Title:
MAGNETIC RESONANCE IMAGING APPARATUS FOR ANGIOGRAPHY
Document Type and Number:
WIPO Patent Application WO/2018/080294
Kind Code:
A1
Abstract:
The present invention relates to a magnetic resonance imaging apparatus for an angiography, having an RF coil, applying an RF pulse through the RF coil to an object, and generating blood vessel data by receiving an MR signal from the object through the RF coil, the magnetic resonance imaging apparatus comprising: a signal transmission and reception unit including an RF transmission and reception unit including a signal transmission unit for applying the RF pulse to the RF coil and a signal reception unit for receiving, from the RF coil, the MR signal containing characteristics of a TOF signal and a bSSFP signal, and a gradient magnetic field amplifier for controlling a spatial encoding gradient magnetic field; and a control unit including an RF control unit for generating the RF pulse so as to acquire the TOF signal and the bSSFP signal and transferring the generated RF pulse to the signal transmission unit of the RF transmission and reception unit, and a gradient magnetic field control unit for generating the gradient magnetic field control signal and transferring the generated gradient magnetic field control signal to the gradient magnetic field amplifier. As a result, the RF pulse, which simultaneously includes a TOF and a bSSFP, is applied to a blood vessel and a blood stream such that a blood vessel image can be accurately acquired by receiving a blood vessel image signal having a high intensity, even if the blood stream is slow, thereby reducing a time for acquiring the blood vessel image from the magnetic resonance imaging apparatus.
