The work was published in Biomedical Optics Express . "About one million people suffer heart attacks every year, and there is currently no cure for the resulting cardiac tissue scarring ...

Optical coherence tomography has become a standard technique in ophthalmology, thanks to its easy fit with clinical workflows and the ability to image particular zones of the eye, such as the anterior chamber and the cornea. Use of the same technique to image the whole eye has proved challenging. OCT's limited imaging depth can be improved though Fourier domain methods and use of modern swept-source laser sources, but the optics of the eye prevent the focusing of light on both the anterior chamber and the retina simultaneously without sacrificing resolution. A project from Poland's Nicolaus Copernicus University and ...
