Abstract

This invention proposes a technique that provides solution to problems of MRPET and MRI systems, such as, prescribing correct extents for patients moving during an exam, correctly covering extents for all substations for whole body localizer (WBL) scan and inability to observe extents on actual patient photo itself. The technique provides solution in two stages. The first stage displays prescription of each sub-station on main WBL task. In the second stage, the technique utilizes a live localizer to observe extents on actual photo.

GRAPHICAL PRESCRIPTION OF WHOLE BODY LOCALIZER FOR MRPET AND/OR MRI SYSTEMS

FIELD OF INVENTION

The invention generally relates to magnetic resonance positron emission tomography (MRPET) and magnetic resonance imaging (MRI) system and more particularly to a technique for providing graphical prescription of whole body localizer for MRPET and MRI systems.

BACKGROUND OF THE INVENTION

Generally, magnetic resonance (MR) system user interface includes several user interface (UI) windows. The UI windows capture several kinds of patient prescription and image information. Significant amount of prescription information is captured through graphical interface, which is known as graphic Rx. A conventional technique includes 3-plane localizer. 3-Plane localizer are obtained and subsequent prescription are done on 3-Plane localizer. For whole body localizer (WBL) main task, no graphical prescription is shown and it is not possible to see extents of each sub-station. Even if user observes extents of all substations on WBL main task, user still does not know if prescription is covering whole patient or not. A user relies on experience, manual calculation, and retries to acquire relevant WBL. Also, user is not able to observe overlap of each substation on main WBL task. User is required to re-scan in case patient moves. FIG. 1 depicts conventional WBL main task graphic Rx.

However, conventional technique is prone to errors and poor user experience resulting in low throughput.

Hence there exists a need for a technique to provide user friendly mean of prescribing WBL and prescription for other applications.

DETAILED DESCRIPTION OF THE INVENTION

This invention proposes a technique that provides solution to problems of MRPET and MRI systems, such as, prescribing correct extents for patients moving during an exam, correctly covering extents for all substations for whole body localizer (WBL) scan and inability to observe extents on actual patient photo itself. The technique provides solution in two stages.

In the first stage, WBL localizer controller component is used for calculating extents. The WBL localizer controller uses already scanned conventional 3-Plane localizer. When WBL main task is setup, MRPET and/or MRI system display localizer image instead of blank viewports. When user selects number of intended stations as part of whole body scan or enters 'S/I start loc' or 'S/I end loc', inter...
