Function

TO PLOT OR MAP THE INTENSITY DISTRIBUTION OF A RADIOACTIVE ISOTOPE IN A LOCALIZED AREA OF THE BODY, IN ORDER TO ASSIST IN DIAGNOSIS OF DISEASE.

Technical

AT THE TIME OF ITS PURCHASE (1971), THIS SCANNER WAS THE MOST ADVANCED DEVICE OF ITS TYPE. IN OPERATION, RADIATION FROM THE SOURCE IMPINGES ON THE DETECTING CRYSTAL IN A SCINTILLATION PROBE (THE RADIATION FIRST PASSES THROUGH THE COLLIMATOR WHICH PERMITS THE CRYSTAL TO VIEW ONLY THE RADIATION DIRECTLY BELOW IT DURING THE SCAN). THE RADIATION ABSORBED BY THE CRYSTAL IS CONVERTED TO A LIGHT FLASH WHICH, THROUGH A SERIES OF STEPS, IS CONVERTED TO AN IMAGE ON EITHER ELECTROSENSITIVE PAPER (DOT RECORDING) OR X-RAY FILM (PHOTO RECORDING) ON 14 X 17 INCH FILM. THE RESULTING MAP CONSISTS OF MULTIPLE BLACK DOTS ON A WHITE OR CLEAR GROUND, THE FREQUENCY OF DOT OCCURRENCE INDICATING THE DEGREE OF CONCENTRATION OF RADIOACTIVE MATERIAL & HENCE THE LEVEL OF ACTIVITY OF THE ORGAN. THIS EXAMPLE HAS THE COLOUR DOT RECORDING OPTION AS WELL. (MANUALS T55-627 & T55- 564.)
