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
Happy 75th Birthday to our CEO and founder Bill Hollander! A scientific instrument maker, Bill started his career at JILA in 1979 (a joint institute between National Institute of Standards and Technology (NIST) and University of Colorado Boulder).
Please join us for our upcoming user group sessions! We’ll be discussing MR-Linac, Diffusion, Repeatability, and Relaxometry.
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 Session 2: Tuesday, June 24th, 9:00 AM (MDT). To sign up or for login details, please email info[at]qmri.com.
Topic: The variability of Mean ADC Measurements with Simultaneous Multi-slice Imaging in a NIST/QIBA/CaliberMRI Diffusion Phantom
Guest Speakers: Dr. Ryckie Wade, PhD, and Matthew Marzetti, MsC, University of Leeds, United Kingdom
CaliberMRI is excited to participate in Innosphere’s 2026 Life Sciences Incubator Startup.
Multiparametric Tissue Mimics for Breast Imaging and Medical Device Testing
Stephen Russek, Todor Karaulanov (presenter), Willaim Hollander, Chamni Jayarathna, Callie Weiant, John Wenzel, Shannon John
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.
Important Meeting Alert – Please Join the ConversationNIST/NIBIB Symposium on Medical Metrology and Standards for American Healthcare and Commerce Medical Imaging, Devices, Diagnostics The Question: What future medical measurements, metrology, and standards should be prioritized to support U.S. Healthcare?
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
Work spanning 2 years, 9 scanners at 5 centers to evaluate repeatability and reproducibility of quantitative ADC measurements in preparation for longitudinal clinical trials incorporating quantitative ADC as a biomarker of cancer, using the qMRI room temperature ADC phantom. Study results and discussion of the utility of the phantom.
We are excited to share our 2025 User Group Sessions! Mark your calendars: SESSION 1: Tuesday, April 1st, 9:00 a.m. MDT Topic: Annual Physics Testing with the CaliberMRI Mini Hybrid Phantom. Guest Speaker: Norman P. Sipp, MS DABR, Chief Diagnostic Medical Physicist: Ascension Seton Network-Austin, TX SESSION 2: Tuesday, June 24th, 9:00 a.m. MDT Topic: […]
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.
Join us for open office hours! Ask questions about your phantom, qCal-MR and meet others advancing quantitative MRI!
