<P>PROBLEM TO BE SOLVED: To enable a more quantitative measurement of the amount of oxygen in blood in the oxygen amount measurement in blood where an optoacoustics analysis method is used. <P>SOLUTION: In the oxygen amount measurement in blood where the optoacoustics analysis method is used, the number of molecules m of hemoglobin in blood in a blood vessel is calculated based on the cross-sectional image data V of the blood vessel, an oxygen saturation degree SpO<SB POS="POST">2</SB>of the blood in the blood vessel is calculated based on a signal strength Po (800) of a first photoacoustic wave and a signal strength Po (756) of a second photoacoustic wave, and an oxygen amount VO<SB POS="POST">2</SB>in the blood is calculated based on the number of molecules m and the oxygen saturation degree SpO<SB POS="POST">2</SB>. <P>COPYRIGHT: (C)2013,JPO&INPIT |
