ISMRM Workshop on Motion Correction in MRI & MRS
|This workshop will explore the effects of motion on clinical and research scans. There will be emphasis on the significant cost of motion damage in clinical scans to radiology departments, as well as the substantial motion‐induced bias and possible erroneous conclusions based on motion‐affected research scans.
Motion damage will be assessed in terms of the images themselves and based on motion measured using tracking techniques. Understanding image artifacts using simulations and processing images to remove the artifacts will be considered. Most of the workshop will be devoted to learning about the latest techniques of motion detection and correction (prospective and retrospective). Intrinsic (self‐navigating and navigator‐based techniques) and extrinsic approaches (external tracking systems such as RF markers, cameras and other sensors) will be considered, and hybrid approaches (prospective and retrospective, navigator and external tracker) will also be discussed. Secondary effects of motion beyond simple changes in position (spin history and position‐dependent B0 and B1 changes) will be considered.
There will be discussion of specific solutions within the industry with manufacturers. The research community has developed a wide range of approaches that are not incorporated in any product. We will also invite representatives from the growing group of tracking device manufacturers to participate, and encourage a discussion about interfacing these devices with the standard scanners.
This workshop is designed for new MR scientists interested in learning and becoming involved in motion correction; experienced researchers interested in meeting with fellow researchers to learn and share cutting- edge techniques for motion correction; clinicians interested in applying the latest correction methods to solve their motion problems; researchers interested in how motion affects their research and how they can reduce or eliminate bias in their research conclusions; and industry representatives wanting to discuss the integration of tracking hardware with the standard MR platforms.
