PHOTOACOUSTIC IMAGE GENERATING DEVICE AND INSERTION OBJECT

摘要

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.

主权项

1. A photoacoustic image generating device comprising:
a first light source; an insertion object of which at least a part is inserted into a subject and which has a light guide member guiding light emitted from the first light source, a light emitting portion emitting the light guided by the light guide member, and a photoacoustic wave generating portion generating first photoacoustic waves caused by the light emitted from the light emitting portion; an acoustic wave detecting part for detecting the first photoacoustic waves that are generated from the insertion object after at least a part of the insertion object is inserted into the subject; and a photoacoustic image generating part for generating a first photoacoustic image on the basis of the first photoacoustic waves.
