Abstract
A method of computed tomography (CT) perfusion imaging includes: obtaining perfusion data by using a CT device to scan a present perfusion subject; performing calculations of the perfusion data by using two perfusion calculation methods to obtain perfusion parameters of each of said two perfusion calculation methods as initial perfusion parameters of each of said two perfusion calculation methods; performing calculations by using the initial perfusion parameters based on weights of said two perfusion calculation methods to obtain target perfusion parameters; and forming a target perfusion image of the present perfusion subject according to the target perfusion parameters.
