. Preferably, a sampled submatrix of digital values having n/I rows and m/I columns is created from the starting matrix from which is compiled a weighted, smoothed, subtracted submatrix that is then extrapolated to create the weighted, smoothed, subtracted matrix. A program storage device for carrying out the method, a digital x-ray image data capture system, and a method of using the system of this invention are also claimed.

  • Patent number: 6327336
    Abstract: A method for optimizing the radiogram image of a subject is provided. The method provides for showing the location of automatic exposure control sensors on the radiograms, along with alignment and targeting projections to optimize the radiation exposure of the subject. By displaying the location of the automatic exposure control sensors on the radiograms along with the image of the subject, the observers can determine whether the radiogram image was taken with appropriate subject alignment. This method also serves as an educational aid in training radiography technicians.
