It is necessary that radiographing during operation is carried out speedily with high accuracy. Also, it is important that the image produced can provide a doctor with highly valuable diagnostic information. Until now, we have radiographed patients by inserting a conventional cassette together with a staitionary grid into a narrow space in the operation table, or directly into the back of the patient. For this reason, it has often been necessary to re-radiograph the patient due to accidental slippage of the staitionary grid. Also, since it has been difficult to put the cassette in the proper position, there was great difficalty in handling them. At the same, there have been various problems in the radiographic images. We have devised and manufactured a stationary grid-combined cassette which is suitably adaptable to operation tables, measured and compared the sharpness and graininess of radiographic images obtained by use of a conventional cassette and a stationary grid-combined cassette, respectively, together with the use of Konica Intensifying Screens and Konica New A film.
