CaliberMRI announces release of the qDisc, a new quantitative MRI phantom for added functionality of the Medium ACR Phantom
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.

November 18th – User Group Session | Traumatic Brain Injury, the TRACK-TBI Study, Data, and Quantitative Imaging | Dr. Pratik Mukherjee (UCSF)
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.
