Abstract

In this chapter we present a new approach to reduce the examination time of MRI systems. The time reduction is accomplished by dividing MRI scans into segments, which are intermixed to reduce the MRI examination time. The intermixing algorithms are based on a scheduling framework. First, the concept of multiple scan sets (ExamCards) is introduced. Then an explicit definition of the algorithms for different duty cycle limitations is presented. Next, the results of application of the algorithms to the Philips Healthcare routine examinations are provided. Finally, the MRI experiments that employs this time reduction approach are described. These algorithms are robust with respect to MRI hardware changes, thus they can be utilized to improve overall evolvability of the MRI system.

Notes

  1. 1.

    Duty cycle is the fraction of time that MRI system is in an ‘active’ state (e.g. performing an examination).
