Abstract

The invention relates to an opto-acoustic brain function imaging method. The method realizes imaging of brain blood vessel structure distribution observation and function monitoring via the opto-acoustic tomographic image of the cortex blood vessels. Brain damage and cerebral hemorrhage variation degree can be monitored, and the parameters such as cerebral blood flow, brain oxygen consumption and brain oxygen saturation etc can be reflected via the blood vessel form distribution, blood diameter variation and opto-acoustic signal intensity variation of blood vessels. The laser generation component, acoustic signal acquisition component and computer among the devices realizing the mentioned method are electrically connected in turn. The rotary scanning mechanism is electrically connected with the computer. The sample fixation components are connected with the acoustic coupling components in turn. The invention is characterized by convenient operation and sensitive and quick performance, can make imaging analysis of blood vessels without damage, and then monitor brain function, which can thus provide imaging basis for brain function judgment.

Description

technical field

[0001] The present invention relates to medicine and medical devices. In more detail, it is a method of photoacoustic brain functional imaging.

[0002] The invention also relates to a device for carrying out the above-mentioned method. Background technique

[0003] Brain functional imaging is a new medical imaging that uses brain local imaging technology to observe and analyze the high-level functional activities of the brain without any damage, and then evaluate the brain function.

[0004] The first thing in brain science research is experimental research, especially the study of the dynamic process of the living brain under non-invasive conditions. Currently, methods commonly used in brain functional imaging include single photon emission computed tomography (SPECT: Single Photon Emission Computed Tomography), positron emission tomography (PET: Positron Emission Tomography) and nuclear magnetic resonance functional imaging (f...
