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 […]
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.
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. […]
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
Join us for open office hours! Ask questions about your phantom, qCal-MR and meet others advancing quantitative MRI!
Please join us for our upcoming user group sessions! We’ll be discussing MR-Linac, Diffusion, Repeatability, and Relaxometry.
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
Take a look at our word cloud: qMRI, imaging, diffusion, T1, T2 ADC Mapping! Reproduciblity! QA/QC! Repeatability, Reproducibility, QA/QC!
Topic: Traumatic Brain Injury, the TRACK-TBI Study, Data, and Quantitative Imaging
Guest Speaker: Dr. Pratik Mukherjee MD, PhD, UCSF
Dr. Mukherjee is a Professor in Residence in the Department Radiology and Biomedical Imaging, Bioengineering, and he is an attending neuroradiologist at the University of California, San Francisco. He is the Director of the Center for Imaging of Neurodegenerative Disease (CIND) based at the San Francisco VA Medical Center. He also directs the Neural Connectivity Laboratory (NCL) at UCSF China Basin.
Dr. Mukherjee’s primary clinical research is the study of neurodevelopmental disorders and traumatic brain injury (TBI) using advanced neuroimaging and artificial intelligence/machine learning (AI/ML) technology. His research has been focused on technical development, neuroscience and clinical applications of advanced imaging methods for mapping structure and function of the human brain, especially diffusion MRI, which is a popular technique for assessing the development and integrity of white matter and for mapping axonal fiber pathways.
Scope: Dr. Mukherjee will discuss his work on traumatic brain injury with the TRACK-TBI trial and on advanced neuroimaging and artificial intelligence/machine learning (AI/ML) technology.
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).
CaliberMRI is excited to participate in Innosphere’s 2026 Life Sciences Incubator Startup.
