ABSTRACT:
A measuring technique for eliminating the ballistic artifacts created by the mechanical body recoil upon the motion of the heart and the surge of blood within each heart cycle. The limb is restrained by mechanical devices which channel the kinetic energy into a motion which is in a plane favorable to the measurement. A magnetic field is created in the area where blood flow is to be recorded. The ballistic artifact creates a perturbative component in the desired blood flow waveform recording. This perturbation is eliminated by placing an electrically conductive loop around the limb near the location of the blood flow measuring electrodes and amplifying the signal produced by the loop to produce a ballistic signal. This loop signal is then added, subtractively, to the combination of blood flow plus perturbation signal from the electrodes to substantially cancel out the undesired ballistic component.
