Embodiment

[0113] Example: Multi-contrast QR code

[0114] Markers as discussed above can encode several types of information. The required number of marker states can be estimated as the product of the following quantities, giving approximately 10 25 .

[0115] Patient identifiers unique to all humans in a few decades (10 times the world's population):

[0116] 10 11

[0117] Typically up to 10 scans are done, where each scan requires a scan protocol and FOV:

[0118] FOV relative to marker position (xmin=-20, xmax=20, ymin, ..., range=±1000mm):

[0119] Scan protocols from the list of MR and CT protocols:

[0120] Patient conditions can be coded individually for security:

[0121] For example: critical clinical status, implants, pediatric / psychotic / …, overall health, breath-hold duration, be sedated, special attention (by robot),

[0122] Hash function / checksum used to ensure data integrity with 0.1% fuzziness:

Abstract

The present invention relates to a patient marker (10). The marker is configured to be placed on or inside a patient. The marker comprises a specific structure (20). When the marker is placed on or inside the patient, and the patient is positioned at least partially within an image acquisition unit of an imaging system, the marker is configured such that an image acquired by the imaging system comprises image data of the specific structure of the marker. The marker is configured such that image data of the specific structure of the marker comprises information usable to identify the marker. The marker is configured such that image data of the specific structure of the marker comprises information usable to define at least one parameter relating to an examination of the patient.

Description

technical field [0001] The present invention relates to patient markers, imaging systems, and methods of imaging patients using imaging systems. Background technique [0002] US 2014 / 270067 A1 relates to a radiographic marker. The marker includes a first portion of radiolucent material including a first radiopaque pattern. The first portion is configured to be positioned on a first surface of an imaged subject during use. The marker also includes a second portion of radiopaque material that includes a second radiopaque pattern that is visually distinguishable from the first radiopaque pattern. The second portion is configured to be positioned on a second generally opposite surface of the object during use. The first and second radiopaque patterns produce corresponding first and second shadows on the radiograph when radiant energy is emitted and passed through the first portion, the object, and the second portion to produce a radiograph. Based on the fact that the first r...
