Abstract
An image generation device that generates an image of a subject includes a processor configured to generate an ultrasonic image based on a reflected ultrasound signal, generate a photoacoustic image based on a photoacoustic wave signal, and generate an estimated photoacoustic image based on the photoacoustic image and the ultrasonic image.
Claims20
An image generation device comprising:
- one or more processors comprising hardware, the one or more processors being configured to:
- receive a first ultrasonic image generated based on a first reflected ultrasound signal obtained by observing a subject at a first ultrasound time;
- generate a first photoacoustic image based on a first photoacoustic wave signal obtained by observing the subject at a first photoacoustic time;
- generate a second photoacoustic image based on a second photoacoustic wave signal obtained by observing the subject at a second photoacoustic time after the first ultrasound time and after a first period elapsed from the first photoacoustic time;
- and
- generate, before generating the second photoacoustic image, an estimated photoacoustic image that estimates the subject at the second photoacoustic time based on the first photoacoustic image and the first ultrasonic image.
