Document Type and Number:

Japanese Patent JPH0642884

Kind Code:

B2

Abstract:

A local cerebral blood flow measuring apparatus includes an expiratory tube arranged along a slice within a photography area of a gantry, and a sensor for detecting end of expiration. The expiratory tube includes a chamber for storing only an end tidal air, in synchronism with the end of expiration detected by the sensor. The end tidal air storage chamber and a subject to be examined are scanned with X-rays from the gantry, in synchronism with the end tidal air. The tracer concentration of the end tidal air storage chamber is measured by means of data derived from the gantry.
