About this file
This document is a Statement of Work (SOW) for the development of a miniaturized Optical Coherence Tomography (OCT) device, referred to as the "mini OCT prototype," to be used for imaging the macula and optic nerve head during spaceflight. The key requirements include the ability to register the mini OCT images with the existing OCT2 Spectralis device on the International Space Station, as well as considerations for the form factor, connectivity, software workflow, radiation mitigation, magnetic components, dust mitigation, power consumption, temperature limits, maintenance, user guidance, acceleration, and off-gassing.
The SOW is part of a federal contract opportunity with NASA's Shared Services Center, solicitation number 80NSSC25886106Q, for the development and delivery of the mini OCT unit. The total contract value is $245,000, with a period of performance from October 1, 2024, to October 31, 2025. The first milestone is a white paper document that provides design considerations per NASA's requirements, valued at $120,000. The second milestone is the delivery of the mini OCT unit with the new form factor and all required functionality, valued at $125,000.

Introduction:
Today’s commercial off the shelf Optical Coherence Tomography (OCT) is a non-invasive diagnostic technique that renders an in vivo cross-sectional view of the retina. Due to the transparency of the eye (i.e., the retina can be viewed through the pupil), OCT utilizes a concept known as inferometry to create a cross-sectional map of the retina that is accurate to within at least 10-15 microns.
Spaceflight Associated Neuro-ocular Syndrome (SANS) is an important spaceflight risk that NASA is studying to better understand if mitigation strategies are necessary during long duration spaceflight. OCT is the primary imaging modality used by experts to measure changes in the retina during spaceflight. The OCT device currently on ISS is a Heidelberg Engineering Spectralis2 device. However, for lunar and mars missions, the device needs to be significantly smaller and lighter. We will refer to the desired prototype as mini OCT prototype since it is a miniaturized OCT device.
Objective/Requirement Mini OCT unit that can image:
o Macula o Optic Nerve Head o Ability for mini OCT images to register with OCT2 Spectralis to enable follow up analysis
(including retinal nerve fiber layer thickness measures from macula fixation images, and total retinal thickness measure from optic nerve head fixation).
Characteristics, Scope, and Spec Following considerations should be made when designing the device:
• Form factor of the device
• Connectivity to computer on station
• Changes to Software workflow for transferring data from device and colocalize data
• Radiation mitigation
• Magnetic components design considerations
• Dust mitigation
• Power consumption
• Temperature limits and cooling
• Maintenance and repair
• User guidance during measurements
• Acceleration and vibration
• Off gassing concerns
Milestone 1: Cost
- White-paper document that provides design considerations per NASA’s requirement.
120K
Milestone 2:
- Delivery of the unit with the new form factor and all functionality per the requirements agreed to by both parties.
o Note: the device will have no FDA clearance
125K
- Total 245K
Period of Performance: October 1st 2024 – October 31st 2025
