METHOD AND APPARATUS FOR DETECTING ABNORMALITY RELATED TO STRUCTURE, PERFUSION, AND FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for computed tomographic imaging, and particularly for highly detecting and diagnosing pulmonary abnormality. SOLUTION: The method for obtaining data includes a step of obtaining data related to a plurality of contrast media by scanning the pulmonary 22 of a patient by a multi-energy type computed tomography (MECT) system 10. The multi-energy type computed tomography (MECT) system includes: a radiation source; a radiation detector; and a computer connected to the radiation source and the radiation detector concerning the operation. The computer is adapted to receive data about a first energy spectrum of scanning the lung of the patient, receive data about a second energy spectrum of scanning the lung, form a first functional image using data about a first contrast medium and form a second functional image using data about a second contrast medium.
