Brain perfusion imaging detection device and method based on magnetic resonance

The invention relates to the technical field of medical equipment, and discloses a brain perfusion imaging detection device based on magnetic resonance. The brain perfusion imaging detection device comprises a nuclear magnetic resonance imager, wherein a detection channel is arranged on the nuclear magnetic resonance imager. According to the invention, a bed body rotates under the driving by a rotating mechanism, a patient gradually rotates to a horizontal state along with the rotation of the bed body, then the bed body is driven by the driving mechanism to move towards the nuclear magnetic resonance imager, and the output end of the rotating mechanism is gradually separated from the bed body along with the gradual movement of the bed body towards the nuclear magnetic resonance imager, so the body of the patient can completely enter the nuclear magnetic resonance imager to be detected; and after detection is completed, the bed body is driven by the driving mechanism to move in a direction away from the nuclea
