Abnormal cell detecting device

A method for detecting an abnormal cell, comprising the steps of:

• attaching at least a pair of electrodes to a portion of a body to be measured, at least one electrode of this pair being formed of electrode cells;
• supplying each of said electrode cells with first and second voltages having different frequencies between said electrodes;
• independently detecting from between each electrode cell of one electrode and the other electrode of said electrode pair, first and second impedance values obtained from the body portion being measured when the first and second voltages are supplied across said electrodes;
• calculating a plurality of ratios by dividing the first and second impedance values obtained from each cell by said detecting step;
• and
• deciding the presence or absence of abnormal cells in the body portion based on the calculated plurality of ratios,
• said frequencies of the first and second voltages being selected so as to border the range of dispersion of frequency-specific inductive cacacity of the cells of said body portion, whereby a difference between the electrostatic capacitances measured at the body portion at the two frequencies is made great.

A method for detecting abnormal cells at a body portion to be examined, comprising the steps of:

• attaching first and second electrodes to a portion of a body to be examined, at least said first electrode being formed of a plurality of electrode cells;
• supplying between each of said electrode cells of said first electrode and said second electrode, first and second voltage signals having different frequencies, said different frequencies being selected so as to border the range of dispersion of frequency-specific inductive cacacity of the cells of said body portion, whereby the difference between the electrostatic capacitances measured at the body portion at the two frequencies is great;
• independently detecting, from between each electrode cell of one electrode and the other electrode of said electrode pair, first and second impedance values obtained from the body portion being examined when the first and second voltage signals are supplied across said electrodes;
• calculating a plurality of ratios by dividing the first and second impedance values obtained from each electrode cell during said detecting step;
• storing in a memory section of a memory means at a predetermined address the ratio calculated for each of said electrode during said calculating step;
• processing data by selecting the address of said memory means at which an abnormal data representing an abnormal cell is stored, so that an image data corresponding to said given data is outputted;
• and
• displaying said image data in the form of various visual images,
• said data processing steps including the steps of storing in a first memory section of said memory means the results of said calculating step, computing and storing in a second memory section of said memory means a normalized value based on the contents of said first memory section, computing and storing in a third memory section of said memory means data designating the location of the maximum values of the contents of said first memory section, and computing and storing in a fourth memory section of said memory means abnormal value data designating the position of any abnormal cells in said body portion being examined based on the contents of said first memory section.
