Abstract

A technique for artifact suppression in magnetic resonance (MR) images based on motion detection is proposed. The technique includes a subsystem including a motion detection system and an automatic voice based reminding system, coupled to a magnetic resonance imaging system. The subsystem monitors movement or motion in area where MR exam is being carried out, using a high density camera and automatically reminds a patient not to move using voice.

A TECHNIQUE FOR ARTIFACT SUPPRESSION IN MAGNETIC RESONANCE (MR) IMAGES BASED ON MOTION DETECTION

BACKGROUND

 

The present disclosure relates generally to artifact suppression in magnetic resonance (MR) images and more particularly to a technique for artifact suppression in MR images based on motion detection.

In Magnetic Resonance (MR) images, quality is often adversely affected by patient motion and a poor quality image presents the risk of misdiagnosis. The patient may move subconsciously or unconsciously due to various reasons such as discomfort and anxiety among others. Generally, different methods such as counseling the patient to stay still before the scan, flip-flop compensation and gated compensation are used to reduce these artifacts.

However, gated and flip-flop compensation methods are useful in removing artifacts due to regular motion. For irregular patient motion during the examination, in many instances a doctor or an operator monitor the patient on a video monitor and remind the patient regarding preventing movement via a microphone. Such monitoring and reminders during the examination is a load on the resources of the medical care-giving centers. 

It would be desirable to have to an improved technique for artifact suppression in MR images based on motion detection.

DETAILED DESCRIPTION

A technique for artifact suppression in magnetic resonance (MR) images based on motion detection is proposed. The technique includes a subsystem including a motion detection system and an automatic voice based reminding system, coupled to a magnetic resonance imaging (MRI) system. The subsystem monitors movement or motion in area where MR exam is being carried out and automatically reminds a patient not to move using voice.

As depicted in Figure 1, hardware of the subsystem includes a high definition (HD) camera, an image compressor, an embedded micro-controller unit (MCU), an automa...
