Shigeru Sase: Xenon CT apparatus, method of determining arterial blood rate constant, and method for calculating blood flow. Anzai Medical Kabushiki Kaisha, Squire Sanders & Dempsey, November 8, 2011: US08054936

In a blood flow measuring apparatus, a data processor in a computer determines three parameters from a (ΔCT value of CT image data corresponding to) time-course change, consisting of a test region rate constant K, an arterial blood rate constant Ka, and a xenon partition coefficient λ. A blood flow ...
