Abstract:
1. A method for selecting and separating a normal cell and a cancer or tumor cell by using an ultrasonic wave, the method comprising: (a) individually radiating the ultrasonic wave to each of a plurality of sample cells that are obtained from tissue of a portion of a mammal including humans; (b) measuring an attenuation coefficient, a speed of sound, or the attenuation coefficient and speed of sound on the basis of the sample cells to which the ultrasonic wave is radiated; (c) classifying a group A of sample cells in which the measured values of the attenuation coefficient, speed of sound, or attenuation coefficient and speed of sound are smaller than an average value with respect to total samples as normal cells, and a group B of sample cells in which the measured values of the attenuation coefficient, speed of sound, or attenuation coefficient and speed of sound are higher than the average value with respect to the total samples as cancer or tumor cells; and selecting and separating each individual sample cell that has a measurement value corresponding to an average±standard deviation of the measurement values with respect to the group A and samples that have measurement values corresponding to the average±standard deviation of the measurement values in group B to group A or group B respectively.
