Abstract
A magnetic resonance imaging apparatus includes a data acquisition unit and an image generating unit. The data acquisition unit sets a delay time from a reference wave based on heart rate information or peripheral pulse wave information previously acquired from an object and acquires MR signals by an imaging scan with the set delay time in synchronized with a beat. The delay time represents a time phase of a data acquisition timing in imaging in synchronized with the beat. The image generating unit generates a blood flow image based on the magnetic resonance signals.
Claims23
A magnetic resonance imaging apparatus comprising:
- a data acquisition unit configured to set a delay time from a reference wave based on heart rate information or peripheral pulse wave information previously acquired from an object and acquire magnetic resonance signals by an imaging scan with the set delay time in synchronized with a beat, the delay time representing a time phase of a data acquisition timing in imaging in synchronized with the beat, and
- an image generating unit configured to generate a blood flow image based on the magnetic resonance signals.
A magnetic resonance imaging apparatus comprising:
