Magnetic resonance visible labels and markers for encoding information
Systems and methods for manufacturing and using magnetic resonance (“MR”) visible labels or markers to encode information unique to the subject or object being imaged by a magnetic resonance imaging (“MRI”) system are provided. The use of such MR-visible labels or markers enables unique information associated with the subject or object being imaged to be encoded into the images of the subject or object. This information can be used to anonymize protected health information (“PHI”); to provide detailed information about a surgical simulation device, quality assurance phantom, or the like; to provide spatial orientation and registration information; or so on.
1. A magnetic resonance visible label, comprising:
a substrate having a first side, a second side, and magnetic resonance properties;
a plurality of indicia disposed in relation to the first side of the substrate, the indicia comprising a surface area and having magnetic resonance properties distinct from the magnetic resonance properties of the substrate such that the plurality of indicia are imageable with a magnetic resonance imaging (MRI) system,
the plurality of indicia are arranged in a pattern comprising a plurality of line segments encoding information relating to an object imageable with the MRI system,
the information comprising spatial orientation information defining a spatial orientation of the magnetic resonance visible label and instructions for automatically processing a plurality of MRI images of the object, and
the instructions comprising instructions for co-registering the plurality of MRI images using the spatial orientation information and for automatically directing the MRI system to image the object at an existing segmented area of interest,
Multiple telephone call attempts were made to Applicant's representatives of Record, May Lin DeHaan and Thanh Vuong, but no response was received regarding authorization for the Examiner's amendments.
2. The label of claim 1 , further comprising an adhesive layer coupled with the second side of the substrate.
3. The label of claim 1 , wherein the plurality of line segments comprises a plurality of fixed length line segments.
4. The label of claim 1 , wherein the plurality of line segments forms a barcode.
5. The label of claim 1 ,
wherein the plurality of indicia comprises at least one of a gel and an ink disposed in relation to the first surface of the substrate, and
wherein the plurality of indicia forms a quick response (QR) code and a bar code.
6. The magnetic resonance visible label as recited in claim 1 , further comprising a foil layer coupled to the second side of the substrate, and wherein the plurality of indicia are formed as comprises a plurality of cuts in relation to the first side of the substrate.
7. The magnetic resonance visible label as recited in claim 6 , wherein the plurality of cuts in the first side of the substrate are formed using a laser.
8. The magnetic resonance visible label as recited in claim 6 , wherein the plurality of cuts in the first side of the substrate are formed using a die.
9. The label of claim 1 ,
wherein the object comprises a subject, and
wherein the pattern further encodes information relating to protected health information.
10. The label of claim 1 ,
wherein the object comprises a phantom, and
wherein the plurality of indicia are arranged in a pattern further encodes information relating to the phantom.
11. The label of claim 1 , wherein the information further comprises a unique identifier associated with data stored in a database.
