  • Method and apparatus for producing a radiological image of an object
    Patent number: 4147935
    Abstract: A method and apparatus for producing an image of the X-ray attenuation characteristics of an object by positioning the object between a source of X-rays and a normally stationary X-ray sensing detector unit. The unit has a group of individually responsive detectors that sense a subfield consisting of a plurality of small contiguous detail areas of the object for a position of the X-ray source and the X-ray source is moved step-wise to sequential other positions to cause contiguous subfields to be sequentially sensed, each of which includes the plurality of detail areas.
