Abstract

The invention discloses a thermoacoustic imaging system for lymphedema imaging as well as a control method thereof, and belongs to field of medical treatment. The thermoacoustic imaging system for lymphedema imaging comprises a pulsed microwave source, an ultrasonic transducer, a thermoacoustic signal processing unit, a data acquisition unit and a computer, wherein the pulsed microwave source is used for exciting thermoacoustic effect in a lymphedema region to generate a thermoacoustic signal; the ultrasonic transducer is used for receiving the thermoacoustic signal; the thermoacoustic signalprocessing unit comprises an amplifier and a filter which are correspondingly used for amplifying and filtering the thermoacoustic signal; the data acquisition unit is used for performing A / D conversion on the amplified and filtered thermoacoustic signal to acquire a digitized thermoacoustic signal; the computer is used for controlling the pulsed microwave source, performing image reconstruction on the digitized thermoacoustic signal to acquire an thermoacoustic image and performing color coding on the thermoacoustic image to realize the prominent imaging of lymphedema.

Description

technical field [0001] The invention relates to the medical field, in particular to a thermoacoustic imaging system for lymphedema imaging and a control method thereof. Background technique [0002] Lymphedema refers to tissue swelling caused by lymphatic reflux disorder, mainly lymphatic vessel obstruction and dysplasia. It often occurs in the calf, upper arm, genitals, and face. The clinical manifestations of lymphedema: in the early stage, when pressing with fingers, there will be obvious sunken indentation, and in the late stage, the skin and subcutaneous tissue will proliferate, the skin wrinkles will deepen, and the skin will become thick and hard. , looks like elephant skin. Swelling may disappear or lessen with early elevation of the affected area or with bed rest. In the late stage, the swelling of the affected limb is obvious, the surface keratosis is rough, and it is rubbery. A few may have skin cracks, ulcers or verrucous growths. [0003] Regarding the measu...
