Calibermri 206-wall mammography, and calibermri 206-mammography mri quantitative modelling set standards for breast cancer treatment monitoring。
Complete quantitative parameter packages for adc and t1 standardization with real mammogram mri fat inhibition。
Develop with nist and ucsf。
Using the unique fat simulator developed by caliber mri in collaboration with the university of california san francisco and nist, breast fat is suppressed in mr imaging。
Standardized adc and t1 calibration
Calibermri's human tissue simulation solution was developed in collaboration with leading qmri researchers and scientists。
CoNtrast and diffusion are surrounded by a single shell filled with a fbg gap solution。
Assessment of mri properties:
B1 and b0 evenness, geometric linearity, gradient range
System centre frequency drift (short duration)
Resolution and snr
T1 survey accuracy
Observed proliferation factor (adc) precision
A comparison for t1 setting standardization noodles
The film-making side contains a series of fatty, dense fibre glands (fbg) tissues and pvp simulators, which contribute to fat inhibition and t1 mapping and standardization。
Four floors:
Fbg and fat analogue surrounded by fbg
Fbg and adc simulator (25% pvp)
Fat simulator surrounded by fbg
Fbg simulation surrounded by fat
For the adc standardized proliferation side
Diffusion side includes fat simulations and various pvp simulations, which contribute to adc mapping and standardization。
Adc simulator* surrounded by fbg
4x fat sample bottle
1x pure water & sample bottle
Space distortion array: ∅10 mm hole on 15 mm grid
Resolution array: holes in ismrm graphics ∅0. 5 mm to ∅1. 25 mm
Calibermri provides calibrated solution and tissue simulations for mri models, which are traceable, including through the complete si (if available)。
* the nominal value is taken at 3t below 20°c。
