Examination table of medical imaging system
This disclosure relates to an examination table of a medical imaging system comprising a tabletop, a table column supporting the tabletop, and a translation system. The translation system, which is configured to at least make the tabletop longitudinally translate with respect to the table column, comprises a guiding part and a driving part, where both the guiding and driving parts may be fully integrated in said table column.
1. An examination table for a medical imaging system, comprising:
a tabletop defining a patient support surface and opposing lateral edges;
a table column supporting said tabletop; and
a translation system forming part of the column and configured to effectuate a longitudinal translation of said tabletop with respect to said table column, said translation system comprising a pair of guide rails laterally spaced relative to the tabletop, each of the pair of guide rails defining a respective groove through which the tabletop translates, and two sets of motorized rollers, each set comprising two opposing rollers rotatable about a vertical axis relative to the patient support surface and configured to cooperate directly with the opposing lateral edges of said tabletop.
2. The examination table according to claim 1 , wherein said tabletop includes barcodes which are printed on its external surface, each of which are representative of a respective longitudinal position of the tabletop relative to with respect to said table column, the translation system configured to detect the barcodes and to stop longitudinal translation of the tabletop at any of the longitudinal positions associated with their respective barcode.
3. The examination table according to claim 1 , wherein said translation system is configured to cooperate exclusively with the opposing lateral edges of said tabletop.
4. The examination table according to claim 1 , wherein the opposing rollers in each set are conical shaped and positioned so their respective vertexes face each other so as to define a respective v-shaped recess configured to cooperate with a respective one of the opposing lateral edges of said table top.
5. The examination table according to claim 4 , wherein the two sets of motorized rollers cooperate with said tabletop lateral edges by direct friction between each other.
6. The examination table according to claim 4 , wherein each of said tabletop lateral edges defines a triangular convex shape configured to fit into and cooperate with a corresponding one of the v-shaped recess formed by the opposing rollers in each of the two sets of motorized rollers.
7. The examination table according to claim 1 , wherein said translation system comprises a motor fully integrated in said table column, said motor configured to drive rotation of the two sets of motorized rollers.
8. The examination table according to claim 1 , wherein said tabletop comprises an inner foam surrounded by an outer casing comprising no other protruding part other than its defining edges, said outer casing including one or more carbon fiber sheets, and said tabletop lateral edges present an outer casing which is structurally more rigid relative to the rest of said tabletop.
