To kill cancer cells without affecting normal tissues,it is very important to accurately control the temperature of the tissue,which directly affects the effectiveness of cancer hyperthermia.
40min is the usual dosage of o-ral squamous cell carcinoma local hyperthermia in clinic. At this heating dosage,heating not only doesn't promote the ex-pression of UPA mR NA of human tongue squamous cell carcinoma cells(Tca8113),but also inhibits it.
The tissue temperature detection in hyperthermia has a big affection to therapy effect,and noninvasive tissue temperature estimation can be realized using ultrasound.
Thus, knowledge of the blood perfusion distribution is necessary in order to optimize cancer hyperthermia treatments.

One hundred and five patients of nasopharyngeal carcinoma with large metastatic cervical lymphnodes were divided randomly into three groups, 35 for each group. Group A, treated by'combined therapy of Shenlong liquid with thermo-and radio-therapy, group B with combined therapy of thermo-and radiotherapy and group C with radiotherapy alone. The clinical conditions of the three groups were similar before treatment. At the end of treatment, the immediate regression rate of cervical lymphnodes of A, B, C group w...
Ultrasound hyperthermia system is a kind of medical device to restrain and kill tumor.As its intelligent component, the master computer control subsystem is in charging of the automatic operation of the whole system. This paper discusses thoroughly about the implementation of main functions of this master computer software, including the adaptive PID temperature control,communication protocol, interface, archives management and etc.Great emphasis is put on how to apply the object oriented metheod and event...
A heat transfer model is presented for the hyperthermia treatment of cervix cancer using an intracavitary microwave applicator. The specific absorbtion rate (SAR)distributed for the transvaginal probe is measured in a phantom. On this basis, the 3-D finite element simulation of the temperature field is conducted. And the results figured out through programming are compared with that from commercial software called ANSYS. Besides in terms of clinical practice the variations of the parameters are studied,invo...
