Spirit mri mass control model, which is an advanced mri qa quality assurance (qa) module, is designed to simplify scanner validation, quantitative mri (qmri) accuracy check and space malformation assessment。
The spirit mri qa module, which draws on the advice of top mri physicists and is carefully designed to achieve seamless integration, is an essential tool for medical institutions, research institutions and video centres。

Final mri qa module Multiparameter test in one Spirit combines nist calibration, si retroactive t1, t2 and adc tubes with geometric features to achieve a full mri scanner qa。 Advanced slice thickness and teratometry Spirit provides a high-precision profile analysis of the slices with precise cross-sections at the physicomodel centre。 Optimised for even field imaging The spherical design ensures an excellent field balance and minimizes the field imbalance, leading to consistent and reliable results。 Multipurpose multiposition sampling The same t1/t2 values are distributed in multiple locations and can easily detect changes in b1 and b0 fields。 Customise the qa for brain imaging The body-mode cavity contains liquid formulations that achieve optimal background signals, magnetic ratio matching and coil loads。 |
| Altitude clear reference points to ensure space accuracy Spirit uses 52 mri visible reference points, arranged in a straight-line cartesian grid that allows for accurate spatial malformations analysis。 Mri resolution test Grids with resolution ranging from 0. 5 to 3. 0 mm in multiple directions are used to assess the ability of image collection to interpret fine details。 It's seamlessly compatible with mainstream mri systems Spirit uses universal design that is compatible with the headring of most mri manufacturers and integrated into standard mri workflows。 Strong, durable and renewable placement The dedicated frame ensures consistent positioning within the mri head coil, thus achieving repeatable high accuracy tests。 Image for the future Advanced software for automatic slice contour analysis, space malformation mapping and signal level extraction (wip) |
