title: Microprocessor system for tracking isodensity lines in film dosimetry.
abstract: Using a microprocessor a method for plotting isodensity lines in film dosimetry is described. The procedure moves the measuring spot directly along an isodensity line, using information obtained in preceding steps to determine the next step. For registration of the curves no X-Y pen recorder is needed. The essentials of the procedure together with a flowchart are given.
