example 1

[0121] The operation steps of this example can be roughly divided into: initialization, scanning positioning, heating scheme determination, microwave emission parameter determination, microwave emission, temperature monitoring and judgment, hyperthermia / non-hyperthermia time judgment and control, end and other steps.

[0122] In the following, the operation example 1 of the phased array microwave energy transmission device 10 of the present invention will be described by taking the phased array microwave energy transmission device 10 of the present invention for scanning, positioning and heating a specific target of a living body as an example.

[0123] Such as Figure 6 As shown, first, in the initialization step S11: the phased array microwave energy transmission device 10 of the present invention starts to operate, and the scanning positioning unit 12 first refers to other detection equipment, such as the preliminary detection of B-ultrasound machine, X-ray machine, nuclear ...

example 2

[0131] The difference between the operation example 2 of the phased array microwave energy transmission device 10 of the present invention and the above-mentioned example 1 is only that: between steps S12 and S13, a resonance frequency determination step S25 is added (see Figure 7 ), wherein the control unit 11 controls the microwave energy transmission control unit 13 and the temperature measurement unit 14 to jointly determine the resonance frequency of the specific target.

[0132] In the resonant frequency determination step S19, the microwave energy transmission control unit 13 controls the energy transmission microwave source 162 to generate a series of low-power microwaves with continuously increasing frequency in the preset frequency band, and transmit the microwaves through the phased array antenna unit 17 to At the precise spatial position of the specific target determined by the scanning positioning unit 12 in step S12. At the same time, the temperature measurement...

example 3

[0135] In each of the above examples, the main purpose of the hyperthermia and inactivation of biological tissues is to operate. However, there may be safety concerns when performing hyperthermia on biological tissues at some special locations (for example, lesion tissues near complex vascular structures). In this case, the non-thermal effect of microwaves on organisms can be used to irradiate the biological tissue with microwaves to produce non-thermal effects (such as cell membrane perforation, easy drug introduction, cutting DNA, etc.).

[0136] Such as Figure 8 As shown, in this example, the judgment of non-thermal treatment mode is added. For example, in the treatment plan determination step S13: the control unit 11 further determines whether to adopt a thermal therapy mode or a non-thermal therapy mode, and determines the power, waveform, frequency and pulse mode of the non-thermal therapy microwave used in the non-thermal therapy mode. .

[0137] If the control unit...
