Embodiment Construction

[0044] The near-infrared brain function detector provided by the present invention is combined with other instruments to realize multi-mode measurement synchronization devices such as figure 1 shown. The device includes other instruments 1 that need to be synchronized (such as fMRI instruments, PET instruments or EEG / ERP instruments), a near-infrared brain function detector 2, a control signal generation module 3, and a synchronization device loaded into the near-infrared brain function detector 2. Start the data acquisition module 4 and synchronously terminate the data acquisition module 5, the transmission module 6 of the control signal, and the square wave pulse signal capture module 7;

[0045] The control signal generation module 3 is used to generate a single square wave pulse signal for controlling the synchronization start measurement and the synchronization end measurement respectively, and the output ports of the two signals are named P1 and P2 in turn;

Abstract

The invention relates to a method and device for implementing measurement synchronization of near-infrared brain function detector. The device comprises a near-infrared brain function detector and at least one medical instrument with the exception of the near-infrared brain function detector, also comprises a control signal generating device and a control signal transmission module; the control signal generating module generates a synchronous starting measurement signal and a synchronous closing measurement signal; the control signal transmission module transmits the signal in shunt to the medical instrument and the near-infrared brain function detector; the near-infrared brain function detector is provided with a signal capturing module for capturing the signal, a synchronous starting data acquisition module and a synchronous closing data acquisition module, after capturing the signal, the synchronous starting data acquisition module and the synchronous closing data acquisition module respectively control the near-infrared brain function detector to start measurement and interrupt or stop measurement. The invention can enable the near-infrared brain function detector to perform multiple-mode measurement with other instruments synchronously, without changing the other instruments.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a method and a device for realizing measurement synchronization of a near-infrared brain function detector. Background technique [0002] Compared with the widely used brain function detection techniques - functional magnetic resonance imaging (fMRI), positron emission tomography (PET), electroencephalography / event-related potential technology (EEG / ERP), the emerging near-infrared brain function spectroscopy NIRS / fNIRI has the advantages of portability, low cost, high temporal resolution, and non-invasive detection. It has been widely praised in brain research and clinical detection. NIRS is near-infrared brain function spectroscopy, and fNIRI is a near-infrared brain function imaging instrument. The near-infrared brain function detector in the present invention includes both, represented by NIRS / fNIRI. [0003] With the increasing demand for the diagnosis and analysis of b...
