Regulatory Science Tools Catalog

MXR
This regulatory science tool presents a method to measure the radially variant contrast on virtual reality head-mounted displays (VR HMDs) using circular concentric ring patterns, which can be implemented to characterize image quality, including Michelson contrast and effective resolution, on VR HMDs equipped with optical lenses.
AI ML
This regulatory science tool presents a method (web-based decision tree) that may help developers select appropriate metric and endpoint for Artificial Intelligence (AI) / Machine learning (ML) classification algorithms in medical imaging.
CM&S Program Image
This regulatory science tool presents a method for assessing credibility of patient-specific computational models implemented in medical device software. 
Biocompatibility and Toxicology
This regulatory science tool is a method that applies the ISO 10993-17 toxicological risk assessment approach to medical device extractables screening data to assess systemic toxicity, genotoxicity, carcinogenicity, or reproductive/developmental toxicity in the biocompatibility evaluation of a medical device.
Neurology
This RST contains a set of machine or deep learning algorithms which can be utilized in the development of relevant medical devices to assist in the prediction of traumatic brain injury (TBI) and stroke according to resting electroencephalography (EEG).
Cardiovascualar
The 3D human induced pluripotent stem cell-derived cardiomyocyte (hiPSC-CM) Cardiac Contractility Modulation (CCM) Tool, 3D hiPSC-CM CCM Tool, is a laboratory method that includes detailed characterization and protocols for evaluating contractile response in healthy 3D hiPSC-CM models. The core elements of this tool include the ability to perform in vitro CCM contractility assays, including contraction force and kinetics, in 3D hiPSC models for various known and unknown electrophysiology pulse waveform parameters and combinations.
Cardiovascualar
This RST outlines a strategy for estimating the presence of cyclic phase transformation to aid in the determination of appropriate load levels for Fatigue to Fracture testing of nitinol components. Specifically, it includes a flowchart (Figure 1 in Appendix) to estimate the low to high cycle fatigue transition using either computational or experimental methods. Based on the output of the analysis, the user can create a test plan for fatigue testing per ASTM F3211 which includes both expected low cycle fatigue fractures and runouts.
MXR
This tool allows for the creation of immersive 3D scenes using a web browser. WebXR allows for an instant deployment of any 3D scene and scripts and does not need to cater to a specific 3D engine or headset hardware
AI ML
Tools that quantify wait-time-saving benefits for cases with positive diagnoses due to the adoption of Computer-Aided Triage and Notification devices in a radiology workflow
Infection Control
A tool which may be used for measuring aerosol emission from water-based heater cooler devices with product codes DWC or DWJ.
Materials Program Image
This tool provides protocols for conducting preclinical tests recommended in the FDA Guidance for tissue containment systems used during power morcellation procedures.
Orthopaedics
