<p>An ultrasonic diagnosis apparatus for diagnosing a bladder and a diagnosing method thereof are provided to acquire ultrasonic information for a three-dimensional image with the small size and weight by including two step motors having two rotation axes and at least one transducer. An ultrasonic diagnosis apparatus for diagnosing a bladder includes a transducer(110), a transducer supporting bar, an analog signal processing unit(150), a display unit(170), a central control unit(100), a first step motor(120), a second step motor(130), and a driving control unit(140). The transducer(110) radiates an ultrasonic signal for one scan line, and receives the ultrasonic signal reflected from an object. The transducer supporting bar fixes the transducer(110). The analog signal processing unit(150) converts the ultrasonic signal transmitted from the transducer(110) into a digital signal. The display unit(170) outputs a predetermined image signal. A central control unit(100) processes an image based on the digital ultrasonic signal transmitted from the analog signal processing unit(150). The central control unit(100) outputs the processed image to the display unit(170), and controls a whole operation. The first step motor(120) rotates along a first direction. The second step motor(130) rotates along a second direction. The driving control unit(140) controls operations of the first step motor(120) and the second step motor(130) according to a driving control signal of the central control unit(100). The transducer supporting bar is rotated along the first direction by rotation of the first step motor(120). The transducer supporting bar is rotated along the second direction by rotation of the second step motor(120). The central control unit(100) calculates a urine quantity of the bladder based on ultrasonic information for n scan lines of m planes which are sequentially received from the analog signal processing unit(150).</p> |
