SYSTEM FOR DIAGNOSING BREAST CANCER USING X-RAY AND BREAST DENSITY MEASUREMENT METHOD

摘要

PURPOSE: A system for diagnosing a breast cancer using an x-ray and breast density measurement method therefor are provided to irradiate an ultrasonic wave to a fixed breast to calculate the propagation speed of the ultrasonic wave, thereby measuring the density of the breast. CONSTITUTION: A system for diagnosing a breast cancer using an x-ray comprises the following units. A breast fixing device(120) is made of an upper plate and a lower plate and fixes a breast. An ultrasonic wave sensor(130) detects an ultrasonic wave passing the breast and the upper plate. The ultrasonic wave sensor is installed on the upper plate of the breast fixing device. A control unit(150) determines the density of a breast by using the reciprocating time and distance of the ultrasonic wave. The upper plate is made of a material through which the ultrasonic wave passes. The lower plate is made of a material which reflects the ultrasonic wave.
