Ultrasound diagnostic apparatus

An ultrasound diagnostic apparatus comprising:

• a controller that has a first processor configured to function as a synchronization signal generation unit generating a first synchronization signal for controlling transmission and reception of an ultrasonic wave in an ultrasound probe, and controls the ultrasound probe based on the first synchronization signal;
• a second processor configured to function as an ultrasound image generation unit that generates an ultrasound image based on a signal detected by the ultrasound probe;
• and
• a connector that has a synchronization signal line transmitting a second synchronization signal generated in the synchronization signal generation unit and a data line transmitting data independently of the synchronization signal line, and outputs the second synchronization signal to the outside through the synchronization signal line,
• wherein the connector is configured such that a light source device, which includes a laser diode or light-emitting diode, emitting light incident on an insertion object having a photoacoustic wave generator absorbing the light and generating a photoacoustic wave and an electrocardiograph that stores identification information are connectable in common,
• wherein the controller is configured to output the second synchronization signal from the connector to the light source via the synchronization signal line if no identification information is obtained, and outputs the second synchronization signal corresponding to the electrocardiograph from the connector to the electrocardiograph via the synchronization signal line if the identification information indicating the electrocardiograph is obtained.
