Photoacoustic Imager

摘要

In this photoacoustic imager, a light source driving portion is configured to stop power supply to a plurality of light-emitting semiconductor elements on the basis of that a forward voltage detection portion has detected forward voltage values of the plurality of light-emitting semiconductor elements corresponding to short circuiting of the light-emitting semiconductor elements.

主权项

1. A photoacoustic imager comprising:
a detection/generation portion capable of detecting an acoustic wave generated due to absorption of light by a detection object in a specimen and generating an ultrasonic wave to be applied to the specimen; a plurality of light-emitting semiconductor elements provided in the vicinity of the detection/generation portion and capable of applying light to the specimen; a light source driving portion supplying power for making the light-emitting semiconductor elements generate light to the light-emitting semiconductor elements; and a forward voltage detection portion capable of detecting forward voltage values of the light-emitting semiconductor elements, wherein the light source driving portion is configured to stop power supply to the light-emitting semiconductor elements on the basis of that the forward voltage detection portion has detected forward voltage values of the plurality of light-emitting semiconductor elements corresponding to short circuiting of the light-emitting semiconductor elements.
