摘要: A laser beam is applied to a photoacoustic wave generation source multiple times in a reception period of ultrasound waves during photoacoustic imaging. As a result, a plurality of photoacoustic waves are generated from the photoacoustic wave generation source in the reception period and received by a reception unit of an ultrasound imaging apparatus. The positions of the plurality of photoacoustic waves on a time axis is adjusted, and the plurality of photoacoustic waves are averaged. A photoacoustic image is generated based on a signal obtained through the averaging.

摘要: A guide wire is provided with a core shaft, a coil portion, a sound source, and wiring. The coil portion is coupled to a distal end portion of the core shaft and is helically wound around a periphery of the core shaft to the rearward. The coil portion includes an open portion in which an interval of element wires constituting the coil portion itself is larger than that in another portion. The sound source is provided in an inner side of the open portion. The wiring extends along an extending direction of the core shaft, and a distal end of the wiring is positioned at an inner side of the coil portion. The wiring supplies energy to the sound source.

摘要: A beacon device is housed within a recess portion. The beacon device has a tip end to be housed in a tip end portion. A photoacoustic wave source is disposed at the tip end of the beacon device. The tip end portion contains an ultrasonic propagation medium such as water. With the beacon device housed within the recess portion, a light generating device is connected with a rear end of the beacon device to irradiate the photoacoustic wave source with laser light. A photoacoustic signal emitted from the photoacoustic wave source is received by an ultrasonic probe. Whether the beacon device and the light generating device are connected is determined based on the received signal.

摘要: Provided is an acoustic coupler for ultrasound imaging that can detect a posture of an ultrasound probe from an image. An acoustic coupler includes: a first layer in contact with an ultrasound probe of an ultrasound imaging device; a second layer in contact with an imaging target; and an intermediate layer made of a material having a high elastic modulus between the first layer and the second layer. The intermediate layer includes a plurality of markers made of a material that reflects an ultrasound wave, at different positions in an ultrasound wave propagation direction, for example, near a boundary between two adjacent layers. The ultrasound imaging device detects the posture of the ultrasound probe based on images of the markers included in an ultrasound image.
