Abstract

Utilizing present clinical scanners (Magnetic Resonance MR, Computed Tomography CT), various accessories (e.g. coils, cushions, phantoms, contrast agent injectors etc.) used during the scan are arranged - on the basis of knowledge and experience of the operator - in cuboids or similar devices. However, misplacement of the accessories leads to an undesirable delay in the scan. Also, some damage could be caused if the accessories are not kept in a proper way. Scan time, being increasingly expensive, needs intelligent placement methods for accessories within the scanner room. Mishandling of the coils could change the transmitter adjustments and lead to artifacts in images, for example. A new system consists of a multiple camera system with/without processor, active or passive markers and a projector attached with a laser pointer. The system makes use of change detection algorithms to observe the activity in the scanner room. The camera system records the frequency of use of every accessory in the scanner room and suggests the operator after a certain duration about a proper positioning of the objects. After a user-defined time interval, the system can suggest to the operator the repositioning of the accessories.

Method of Detection and Apparatus for an Optimal Positioning of Accessories

Utilizing present clinical scanners (Magnetic Resonance MR, Computed Tomography CT), various accessories (e.g. coils, cushions, phantoms, contrast agent injectors etc.) used during the scan are arranged - on the basis of knowledge and experience of the operator - in cuboids or similar devices. However, misplacement of the accessories leads to an undesirable delay in the scan. Also, some damage could be caused if the accessories are not kept in a proper way. Scan time, being increasingly expensive, needs intelligent placement methods for accessories within the scanner room. Mishandling of the coils could change the transmitter adjustments and lead to artifacts in images, for example.

A new system consists of a multiple camera system with/without processor, active or passive markers and a projector attached with a laser pointer. The system makes use of change detection algorithms to observe the activity in the scanner room. The camera system records the frequency of use of every accessory in the scanner room and suggests the operator after a certain duration about a proper positioning of the objects. After a user-defined time interval, the system can suggest to the operator the repositioning of the accessories.

The system is able to make a proposal to the user, if he should buy or rent an accessory in case it is used very often or rarely, respectively (consultancy for workflow improvement). Once placed in the correct position, the camera system can suggest to the operator about the fastest procedure to place the accessories. The system can make a search for a missing accessory within the scan room. As monitoring also leads to observations such as delay due to misplacement or fall of objects (in case they are not kept properly), the method suggests a design of special cuboids and hooks for the coils/cushions/phantoms to avoid fall or to minimize the effect of fall.

All objects being used in the scanner room are coded with b...
