ORLANDO, Fla., Sep. 15, 2025 —ScanLabMR, the global leader in MRI and CT simulation and education software, today unveiled its newest innovation: the Signal-to-Noise Ratio (SNR) Calculator. This cutting-edge feature gives MRI technologists, radiologists, and educators a smarter, more reliable way to understand and optimize image quality.
Currently available SNR calculators provided by MRI manufacturers often fall short, offering only partial calculations and measurements that fail to capture all the complex variables affecting SNR. In particular, these tools cannot account for the composition of various tissues within the imaging slice in real time—a critical limitation that leads to an overall misunderstanding of SNR in clinical practice.
ScanLab’s breakthrough SNR Calculator overcomes these limitations by prospectively calculating the true SNR outcome based on the user’s prescribed slices. This allows for the creation of quantitative SNR values that account for all parameter adjustments and physical factors present within the MRI environment.

The competitive advantage lies in its predictive power: users can estimate SNR outcomes before performing a scan. This unique capability allows students and professionals to explore parameter changes, test protocol variations, and understand trade-offs between image quality and scan time—all in a safe, risk-free learning environment.
“Accurate SNR modeling is a crucial step toward advancing MRI education and clinical practice, because it has never been done accurately before,” said Matthew Hayes, President and Creator of ScanLabMR. “We believe every user should have access to this level of insight without worrying about whether they can afford it. That’s why we’re including the SNR Calculator in all existing licenses at no extra charge. Our mission is to give MRI professionals the tools they need to take ownership of image optimization and deliver the highest quality of care.”
By making the SNR Calculator freely available to all current users, ScanLab reinforces its commitment to ensuring that cutting-edge technology for education and training remains accessible to students, technologists, and radiologists worldwide.
This new tool also strengthens ScanLab’s position as the go-to resource for MRI education and simulation, offering institutions, hospitals, and training programs an unrivaled platform for teaching and skill development. By enabling learners to experiment with protocol adjustments virtually, ScanLab empowers MRI professionals to move beyond vendor presets and take control of image optimization.
Key Benefits of the ScanLab SNR Calculator:
● More accurate than manufacturer calculators
● Predictive insight into SNR outcomes without running a scan
● Educational value for students and technologists learning the impact of protocol changes
● Competitive edge for institutions training the next generation of MRI professionals
About ScanLab
ScanLab is the first-ever MRI and CT simulator that quantifies and assesses clinical competence and scan quality. ScanLab’s revolutionary virtual software replicates real-life MRI and CT scans and clinical situations so users can experience all thoughts and practices of being at the scanner but without unnecessary safety risk to the patient, loss of revenue, and time and scheduling constraints. ScanLabMR and ScanLabCT also provides educators and managers with the tools to evaluate and quantitatively assess user performance to bring a higher standard of education and training to universities, hospitals, and medical facilities.

This sounds like a good idea. But how can it be installed on an existing MRI scanner? Adding additional software would constitute a violation of the FDA-approved software configuration.
There does not appear to be any information on this product on the Scanlab website. If it's a stand-alone product, i.e. the scan parameters must be entered manually, it takes time that will impact its usefulness--by and large, imaging protocols are set up and not changed from patient to patient, so when it's necessary to change them on the fly with the patient in the magnet, techs want to move quickly.
For advance planning of protocols, a calculator that would provide estimated contrast-to-noise ratio would be very nice.
