[0029] figure 1 It is a schematic diagram of the microwave thermoacoustic early liver cancer imaging detection device of the present invention, including a microwave trigger 1-1, a microwave generator 1-2, a transmitting antenna 1-3, an ultrasonic transducer 1-5, and a data acquisition card 1 connected in sequence -6 and computer 1-7, the microwave generator is triggered by the microwave trigger, and transmits pulsed microwaves to the liver of the human body to be measured through the transmitting antenna, and uses the thermoacoustic effect to excite and generate ultrasonic signals; the ultrasonic transducer converts the ultrasonic signals After being converted into an electrical signal, it is transmitted to the data acquisition card, and finally input to the computer, and the image is reconstructed by using the filter back projection algorithm and ultrasonic processing technology. In this embodiment, the pulse sequence of the microwave trigger is triggered by a computer. The...
