| titleOfInvention | Bimodal imaging system and method based on array type optical fiber ultrasonic probe |
| abstract | The invention discloses a bimodal imaging system and a bimodal imaging method based on an array type optical fiber ultrasonic probe, and belongs to the field of medical imaging. The method comprises the following steps: the photoacoustic-ultrasonic excitation module is used for generating a plurality of paths of ultrasonic excitation laser and photoacoustic excitation laser; the mode switching module is used for selectively entering an ultrasonic imaging mode or a photoacoustic imaging mode; the array type optical fiber ultrasonic probe is used for transmitting excitation laser, generating corresponding ultrasonic waves in an ultrasonic imaging mode or a photoacoustic imaging mode, transmitting the ultrasonic waves to a sensing structure of the probe, reflecting and interfering the detection laser, and changing the interference intensity of the detection laser according to the intensity of an ultrasonic signal on the sensing structure; the optical fiber ultrasonic demodulation module is used for generating multi-path detection laser and demodulating a reflected optical signal with variable interference intensity into an electric signal; and the data processing module is used for reconstructing the bimodal image of the electric signal. The invention has the advantages of high imaging speed, large penetration depth, high imaging quality and the like. |
