Spectronic Medical provides large field-of-view phantoms and evaluation software for geometric QA in any MRI based radiotherapy workflow
The Spectronic Medical GRADE phantom and evaluation software provides the ability to accurately assess system related geometrical distortions throughout the full field-of-view of MRI scanner. Never before has such powerful analysis been provided in a package that allows for daily usage in a routine clinical workflow.
Assessing the geometric integrity of an MRI scanner is of importance in many clinical applications. For instance, in radiotherapy the geometrical correctness of the images from which the treatment is planned is of high importance. For this reason, having robust quality assurance procedures to routinely verify the geometry of acquired MR images is essential to any hospital working with such applications.
The GRADE phantom is a light-weight (<10 kg) unit comprising around 1200 spherical markers specifically designed for MRI geometry distortion assessment. GRADE phantoms come in versions that are optimized for different MRI scanner models, to assure that markers are well-distributed across the full effective field-of-view. The purpose of the GRADE phantom is to allow geometry distortion assessment of the same types of images as are used in clinical applications. Thus, GRADE phantoms can be used with virtually any type of MR sequence.
Optimized for each MRI scanner model to provide full field- of-view coverage.
Built for daily quality assurance testing with ease of use in mind. Weighs less than 10 kg / 22 lb.
Fully automated software, returning a comprehensive evaluation report with diagrams and tables.
The GRADE evaluation software is accessed either through a web interface or through a software installed at the hospital. In the latter case MR images are directly sent from the MRI scanner to the software through standard DICOM communication, to enable seamless integration into any clinical workflow. MR images are processed by the GRADE evaluation software, which generates a PDF report that is provided back to the user.
GRADE Evaluation report
The evaluation report includes diagrams and tables to provide an analysis of the geometrical accuracy of the MRI scanner. The comprehensive report is targeted toward daily QA evaluation. For advanced users, there is an optional ability to also receive complete distortion vector fields for further analysis.
