AB  - The first recorded means of measuring physiological dynamics was in the 18th century using madder-root as a bone tracer. Today, to measure and visualize the functioning of in-vivo components is only a matter of tracer choice. The cerebral dynamics is measured with the metastable daughter of Molybdenum-99, Technetium Sodium Pertechnetate. In the decay of 99m-Tc a 140 Kev interval conversion photon is considered in the dosimetry. The means of converting photon events to a visual image is through the Dynacamera. The image detector consists of a collomator, 19 photomultiplier tubes, and a 132-1/2-diameter, 1/2--thick Na(TI) scintillation crystal. Each photomultiplier tube produces a signal descriptive of position and energy photon events by a matrix array. Pulse-height analysis is performed on the signal before it is presented for output display. The final output data may be an isotope photopeak, count rate or information density profile.
