PHOTOACOUSTIC IMAGING APPARATUS, PHOTOACOUSTIC SENSING STRUCTURE, AND METHOD OF CAPTURING PHOTOACOUSTIC IMAGE

摘要

A photoacoustic imaging apparatus for detecting a photoacoustic image of an object, a photoacoustic sensing structure, and a photoacoustic image capturing method are provided. The photoacoustic imaging apparatus includes an electromagnetic wave source for emitting an electromagnetic wave, a first electromagnetic wave transmissible substrate disposed on a transmission path of the electromagnetic wave, electromagnetic wave transmitting needles disposed on the first electromagnetic wave transmissible substrate, and an ultrasonic sensor disposed at one side of the object. The electromagnetic wave transmitting needles can be inserted into the object. The electromagnetic wave is transmitted to at least a part of the electromagnetic wave transmitting needles through the first electromagnetic wave transmissible substrate and to the inside of the object through at least the part of the electromagnetic wave transmitting needles. The inside of the object generates an ultrasonic wave in response to the electromagnetic wave. The ultrasonic sensor detects the ultrasonic wave.
