Title:
X-RAY CT DEVICE AND IMAGE NOISE REDUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2008/010512
Kind Code:
A1
Abstract:
Provided is an X-ray CT device capable of obtaining a tomogram of a high spatial
resolution n without increasing the system noise affect and dosage. The X-ray
CT device includes: an X-ray source emitting X-rays; an X-ray detection unit
having X-ray detection elements arranged in the channel direction for detecting
the X-rays which have passed through an examinee as attenuated data; a data synthesis
unit for combining the attenuated data of the X-ray detection elements in the
channel direction so as to acquire synthesized data; a data decomposing unit
for decomposing the synthesized data so as to acquire decomposed data on each
of the X-ray detection elements; and an image reconfiguration unit for reconfiguring
an image of the examinee by using the decomposed data.
