Abstract

The invention provides a multi-frequency holographic microwave brain imaging system and an imaging method. The imaging method comprises the following steps: transmitting ultra-wide band microwave signals to an object in an area to be detected by using a transceiver-integrated microwave antenna, detecting scattered electric field signals of the object in the area to be detected, and processing thescattered electric field signals of the object in the area to be detected to obtain two-dimensional reconstructed images of the objects in the area to be detected; presetting an electromagnetic numerical model of the head according to the total visible scattered electric field of all microwave antennas, and obtaining a two-dimensional reconstructed image of the head according to the electromagnetic numerical model of the head; judging whether the two-dimensional reconstructed image of the head and the two-dimensional reconstructed image of the object in the area to be detected are the same, determining that the object in the area to be detected is a head organ if the two-dimensional reconstructed image of the head and the two-dimensional reconstructed image of the object in the area to bedetected are the same, and transmitting the two-dimensional reconstructed image of the head to an image display module for display. The method of the invention is non-contact and non-invasive, can continuously monitor diseases such as cerebral apoplexy, and has high resolution of reconstructed brain images.

Description

technical field [0001] The application belongs to the technical field of microwave imaging, and in particular relates to a multi-frequency holographic microwave brain imaging system and imaging method. Background technique [0002] Stroke seriously endangers the health of middle-aged and elderly people in my country, affects the quality of life, brings a heavy economic burden to the patient's family and brings a heavy medical burden to the society. Early detection, early diagnosis and early intervention are the key to achieving timely rescue and treatment of stroke. Medical imaging technologies such as X-ray computed tomography, computerized tomography (CT), magnetic resonance imaging (MRI), and ultrasound imaging are currently common medical imaging diagnostic technologies for stroke. However, X-ray computed tomography and CT will produce ionizing radiation that is harmful to human health, and cannot realize continuous and real-time monitoring of the development of cerebra...
