Abstract

Presently in any medical intervention, the accuracy of making the right use of objects as scissors, knives, gloves, medicaments, bandages, needles, contrast agents, threads etc. depends upon the expertise of the surgeons/operators. The complexity of the process in an OR (Operating Room) increases when a certain compatibility is also necessary, e.g. using a MR (Magnetic Resonance) scanner during an intervention. In some cases, the patient is scanned several times during the surgery, and every time the operator has to make sure that nothing non-compatible to the MR scanner is left on the patient's body. Metallic objects in the vicinity of the MR scanner not only could lead to misleading artifacts in the images, but also could be extremely dangerous to the patient. Scanner time and operator time, being increasingly expensive, lead to an urgent need of a supervisory system to make a search for non-compatible objects in the patient's body. Within the present scenario, about 50% of the clinical trials use contrast agents. In usual clinical routine procedures, the selection of contrast agent is done manually, based on the requirement for the patient diagnosis. A new system gives a mechanism to detect objects within the patient's body during a medical intervention: All objects used in the OR are registered and classified as disposable, non-disposable and objects that could be left inside the body after intervention. The encoded objects are kept on a table with specified slots. Whenever an object is used, a registration is performed. The transponders are detected by movable sensory mechanisms present on both sides of the patient table. The system makes use of wireless transmission (e.g. Bluetooth) and changing detection algorithms.

Presently in any medical intervention, the accuracy of making the right use of objects as scissors, knives, gloves, medicaments, bandages, needles, contrast agents, threads etc. depends upon the expertise of the surgeons/operators.

The operator has a possibility to select a region of interest in the display to make a more precise and faster search. The sensory mechanism registers the disposable objects thrown into the dustbin (e.g. glove...
