Apparatus for capturing medical image and method of adjusting table thereof

摘要

A wireless device communicates with a medical image capturing apparatus to adjust a position of a table supporting an object to be imaged. An operator adjusts a position of the wireless device, the apparatus measures the wireless device's position, and adjusts the table based on the measured position. A method may include measuring distances between the wireless device and each of a plurality of respective detection units arranged along an axis. An axial distance may be measured between a reference point and the wireless device using measured distances and locations of the detection units relative to the reference point. The table is moved with respect to a gantry aperture of the apparatus based on the calculated axial distance. Controlled table movement may be movement into the gantry aperture and/or table height adjustment.

主权项

1. A method performed by an apparatus for capturing a medical image of an object to adjust a location of a table that supports the object, the method comprising:
measuring respective distances between a plurality of detection units arranged along an axis in a longitudinal direction of the table and an operator-adjustable wireless device; calculating an axial distance on the axis between a reference point and the wireless device using the measured distances and respective locations of the plurality of detection units relative to the reference point; moving the table with respect to a gantry aperture of the apparatus based on the calculated axial distance, wherein, the wireless device comprises a radio frequency identification (RFID) tag, the plurality of detection units comprises a plurality of RFID readers, and the measuring comprises measuring a distance between each of the plurality of RFID readers and the RFID tag by tracking transmission and reception times of signals exchanged between the RFID tag and the RFID readers.
