Multiple-energy X-ray imaging system and control method for the same

摘要

A multiple-energy X-ray imaging apparatus and a method obtain a plurality of X-ray images when the heart of a patient is in the same phase by measuring the electrocardiogram of the patient. A sensor is installed on a handle or a foot stool to measure the electrocardiogram when the patient grips the handle or makes contact with the foot stool without having to attach an electrode to the body of the patient, which removes the inconvenience in measuring the electrocardiogram.

主权项

1. A multiple-energy X-ray imaging apparatus comprising:
an X-ray generating unit configured to sequentially radiate X-rays starting from a first energy X-ray of first energy level to a nth energy X-ray of nth energy level; a power supply unit configured to supply the X-ray generating unit with power; a detector unit configured to detect the X-rays, which are radiated from the X-ray generating unit, and to convert the detected X-rays to electric signals; a handle mounted on the detector unit to be gripped by an object; a sensor unit installed on the handle to sense an electrocardiogram signal generated from the object; and a host computer configured to obtain X-ray images by performing control procedures such that each of at least one X-ray starting from a second energy X-ray to an nth energy X-ray is sequentially radiated upon generation of the electrocardiogram signal that has a same phase as the phase of the electrocardiogram signal provided at a point of time when an image based on the first energy X-ray is obtained.
