The CaliberMRI System Phantom Lite

Links cancer biomarkers to MRI image data

For MRI results to be beneficial to both researchers and patients, results must be accurate and reproducible. Standardization across all MRI sites and vendor scanners is essential for comparing results and compiling data. The CaliberMRI System Phantom Lite is the most comprehensive phantom for all your MRI calibration needs.
  • Maximum diameter: 194 mm
  • Contrast cells, 20 mm ID spheres: 14 spheres T1 spread (20ms-2s), 14 spheres T2 spread (8ms-800ms), and 14 spheres proton density
  • True dimensional/positional accuracy of +/- 0.1 mm on  all key elements
  • One resolution insert with hole/slot arrays
  • Wedges for slice profiling
  • Physical and MR key to precisely determine phantom alignment
  • B1 and B0 non-uniformity
  • Geometric linearity
  • Gradient amplitude
  • Slice profile and slice positioning accuracy
  • Landmark accuracy
  • System center frequency drift (short time duration)
  • Resolution, SNR
  • Accuracy and precision of T1, T2, and proton density measurements
