Abstract
Systems, devices and methods for performing a magnetic resonance imaging scan of a patient. For example, a method of performing a magnetic resonance imaging scan on a patient can include monitoring a physiological signal level of the patient, analyzing the monitored physiological signal level, and providing instructions to the patient and/or changing the environmental conditions exposed to the patient. The instructions and/or the change of the environmental conditions of the patient can be based on the monitored physiological signal level. The instructions can include an acoustic command and/or a visual command. The changing of the environmental conditions can include visual simulation, acoustic stimulation and/or air conditioning change.
Claims10
A magnetic resonance imaging system for performing a magnetic resonance imaging scan adaptively optimized to an imaged subject, the system comprising:
- a sensor configured to sense a physiological signal of the subject;
- a speaker configured to provide pre-recorded or synthesized instructions to the subject;
- and
- a processor configured to:
- analyze the sensed physiological signal to determine instructions to guide the subject to maintain a preferred physiological condition;
- dynamically control the speaker to deliver the pre-recorded or synthesized instructions to the subject to enter or maintain the preferred physiological condition;
- determine an ability of the subject to maintain the preferred physiological condition;
- dynamically change a scan protocol based on the ability of the subject to maintain the preferred physiological condition;
- and
- control the magnetic resonance imaging scan according to the changed scan protocol.
A magnetic resonance imaging system for adaptively performing a magnetic resonance imaging scan optimized to an imaged subject, the system comprising:
- a sensor configured to sense breathing of a subject and generate a physiological signal indicative of breathing motion of the subject;
- a speaker configured to acoustically deliver information to the subject during magnetic resonance imaging;
- and
- a processor configured to:
- prior to imaging the subject, controlling the speaker to emulate acoustic sounds of a magnetic resonance imaging scan and deliver breathhold instructions to the subject and concurrently analyze the physiological signal to determine an ability of the subject to maintain a breathhold;
- based on the determined ability of the patient to maintain a breathhold, selecting an initial scan protocol;
- control a magnetic resonance imager to implement the magnetic resonance imaging using the initial scanned protocol;
- during the magnetic resonance imaging, controlling the speaker to deliver pre-recorded or synthesized instructions to the subject to commence a breathhold and to deliver pre-recorded or synthesized messages to the subject encouraging the subject to maintain the breathhold, and providing pre-recorded or synthesized instructions to the subject to release the breathhold;
- during the scan, monitoring the physiological signal to reassess the ability of the subject to maintain the breathholds;
- in response to a change in the ability of the subject to maintain the breathhold, selecting a new scan protocol based on the changed ability;
- and
- controlling the magnetic resonance scanner to continue imaging the subject with the new scanned protocol.
