Abstract
The present disclosure provides magnetic resonance phantom imaging phantoms and method of assembling thereof. In one aspect, a magnetic resonance imaging phantom can include a plurality of modular components. The plurality of modular components can include a first modular component, a second modular component, a shell, and a lid. The second modular component can be different than the first modular component. The shell can be structured to receive at least one modular component. The lid can be attachable to the shell to enclose the at least one modular component received within the shell.
Core Innovation
A method is described for assembling a magnetic resonance imaging phantom from a kit by selecting at least two components for a first calibration, assembling the components into a first configuration, and performing the first calibration with the first configuration. The first configuration is then disassembled and at least two modular components are selected for a second calibration, where the second configuration is different from the first configuration, followed by performing the second calibration with the second configuration.
A magnetic resonance imaging phantom kit is described that includes a shell comprising shell interlocking features and modular components that each comprise interlocking features configured to interlock with the shell interlocking features in different configurations. The kit includes a first modular component and a second modular component that are different from each other, and at least one of the first modular component and the second modular component comprises a contrast insert configured to receive a contrast medium.
The kit and method support validation and calibration by using different configurations and selecting component sets to correspond to different calibration and acquisition needs. The modular components can be selectively arranged for acquiring imaging data in low-field strength magnetic fields generated by a magnet assembly, and the configurations are described as applicable to low-field magnetic field and ultra-low field magnetic field acquisition.
Claims Coverage
The independent claims cover 3 inventive features: sequential calibration from different kit configurations, an interlocking modular phantom kit with contrast insert and property validation, and low-field magnet assembly acquisition with the modular phantom kit.
Sequential calibration from different kit configurations
Selecting at least two components from a kit for a first calibration; assembling the at least two components to form a first configuration of the magnetic resonance imaging phantom; performing the first calibration with the first configuration; disassembling the first configuration; selecting at least two modular components from the kit for a second calibration; assembling the at least two modular components to form a second configuration, wherein the second configuration is different than the first configuration; and performing the second calibration with the magnetic resonance imaging phantom.
Interlocking modular phantom kit with contrast insert and property validation
A magnetic resonance imaging phantom kit comprising a shell comprising shell interlocking features; a first modular component comprising first interlocking features configured to interlock with the shell interlocking features in different configurations; and a second modular component different than the first modular component, the second modular component comprising second interlocking features configured to interlock with the shell interlocking features in different configurations, wherein at least one of the first modular component and the second modular component comprises a contrast insert configured to receive a contrast medium, and wherein the first modular component and the second modular component are selected for validation of two or more properties selected from geometric distortion, contrast, structure, signal-to-noise, resolution, and intracranial vascular flow.
Low-field magnet assembly acquisition with interlocking modular phantom kit
A magnetic resonance imaging phantom kit comprising a shell comprising shell interlocking features; a first modular component comprising first interlocking features configured to interlock with the shell interlocking features in different configurations; and a second modular component different than the first modular component comprising second interlocking features configured to interlock with the shell interlocking features in different configurations, wherein at least one of the first modular component and the second modular component comprises a contrast insert configured to receive a contrast medium, and wherein the first modular component and the second modular component are selectively arranged for acquiring imaging data in low-field strength magnetic fields generated by a magnet assembly.
Across the independent claims, the inventive scope combines kit-based interlocking phantom modularity with selecting different component sets to assemble different configurations and perform sequential calibrations, while enabling validation of selected MRI properties and supporting acquisition in low-field strength magnetic fields generated by a magnet assembly.
