Abstract
An X-ray device for carrying out X-ray scans is configured for a simplified procedure. The X-ray device has an image receptor which operates in conjunction with an X-ray generator to carry out X-ray scans of a patient, and a patient table. A tabletop of the patient table which is used to position the patient during the X-ray scans, is immovable in the table plane. Instead, the image receptor is disposed in a longitudinally and transversely movable manner relative to the tabletop parallel to the table plane.
Claims8
An X-ray device for a medical imaging system, the X-ray device comprising:
- an X-ray generator;
- an image receptor configured to operate in conjunction with said X-ray generator to carry out X-ray scans of a patient;
- a patient table having a tabletop for positioning the patient during the X-ray scans;
- said tabletop being immovably disposed in a table plane and said image receptor being mounted for movement in a plane parallel to said table plane in a longitudinal and transverse direction relative to said tabletop;
- said patient table including a motorized drive configured to move said image receptor based on a movement of said X-ray generator, such that movement of said image receptor tracks the movement of said X-ray generator based on a detected position of said X-ray generator;
- and
- said patient table additionally including at least one sensor configured to detect a position of the X-ray generator, and at least one controller configured to operate said motorized drive based on a signal from said at least one sensor.
A method for medical imaging, the method comprising the following steps:
- positioning a patient on a tabletop of a patient table, the tabletop being immovable in a table plane;
- moving an X-ray generator to a scanning position relative to the patient;
- moving an image receptor that is longitudinally and transversely movable relative to the tabletop parallel to the table plane to a scanning position relative to the X-ray generator:
- based on a movement of said X-ray generator, such that movement of said image receptor tracks the movement of said X-ray generator based on a detected position of said X-ray generator;
- the patient table including a drive for moving the image receptor, at least one sensor configured to detect a position of the X-ray generator, and at least one controller configured to operate the drive based on a signal from the at least one sensor;
- and
- carrying out an X-ray scan of the patient.
A computer program for medical imaging by means of an X-ray device, comprising non-transitory computer program instructions for moving an X-ray generator to a scanning position relative to a patient who is positioned on a tabletop of a patient table, said tabletop being immovable in a table plane, for moving an image receptor that is disposed movably in a longitudinal and transverse direction relative to the tabletop parallel to the table plane to a scanning position relative to the X-ray generator, wherein the patient table has a drive for moving the image receptor and wherein the image receptor is moved based a movement of the X-ray generator, such that movement of the image receptor tracks the movement of said X-ray generator based on a detected position of said X-ray generator determined using a signal from at least one sensor configured to detect the position of said X-ray generator;
- and for carrying out an X-ray scan of the patient when the computer program instructions are executed in a control unit of the X-ray device.
