11357467 · 2022-06-14 · ·

An x-ray imaging apparatus and associated methods are provided to execute multi-pass imaging scans for improved quality and workflow. An imaging scan can be segmented into multiple passes that are faster than the full imaging scan. Data received by an initial scan pass can be utilized early in the workflow and of sufficient quality for treatment setup, including while the another scan pass is executed to generate data needed for higher quality images, which may be needed for treatment planning. In one embodiment, a data acquisition and reconstruction technique is used when the detector is offset in the channel and/or axial direction for a large FOV during multiple passes.

X-RAY IMAGING APPARATUS

The present invention relates to an X-ray imaging apparatus which obtains an X-ray image of a subject placed between a generator and a detector by means of the rotation of the generator and the detector. The X-ray imaging apparatus comprises: the generator and the detector, which are disposed to face each other while having an object to be imaged therebetween, for irradiating and detecting an X-ray; a rotation drive unit for rotating the generator and the detector while having the object to be imaged therebetween; and a bed in which a first portion for supporting the object to be imaged is disposed between the generator and the detector. When the height of at least one from among the generator and the detector is T1, the height of the other is T2, and the height of the first portion is T3, said T1, T2, and T3 are T1>T3>T2.
