Abstract: Even when an insertion object is inserted to a deep position of a subject or even when the insertion object is inserted into the subject at an angle close to a right angle, it is possible to confirm the position of the insertion object in a photoacoustic image. The insertion object is, for example, a hollow puncture needle 15 that includes an opening at a tip thereof. The puncture needle 15 includes a light guide member 152 that guides light emitted from a first light source to the vicinity of the opening, and a light emitting portion 153 that is provided in the vicinity of the opening and emits the light. First photoacoustic waves, which are caused. by the light emitted from the light emitting portion 153, are generated in the puncture needle 15. A first photoacoustic image is generated on the basis of the first photoacoustic waves.

Abstract: In a laser apparatus, transmission of vibration, which is generated in a portion that generates a cooling gas flow, to a laser unit is suppressed, and heat generated from the laser unit is efficiently dissipated. A laser unit is housed inside a box-shaped housing having a plurality of faces. A frame supports a laser unit with a first mount interposed therebetween inside the housing. The frame has a through-hole penetrating from one face side to the other face side. A blower fan generates a flow of cooling gas for cooling the laser unit. The blower fan is attached to, for example, a second housing so as to face the laser unit. The cooling gas moves through the through-hole of the frame between the blower fan and the laser unit.

Abstract: An acoustic wave detector detects photoacoustic waves generated by absorbing measurement light emitted toward a subject, and reflected acoustic waves with respect to acoustic waves transmitted toward the subject. A preamplifier amplifies a detection signal output by the acoustic wave detector. A bypass unit is intended to output the detection signal without passing through the preamplifier. Controller causes the preamplifier to enter an operating state and selects a first path along which the detection signal is amplified by the preamplifier and then is input to the reception circuit as a signal path in a case where the photoacoustic waves are detected. The controller stops an amplification operation in the preamplifier and selects a second path along which the detection signal is input to the reception circuit via a bypass uni as the signal path in a case where reflected acoustic waves are detected.

Abstract: A photoacoustic measurement device reducing artifacts caused by photoacoustic waves generated at a surface portion of a subject on which measurement light is incident, and a signal processing method thereof are obtained. A photoacoustic measurement device includes region discrimination unit that discriminates an artifact generation region and an artifact non-generation region in a photoacoustic image on the basis of a positional relationship between a light emitting portion and an acoustic wave detection portion, and filter unit that performs a first filtering process on a first photoacoustic wave detection signal corresponding to a photoacoustic image of the artifact non-generation region and performs a second filtering process on a second photoacoustic wave detection signal corresponding to a photoacoustic image of the artifact generation region. The second filtering process includes further reducing the photoacoustic wave detection signal in a frequency range lower than a predetermined frequency as compared with the first filtering process.
