ANALYTE INFORMATION ACQUISITION DEVICE AND CONTROL METHOD OF ANALYTE INFORMATION ACQUISITION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an analyte information acquisition device using a photoacoustic effect, capable of preventing dropout of a blood vessel and accurately recognizing the blood vessel.SOLUTION: An analyte information acquisition device comprises: light radiation means 102 for irradiating an analyte 110 with pulse light; an acoustic wave probe 105 for acquiring an acoustic wave generated in the analyte caused by the pulse light, and converting the acoustic wave into a photoacoustic wave signal; image creation means 109 for creating a three-dimensional image indicating characteristics of inside of the analyte on the basis of the photoacoustic wave signal; and image processing means 109 for acquiring a first tomographic image indicating a first tomographic surface in the three-dimensional image, and a projection image which is obtained by projecting the three-dimensional image to a two-dimensional plane, and creating a second tomographic image on the basis of the first tomographic image and the projection image.SELECTED DRAWING: Figure 1
