摘要：
PURPOSE: A method and a device of generating an ultrasound image and a photoacoustic image are provided to obtain an image with improved spatial resolution, contrast, and a low noise level for the ultrasound image and the photoacoustic image by estimating an optimal ultrasound speed to be used for image restoration.CONSTITUTION: A method of generating an ultrasound image and a photoacoustic image includes a step of emitting a laser pulse to a target (200) a step of generating the photoacoustic image by receiving an ultrasound signal when the target absorbs the emitted laser pulse, and the ultrasound signal is generated (210) a step of estimating an optimal ultrasound speed from the generated photoacoustic image (220) a step of emitting an ultrasound pulse to the target (230) a step of performing beam convergence and orthogonal demodulation for the received ultrasound signal from the target by using the estimated optimal ultrasound speed (240) and a step of generating the ultrasound image by using an orthogonal demodulation performing result (250).COPYRIGHT KIPO 2013[Reference numerals] (200) Emit a laser pulse to a target (210) Generate a photoacoustic image by receiving an ultrasound signal when the target absorbs the emitted laser pulse, and the ultrasound signal is generated (220) Estimate an optimal ultrasound speed from the generated photoacoustic image (230) Emit an ultrasound pulse to the target (240) Perform beam convergence and orthogonal demodulation for the received ultrasound signal from the target by using the estimated optimal ultrasound speed (250) Generate an ultrasound image by using an orthogonal demodulation performing result (260) Generate a fusion image by using the photoacoustic image and the ultrasound image (AA) Start (BB) End본 발명은 초음파 영상 및 광음향 영상 생성 방법에 관한 것으로서, 레이저 펄스를 관심 대상에 발사하고, 발사된 레이저 펄스가 관심 대상에 흡수되어 초음파 신호가 발생되면, 초음파 신호를 수신하여 광음향 영상을 생성하고, 생성된 광음향 영상으로부터 최적의 초음파 속도를 추정하고, 초음파 펄스를 관심 대상에 조사하고, 추정된 최적의 초음파 속도를 이용하여 관심대상으로부터 수신된 초음파 신호에
