Outline of Final Research Achievements |
Medical tomography can provide quantitative estimates of physiological or metabolic parameters. This usually requires obtaining multiple arterial blood samples during dynamic scans. As this procedure is considered a health risk for the patient and medical personnel, a measurement of arterial tracer concentration using medical tomography has been devised that can be used to obtain an input function with minimum discomfort to the patient and without drawing arterial blood. However, measured input functions in medical tomography are influenced by disturbing factors. We have developed a phantom of an arterial input-function. Correction-coefficients of the input function were obtained by means of this phantom. Thus, a measurement of arterial tracer concentration as an input function has been improved by correction-coefficients using our phantom.
