Abstract

The invention relates to a breast electrical impedance fault imager based on a mobile phone platform, belonging to the technical field of medical detecting instruments and biological detection. The fault imager comprises a breast detection component, an electrical impedance detection circuit and a mobile phone comprising data result display and analysis software, wherein the electrical impedance detection circuit comprises a singlechip, a frequency generator, a filtering amplifying circuit, an analog switch, an electrode group and an amplitude phase detection chip. The invention can make patients periodically checked and early diagnosed without going to hospitals and particular working environments by adopting a biological electrical impedance fault image detection technology and widely used mobile phones, and a personal medical record library can be saved so as to exchange with doctors in time and check patient's conditions. The imager has the characteristics of small volume, high safety, simple operation, low cost and the like and is especially suitable for household use.

Description

technical field [0001] The invention relates to electrical impedance tomography (EIT) equipment and measurement technology, in particular to mobile phone technology and USB2.0 communication technology, and belongs to the technical field of medical detection instruments and biological detection. Background technique [0002] According to the survey by the China Population Association, the incidence of breast cancer in my country has been increasing in recent years and has become one of the largest diseases among women. Breast cancer is one of the tumor diseases. Like other tumor diseases, the policy of early detection, early diagnosis and early treatment should be adopted for breast cancer. However, there are many disadvantages in the examination of breast cancer in our country at present, so that the incidence of breast cancer in women in our country has not improved. [0003] Breast cancer is one of the most common malignant tumors in women. Its incidence is on the rise gl...
