Application of ImageJ in Optical Coherence Tomography Angiography (OCT-A): A Literature Review

Figure 1

An ImageJ-processed superficial choriocapillary plexus (SCP) image of a patient presenting with a vascular disorder was utilized to enhance the visibility of the pathological vascular structure. (A) Optical coherence tomography angiography SCP image (OCT-A). (B) Implementation of a rolling ball background subtraction to enhance contrast and darkness of the background. (C) Implementation of a rolling ball background to increase the brightness of the background in preparation for thresholding the image. (D) Pathologic vessel structure, indicated by a green arrow, became visible in the thresholding image generated by the Otsu method alongside a rolling ball background subtraction.
