Abstract:
(EN) According to a method and a device for correcting defocused photoacoustic image distortion using an optical coherence tomography image provided in the present invention, a photoacoustic image distortion, which is generated due to the distance between the location of an ultrasonic transducer of a photoacoustic microscope imaging device and the acquisition location of a photoacoustic signal changed by means of sample scanning, can be corrected on the basis of an optical coherence tomography image. Therefore, photoacoustic image distortion in the depth direction generated in an existing photoacoustic microscope imaging device can effectively be corrected, and a more accurate photoacoustic tomography image can be obtained.
(FR) L'invention concerne un procédé et un dispositif de correction de distorsion d'image photoacoustique défocalisée, à l'aide d'une image de tomographie par cohérence optique, une distorsion d'image photoacoustique, qui est généré en raison de la distance entre l'emplacement d'un transducteur ultrasonore d'un dispositif d'imagerie de microscope photoacoustique et l'emplacement d'acquisition d'un signal photoacoustique modifié au moyen d'un balayage d'échantillon, peut être corrigé sur la base d'une image de tomographie par cohérence optique. Par conséquent, une distorsion d'image photoacoustique dans la direction de profondeur générée dans un dispositif d'imagerie de microscope photoacoustique existant peut être efficacement corrigée, et une image de tomographie photoacoustique plus précise peut être obtenue.
(KO) 본 발명에서 제안하고 있는 광단층 영상을 이용한 비초점 광음향 영상 왜곡 보정 방법 및 장치에 따르면, 광음향 현미경 영상기기의 초음파 트랜스듀서 위치와 샘플 스캐닝에 의해 변화하는 광음향 신호의 획득 위치 간의 거리로 인해 발생하는 광음향의 이미지 왜곡을 광간섭 단층 영상을 기준으로 광음향 영상의 왜곡을 보정할 수 있도록 구성함으로써, 기존의 광음향 현미경 영상기기에서 발생하는 깊이 방향으로의 광음향 영상의 왜곡을 효과적으로 보정 할 수 있고, 보다 정확한 광음향 단층의 영상 획득이 가능하도록 할 수 있다.
