Image processor for intra-surgical optical coherence tomographic imaging of laser cataract procedures

摘要

A cataract surgical system includes a laser source to generate a first set of laser pulses; a guiding optic to guide the first set of laser pulses to a cataract target region in an eye; a laser controller to generate an electronic representation of a target scan pattern, and to control the guiding optic to scan the first set of laser pulses according to a portion of the target scan pattern to create a first photo-disrupted region in the cataract target region; and a Swept-Source Optical Coherence Tomographic (SS-OCT) imaging system to generate an image of a portion of the first photo-disrupted region. The laser controller can generate an electronic representation of a modified scan pattern in relation to the image generated by the SS-OCT imaging system, and control the guiding optic to scan a second set of laser pulses according the modified scan pattern.

主权项

1. A cataract surgical system, comprising:
a laser source, configured to generate a first set of laser pulses; a guiding optic, coupled to the laser source, configured to guide the first set of laser pulses to a cataract target region in an eye; a laser controller, configured
to generate an electronic representation of a target scan pattern, andto control the guiding optic to scan the first set of laser pulses according to a portion of the target scan pattern to create a first photo-disrupted region in the cataract target region; a Swept-Source Optical Coherence Tomographic (SS-OCT) imaging system, configured to generate an image that includes a portion of the first photo-disrupted region with an image resolution in the range of 0.5-10 million image points per image and a frame-rate in the range of 20-500 frames/sec; and an OCT image processor, configured to perform an image analysis of the image, wherein the laser controller is configured
to generate an electronic representation of a modified scan pattern in relation to the image analysis performed by the OCT image processor, andto control the guiding optic to scan a second set of laser pulses according the modified scan pattern to create a second photo-disrupted region.
