Systems for extended depth frequency domain optical coherence tomography are provided including a detection system configured to sample spectral elements at substantially equal frequency intervals, wherein a spectral width associated with the sampled spectral elements is not greater than one-half of the frequency interval. Related methods are also provided herein.
Optical coherence tomography (OCT) imaging systems for imaging an eye are provided including a source having an associated source arm path and a reference arm having an associated reference arm path coupled to the source path, the reference arm path having an associated reference arm path length. A sample having an associated sample arm path coupled to the source arm and reference arm paths is provided. A reference arm path length adjustment module is coupled to the reference arm. The reference arm path length adjustment module is configured to automatically adjust the reference arm path length such that the reference ...
Methods, systems and computer program products for managing frequency domain optical coherence tomography (FDOCT) image resolution. A spectrum used to acquire an image of a subject is calibrated and default dispersion correction parameters are set. Default dispersion management parameters associated with a region of the image of the subject are also set. The image of the subject is acquires after setting the default dispersion correction parameters and the default dispersion management parameters. A quality of the acquired image is compared to a quality metric for the acquired image. The dispersion correction parameters are adjusted if the quality of the acquired ...
Retina Today Journal Club moderators Jonathan Prenner, MD, and Richard Kaiser, MD, invited Justis Ehlers, MD, Assistant Professor at the Cleveland Clinic to discuss his work with intraoperative optical coherence tomography (OCT) guidance and how it relates to a retina surgeon. OCT has been used in clinical practice for over 10 years. This addition to practice has revolutionized the way the retinal anatomy is viewed and it's also provided a new perspective on how treatment affects anatomic changes in the retina. The next step is to bring OCT into the surgical suite in a way that provides high-resolution imaging ...

Macular disease in children is routinely recorded in drawings and color photographs, and less commonly through angiography performed under anesthesia. Technhiques used to evaluate function include preferential looking, figure or letter recognition, visual evoked potentials, and electroretiograms.
Bioptigen. Ophthalmology and General Research Systems. Bioptigen has pioneered a new class of in vivo optical imaging systems for biomedical applications. These systems enable real-time non-invasive imaging of internal tissue microstructure, advancing critical applications in drug development, genetics research, tissue engineering, and medical vision. Bioptigen is a spin-out of the Duke University Biomedical Engineering Department. Bioptigen was incorporated in North Carolina in August, 2004, to commercialize technologies originating in the laboratories of Professor Joseph Izatt. Bioptigen technology is based on the science of Optical Coherence Tomography (OCT), an imaging system similar in function to ultrasound, but using low-power light rather than sound waves. OCT offers resolution 100-times finer than standard ultrasound, suitable for analyzing tissue microstructure with features smaller than 10 micrometer.
Bioptigen allows you to sum up multiple images of a particular cut.In New Technology: Bioptigen SDOCT Boosts Flexibility
Bioptigen is very pleased to extend its relationship with Case through this new technology agreement. The intellectual property licensed by Case is fundamental to our ability to provide the highest performance FDOCT imaging system today and to develop new clinical tools that will dramatically extend the clinical value of FDOCT into the future.Eric L. Buckland in Case Western Reserve University, University Hospitals Case Medical Center and Bioptigen Establish Exclusive Licensing Agreement
We look forward to working with Bioptigen to incorporate the Case technology and expand their product portfolio to address medical disciplines beyond ocular imaging.In Case Western Reserve University, University Hospitals Case Medical Center and Bioptigen Establish Exclusive Licensing Agreement
