Abstract

The invention relates to a negative pressure type breast tissue dielectric parameter detecting device and a control method thereof. The detecting device comprises a radio frequency signal transmittingand receiving device, a micro controller, a getter device, a radio frequency switch array and a radio frequency connector arranged outside a flexible assembly and at least one coaxial probe embeddedin the flexible assembly. The getter device is connected to the microcontroller, the microcontroller is connected to the radio frequency switch array, the radio frequency connector is respectively connected to the radio frequency switch array and the coaxial probe, and the radio frequency switch array is connected to the radio frequency signal transmitting and receiving device. The flexible assembly is used for wrapping the measured breast tissue and form a confined space with the measured breast tissue. The microcontroller controls the getter device and controls the radio frequency switch array, and the coaxial probe detects the dielectric parameters of the measured mammary. The detecting device has the advantages of being capable of measuring the dielectric parameters in different areasof the measured breast tissue through one step by making the coaxial probe cling to the surface of the measured breast tissue, convenient to operate and capable of saving time.

Description

technical field [0001] The invention relates to the technical field of medical monitoring equipment, in particular to a negative-pressure breast tissue dielectric parameter detection device and a control method thereof. Background technique [0002] For the diagnosis of breast tumors, the existing diagnostic techniques include pathological diagnosis methods and imaging diagnosis methods. The pathological diagnosis method must make pathological slices from the human tissue parts to be examined, and in vivo measurement cannot be realized, which has this disadvantage. Imaging diagnostic methods mainly include mammography, color Doppler ultrasound, magnetic resonance imaging (MRI), positron emission tomography / computed tomography (PET / CT), but there are time or Space limitations, slow imaging speed, and some inspection methods have defects such as carcinogenicity caused by radioactive radiation, and low specificity and sensitivity of inspection. [0003] In response to these d...
