Patent Issued for Patient Table System for Medical System for Medical Applications and Associated Medical Imaging Device

February 5, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- A patent by the inventor Lakshminarayanan, Ramanan (Karnataka, IN), filed on June 22, 2011, was published online on January 21, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8633827 is assigned to General Electric Company (Schenectady, NY).

The following quote was obtained by the news editors from the background information supplied by the inventors: "Embodiments of the present invention generally relate to a patient table system for medical applications comprising a table top and more particularly to a patient table system which ensures safety of patients lying on the table top.

"Embodiments of the present invention are also related to an imaging medical system comprising a patient table system and to a method for preventing the breakage of the table top in a patient table system.

"In most medical imaging systems, such as MRI, CT scan, or X-ray imaging devices, a patient 4 is asked by a medical practitioner to lie on a table top 2 of a patient table system 1, as depicted in FIG. 1. While lying on said table top 2, the patient undergoes medical imaging analysis.

"The patient table system 1 generally comprises means for moving the table top 2, such as elevation, rotation, tilting, longitudinal, and lateral moving means.

"Usually, the table tops are stiff plate-like members, in a composite material.

"In general, the table top 2 is supported by a table base 17 at one end, wherein the table base 17 is a supporting unit underneath the table top 2, while the other end of the table top 2 is a cantilever zone 12 which is not supported by any mechanical structure.

"The cantilever zone 12 is not supported by any mechanical structure in order to avoid the creation of image artifacts. The cantilever zone 12 is thus structurally weaker than the rest of the table top.

"When the patient lies on the table top 2, mainly on the cantilever zone 12, he exerts a pressure on the table top 2 due to his weight. Table tops are in general designed to resist to predefined mechanical constraints.

"However, it can occur that the table top 2 breaks under the weight of the patient, which can lead to the fall of the patient and to patient injuries.

"In order to ensure the patient safety in all circumstances, it would be preferable to avoid these situations.

"Hence, there is a need for a reliable and flexible solution than can prevent the patient from breaking the table top in medical imaging systems."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "In one embodiment, a patient table system for medical applications is provided. The table system comprises: a table top; at least one sensor configured to measure information representative of a pressure exerted by a patient on the table top when the patient is in a lying position; and a safety detector configured to compare the measured information with reference data of the table top mechanical resistance and to provide an alert depending on the result of the comparison.

"In an alternate embodiment, a medical imaging system is provided. The medical imaging system comprises a patient table system, the patient table system comprising: a table top; at least one sensor configured to measure information representative of a pressure exerted by a patient on the table top when the patient is in a lying position; and a safety detector configured to compare the measured information with reference data of the table top mechanical resistance and to provide an alert depending on the result of the comparison.

"In an alternate embodiment, a method for preventing the breakage of a table top in a patient table system for medical applications is provided. The method comprises: measuring information representative of a pressure exerted by a patient on the table top when the patient is in a lying position with at least one sensor of the patient table system; comparing the measured information with reference data of the table top mechanical resistance with a safety detector; and providing an alert with the safety detector depending on the result of the comparison."
