Publication Date: 2014-Mar-05
The IP.com Prior Art Database
The invention proposes a technique for preventing crashes or mismatch or hang in workflow states in a magnetic resonance (MR) system. The technique includes a transparent lock. An imaging device is locked using an external computer or system via remote calls over a network. The lock is transparent. The transparent lock is put in place and user is present at the imaging device. The external computer controls the imaging device. There is no un-intended interruption of a workflow. The screen is locked via structural viewer and analytical tool (SVAT) using xtrlock or transparent screen saver. Keyboard or mouse activities are locked. Unlock option is provided via SVAT and via a console upon preset user ID and password entry.
FIELD OF INVENTION
The invention generally relates to a magnetic resonance system and more particularly to a technique for preventing crashes or mismatch or hang in workflow states in a magnetic resonance (MR) system.
BACKGROUND OF THE INVENTION
Focused ultrasound (FUS) is a technology which provides advancement to the MR system. In the FUS technique, ultrasound is focused similar in a way as magnifying glass focuses light energy. The high ultrasound energy density at the focus area results in tissue heating.
As shown in FIG. 1, a phased array transducer electronically adjusts a focal location. The adjustment is done with help of MR patient table specialized for MRgFUS.
FIG. 2 and FIG. 3 depict the MR patient table. The MR patient table consists of power components and a cradle that houses a FUS transducer. A phased array transducer is housed in a sealed bath and is connected to a motion system.
Generally, users are instructed not to interact with a magnetic resonance (MR) system during a focused ultrasound (FUS) session. When the user is simultaneously operating the MR system and uses structural viewer and analytical tool (SVAT) to send commands to the MR system, crashes or mismatch or hang in workflow states occurs. In such situation, system is required to restart which results in downtime.
A conventional technique related to a method for adjusting an appearance of a cover of an electronic device. The cover is comprised of an electrochromic substance. The electrochromic substance is set to a substantially transparent state when the electronic device is in an active mode. The electrochromic substance is set to a substantially opaque state when the electronic device is in idle mode.
One of the other conventional techniques relates to an intelligent screen saver utility. The intelligent screen saver utility is based on absence of an operator rather than a predetermined time period for activation and detects presence of the operator for deactivation. The intelligent screen saver is transparent in use to the operator. The intelligent screen saver requires no touching of a keyboard or mouse movement to either prevent the activation or deactivation of the screen saver. The screen saver requires a camera to capture images. The images are grabbed and temporarily stored in a computer memory. When the difference between the grabbed images is big enough, presence of person is detected. When there is no big difference between grabbed images during a given time period, absence of person is detected. The presence status is utilized to control the status of the screen saver.
However, the conventional techniques do not relate to a system which prevents crashes or mismatch or hang in workflow states.
Hence, there is a need in the art for improved system which prevents crashes or mismatch or hang in workflow states.
