Advancing Quantitative MRI! We’re excited to see you at ISMRM in Cape Town at Booth C15. Stop by to talk about data quality, standardization, reproducibility, and quantitative imaging in the age of AI.
Integrated hardware/software platform: clinical trials, QA/QC, R&D, and AI/ML validation/testing
Looking back to 2025, we want to thank the hundreds of customers and collaborators who authored more than 60 papers, talks, and abstracts using CaliberMRI phantoms. Products cited include: (1) Relaxometry phantoms (T1, T2, PD) – National Institute of Standards and Technology (NIST)/ISMRM Model 130 (as well as Models 136 and 106) (2) Diffusion phantom […]
Join us for open office hours! Ask questions about your phantom, qCal-MR and meet others advancing quantitative MRI!
CaliberMRI is excited to participate in Innosphere’s 2026 Life Sciences Incubator Startup.
Are you heading to ASTRO next week? If so, take a look at some incredible articles below (some hot off the press!). Please reach out directly to authors on their work or to CaliberMRI on our phantoms. If you’d like to set up a meeting at ASTRO, please reach out to us directly at info@qmri.com. […]
Multiparametric Tissue Mimics for Breast Imaging and Medical Device Testing

We present our work on developing anatomically realistic, quantitative multiparametric MRI (qMRI) phantoms designed to standardize imaging of both healthy and diseased breast tissue. The lack of standardized, morphology-accurate phantoms currently limits the effectiveness of qMRI in both clinical and research settings. Without realistic tissue-mimicking models, radiologists, technologists, and researchers face challenges in learning optimal acquisition protocols and interpreting quantitative data.
Multisite MRI Intravoxel Incoherent Motion Repeatability and Reproducibility across 3 T Scanners in a Breast Diffusion Phantom: A BReast Intravoxel Incoherent Motion Multisite (BRIMM) Study
Please join us for our upcoming user group sessions! We’ll be discussing MR-Linac, Diffusion, Repeatability, and Relaxometry.
BOULDER, Colo., Nov. 26, 2025 /PRNewswire/ — CaliberMRI, an industry leader in standardizing Magnetic Resonance Imaging (MRI), announced the release of a new quantitative MRI phantom compatible with the Medium ACR phantom. CaliberMRI’s qDisc (quantitative Dual Imaging Standardization Compartment) Model 141 allows sites to baseline T1, T2, ADC, and Proton Density in a single slice when scanning the Medium ACR phantom. The qDisc includes the Company’s patented MR readable LC Thermometer and is supported by qCal-MR®, an automated QA/QC analysis software. “This offering provides a practical option for gathering important quantitative metrics during routine scans with an ACR phantom,” says William Hollander, CEO of CaliberMRI. “With the rise of quantitative MRI offerings, the qDisc can be used as a first step toward harmonization of MRI scanners and AI software for analysis”. Hollander added. This phantom is intended to complement CaliberMRI’s more complete phantom platform solutions.
Heading to RSNA? We’ll be exhibiting at Booth 7610 (North Hall Level 3) and would love to discuss QA/QC, AI/ML/DL testing and validation, R&D, and/or custom solutions. Our cloud-based software, qCal-MR, now supports more than 45 scanner makes and models on Canon, GEHC, Hyperfine, Philips, Siemens, and United Imaging Scanners. We’ll be showcasing our new products, and are available to discuss collaborations. Reach out if you’d like to set up a meeting.
Take a look at our word cloud: qMRI, imaging, diffusion, T1, T2 ADC Mapping! Reproduciblity! QA/QC! Repeatability, Reproducibility, QA/QC!
Join us for Session 2: Tuesday, June 24th, 9:00 AM (MDT). To sign up or for login details, please email info[at]qmri.com.
