Use of personal computer for radioisotopic examination of renal function

Two-channel radiometric equipment (RE) for examination of renal function - the isotopic nephrogram (ING) does not meet many requirements. The access to the ING parameters has one disadvantage of being burdened by possibility of subjective error. To replace the mechanical registering devices, an interface has been developed with a program appliance for connecting 'Apple' computer to a 4-channel RE 'Gamma' (Hungarian produce). This system offers a broad registration range - extent of the interval from 1 to 256 sec. and number of intervals up to 256. Considerable are the opportunities for processing the ING: addition, subtraction, multiplication, shifting, superposition, leveling, restitution, access to the coordinates of a point, determination of Tmax. and T1/2, integration within indicated limits. The system is menu-driven. Tracing of floppy discs allows to complete small volume archives. 1 fig., 3 refs
