ULTRASOUND IMAGE CONSTRUCTION METHOD, ULTRASOUND IMAGE CONSTRUCTION APPARATUS, ULTRASOUND IMAGE CONSTRUCTION PROGRAM, AND METHOD FOR EVALUATING SKIN

摘要

The present invention provides an ultrasound image construction apparatus that is capable of constructing, relatively easily and with high accuracy, an ultrasound tomographic image of a very thin subject to be measured having a layer structure in a manner such that the layer structure can be understood intuitively. An ultrasound probe (13) of this ultrasound image construction apparatus (1) transmits an ultrasonic wave to a subject to be measured (8) and a reference substance (10) which are disposed in contact with a substrate (9) so that the ultrasound wave enters the subject to be measured (8) and the reference substance (10) via the substrate (9) and an impulse response for an ultrasonic waveform is received. A calculation means (31) performs a calculation of estimating acoustic property distribution in a depth direction factoring in the influence of multiple reflections on the basis of standardized impulse response information obtained from the impulse response information of the ultrasonic waveform that entered the reference substance (10) and the impulse response information of the ultrasonic waveform that entered the subject to be measured (8). An image construction means (31) constructs image data of an acoustic property image on the basis of the acoustic property distribution in the depth direction obtained by the calculation means (31).
