摘要

The present invention relates to distributed computing system to acquire, process, and display OCT images at real-time frame rates.

主权项

1. A method for computing optical image data comprising the steps of:
providing at least one graphics processing unit in communication, through a communication link, with at least one central processing unit for processing optical and ultrasound image data from a combined ultrasound (US)/optical coherence tomography (OCT) system, wherein the optical image data is generated by a swept-source OCT instrument; using the at least one graphics processing unit to perform a Fourier Transformation processing step on the optical image data; using the at least one central processing unit to perform a data acquisition step, a pre-processing step, and any other processing steps on the optical image data, wherein data acquisition step comprises synchronizing the swept-source optical coherence tomography instrument by clocking a light source, wherein one of the at least one central processing units performs at least one task on the optical image data and at least one task on the ultrasound image data; and transmitting the processed optical image data and ultrasound image data to a display device to thereby display images at real-time frame rates.
