Automated sequential planning of mr scans

Abstract

A method of acquiring at least one clinical MRI image of a subject comprising the following steps: acquiring a first survey image with a first field of view, the first survey image having a first spatial resolution, - locating a first region of interest and at least one anatomical landmarks in the first survey image, determining the position and the orientation of the first region of interest using the anatomical landmarks, the position and the orientation of the first region being used for - planning a second survey image, - acquiring the second survey image with a second field of view, the second survey image having a second spatial resolution, the second spatial resolution being higher than the first spatial resolution, generating a geometry planning for the anatomical region of interest using the second survey image, - acquiring a diagnostic image of the anatomical region of interest using the geometry planning.

Description

technical field [0001] The present invention relates to a method, device and computer program product for automatically acquiring clinical MRI image data. Background technique [0002] MRI scanners use huge static magnetic fields to align the nuclear spins of atoms as part of the process of producing images of the inside of a patient's body. This huge static magnetic field is called the B0 field. [0003] During an MRI scan, radio frequency (RF) pulses generated by a transmitter coil perturb the local magnetic field, and receiver coils detect RF signals emitted by nuclear spins. These RF signals are used to construct MRI images. These coils may also be referred to as antennas. Alternatively, the transmitter and receiver coils may be integrated into a single transceiver coil that performs both functions. It should be understood that use of the term transceiver coil also relates to systems using separate transmitter and receiver coils. This transmitted RF field is called ...

AI Technical Summary

Problems solved by technology

The difficulty is that clinical images obtained by different operators will have different levels of quality

Furthermore, when setting the position and orientation of the stack of slices is performed manually, it is difficult to achieve reproducibility of clinical MRI images in e.g. subsequent procedures

When operators produce clinical images of poor quality, they will need to be redone

This is of course expensive for the hospital and adds to the cost of MRI examination of the patient
