Abstract

A user interface (UI) for magnetic resonance imaging (MRI) protocol selection is proposed. Body profile or scout images are reconstructed in saggital and coronal plane and used to obtain symbolic anatomy structures' positions. The symbolic anatomy structures include head top, chin, two shoulders, lung profile, root of two thighs and two feet among others. Using the symbolic structures' positions a patient's entry and position is determined, for example head first or feet first and supine or prone respectively. Such automatic determination using symbolic structures' positions helps eliminate clicks on UI for MRI protocol selection, for example clicks for input of patient entry and position and anatomy selection. Further, cursor placement on the scout images is used for anatomy selection followed by a few clicks to select site and imaging protocols from a list or folder of protocols displayed in the UI. Reducing the number of clicks in turn increases productivity by making protocol selection efficient.

IMPROVED USER INTERFACE (UI) FOR MAGNETIC RESONANCE IMAGING PROTOCOL SELECTION

BACKGROUND

 

The present disclosure relates generally to magnetic resonance imaging (MRI) and more particularly to an improved user interface for MRI protocol selection.

There are various kinds of user interfaces (UIs) for MRI systems, which are routinely used by operators to carry out an examination procedure and image processing. The UIs enable protocol selection of the examination procedure for each patient. Protocol selection includes input of different information and numerous parameters via the UI.

 

However, conventional UIs for protocol selection are inefficient and complicated. Some conventional UI are inconsistent with respect to kind of imaging being carried out by the MR system. For example, while the MR system caters to global imaging, the UI associated is not efficient for global imaging protocols. In some conventional UIs protocol selection is cumbersome, which makes number of clicks required to select the protocol high.

Another challenge in conventional UIs is language customization. Some conventional UIs do not display characters in local language understood by operators and instead display English characters.  Such inefficiencies of foreign language display and high number of clicks in UIs affect throughput and productivity of the MRI system adversely.

It would be desirable to have an improved user interface for MRI protocol selection.

DETAILED DESCRIPTION

A user interface (UI) for magnetic resonance imaging (MRI) protocol selection is proposed. An MRI procedure acquires coronal localizer images during movement of a cradle towards the isocenter. A sensitivity map of the current connected coil also is acquired. Subsequently, as depicted in Figure 1 body profile images are reconstructed in saggital and coronal plane.

Figure 1

Based on the acquired three-plane body profile data, symbolic anatomy structures’ positions are obtained. The symbolic anatomy structures include head top, chin, two shoulders, lung profile, root of two thighs and two feet among others. Using the symbolic structures’ positions a patient’s entry and position is determined, for example head first or feet first and supine or prone respectively. Such automatic determination using symbolic structures’ positions helps eliminate clicks on UI for MRI protocol selection, for example clicks for input of patient entry and position and anatomy selection.
