Multi-channel portable microwave scanning brain imaging device and method

Abstract

The invention relates to a multi-channel portable microwave scanning brain imaging device and method. The multi-channel portable microwave scanning brain imaging device comprises an elastic loading module, a coupling fluid storing module for storing coupling fluid, a vacuum negative pressure generating module for producing vacuum negative pressure, and a microwave signal processing unit, wherein the elastic loading module cooperates with the shape of the brain, consists of an arc-surface antenna array, a skull hood and a ventilation pipe, can be penetrated by microwaves and is used for loadingcoupling fluid, the arc-surface antenna array comprises a plurality of microwave antennas, and the microwave antennas are arrayed in an arc surface; the microwave signal processing unit comprises a microwave transmitting module and a microwave receiving module; each microwave antenna is connected with the microwave signal processing unit; and an opening at one end of the ventilation pipe is connected to the skull hood and communicates with an inner cavity of the skull hood, and the other end of the ventilation pipe is connected with the vacuum negative pressure generating module. According tothe multi-channel portable microwave scanning brain imaging device and the method disclosed by the invention, the ventilation pipe and the elastic loading module are arranged, so that the elastic loading module loaded with the coupling fluid can be tightly attached to the microwave antennas, a microwave signal is less influenced, and the imaging effect is good.

Description

technical field [0001] The invention relates to a microwave scanning imaging device and method, in particular to a portable multi-channel microwave scanning imaging device and method for the brain. Background technique [0002] Stroke is divided into hemorrhagic stroke and ischemic stroke, but the clinical treatment methods of the two types of stroke are mutually exclusive, so the diagnosis of stroke type before treatment is essential. According to European clinical guidelines, 4.5 hours after ischemic stroke is the golden period for thrombolytic therapy, and the earlier the better. However, due to transportation and other reasons, a large number of patients have missed the golden period of thrombolysis when they arrived at the hospital, so that less than 10% of ischemic stroke patients received thrombolysis. Therefore, it is of great significance to develop a portable, fast, and easy-to-operate instrument that can diagnose stroke types before hospitalization. [0003] At ...
