Patient table comprising a positioning system and method of using such a patient table

Research output: PatentPatent publication

Abstract

A patient table (1) usable in an X-ray image acquisition arrangement (100) is proposed. The patient table (1) comprises a table plate (3) being connected to a table base (5) via at least one movable joint (9), wherein the table plate (3) is movable using at least one actuator (11). In order to set or re-establish an accurate position/orientation of the movable table plate (3), the patient table comprises a positioning system including a first sensor arrangement (15) for providing position data of the at least one movable joint (9) and a second sensor arrangement (17) for providing position data of the table plate (3), e.g. by tracking at least one marker (21) attached to the table plate (3). Using such patient table (1) may allow for accurately automatically positioning the table plate (3). Furthermore, the accurate position data provided by the second sensor arrangement (17) may be used in a method for improved three-dimensional roadmapping.
