Abstract: An ultrasound system (1) includes an ultrasound probe (2), a mobile information terminal (3), and an external apparatus (4). The ultrasound probe (2) includes a transmission and reception circuit (22) that transmits an ultrasonic wave from a transducer array (21) and generates a sound ray signal, and a reception data generation unit that generates reception data before imaging based on the sound ray signal. The mobile information terminal (3) includes a camera unit (33) that acquires a view image. The external apparatus (4) includes a display controller (44) that displays an ultrasound image generated based on the reception data and the view image on an external monitor (45), and an input device (47). In a case where a probe freeze instruction is input from the input device (47), the transmission of the ultrasonic wave from the transducer array (21) is stopped.

Abstract: There is provided a photoacoustic measurement apparatus capable of appropriately detecting a single failure state even in the single failure state so that it is possible to prevent an operation in the single failure state from continuing. There are included: a laser light source having a flash lamp and a laser medium; an excitation light source power supply having a capacitor for supplying a charge voltage to the flash lamp, a charging circuit for charging the capacitor, a first voltage dividing circuit and a second voltage dividing circuit for dividing a voltage charged in the capacitor, and a failure detection circuit that detects a failure by comparing voltages obtained by voltage division of the first voltage dividing circuit and the second voltage dividing circuit; and an ultrasound probe that detects photoacoustic waves generated inside a subject by emission of light emitted from the laser light source to the subject.
