Abstract : A technique utilizing x-ray fluorescence has been used to measure remotely the volume, and, thereby, hydrostatic pressure of a cesium nitrate solution in vitro. The excitation radiation source was (99m)Tc and the x-ray spectra were measured with a sodium iodide spectrometry system. This technique may be applicable to long-term in vivo measurements of intracranial pressure for conditions such as hydrocephalus.
