[0001] Stand-alone type ultrasonic scanner [0002]

The present invention relates to an ultrasonic scanner, and more particularly, to an ultrasonic scanner having an ultrasonic sensor module and an operation recognition sensor module capable of sensing the direction of the ultrasonic sensor module and the scan position information, A plurality of one-dimensional ultrasound data, and a plurality of sets of probing data including directional direction information / scan position information of the ultrasound sensor module that has acquired each one-dimensional ultrasound data, And more particularly, to a stand-alone ultrasonic scanner and a stand-alone bladder ultrasonic scanner which approximate information and provide information.

Generally, an ultrasonic system emits an ultrasonic signal to an object to be inspected by a piezoelectric effect of a transducer as a transducer, and as a result, receives an ultrasonic signal reflected from a discontinuous surface of an object and returns, And outputs the image data to a predetermined image device to inspect the internal state of the object. Such an ultrasonic wave system is widely used for medical diagnosis, nondestructive inspection, underwater search instruments, and the like.

However, most of the conventional ultrasonic diagnostic apparatuses have a disadvantage that their volume and weight are so large that their movement is not easy. To solve this inconvenience, various suggestions for a portable ultrasonic diagnostic device have been proposed.

On the other hand, it has been used as an indispensable factor to measure the urine volume in the urinary bladder in the examination of the bladder abnormality or the urination disorder. In addition, in order to prevent the abnormalities that may be caused after the operation, the urine volume in the bladder may be measured prior to urination using the catheter, and the urine volume in the bladder may be used as a guideline in the urination training.

Thus, the ultrasonic diagnostic apparatus for measuring the urine volume in the bladder obtains a 2-dimensional ultrasound image of a scan face of a fan shape including a bladder, obtains a cross-sectional area or radius of the bladder from a 2-dimensional ultrasound image, And the urine volume in the bladder is calculated. In order to improve the accuracy of measurement, other types of ultrasound diagnostic apparatuses are used to acquire 2D ultrasound images of a scan-type scan surface including a bladder in a plurality of directions, and to acquire 3D ultrasound images using a plurality of ultrasound images And calculate the urine volume in the bladder by estimating the volume of the bladder.

However, in order to obtain a two-dimensional ultrasound image of a scan surface of a fan shape, the conventional ultrasound diagnostic apparatus or the ultrasound-based bladder ultrasound scanner may include a plurality of ultrasonic sensors in an array form, And motors for rotating and moving the motor. That is, a plurality of ultrasonic sensors are spaced apart at predetermined intervals and sequentially acquire one-dimensional ultrasonic data from the respective ultrasonic sensors, or sequentially move and rotate the ultrasonic sensors by predetermined intervals using a motor, . In order to obtain a three-dimensional ultrasound image, a three-dimensional stereoscopic ultrasound image is obtained by sequentially acquiring and combining two-dimensional ultrasound images while moving the ultrasound sensors by a predetermined distance using a motor.

Korean Patent Laid-Open Publication No. 10-2012-0125578 discloses an ultrasonic imaging probe having a plurality of transducers and a motor. 1 is a perspective view showing an example of an ultrasound imaging probe equipped with a plurality of transducers and a motor disclosed in the above-mentioned Korean Patent Laid-Open Publication. As shown in FIG. 1, when a plurality of transducers are mounted, the size of the ultrasonic probe must be long along the longitudinal direction, and it must be included as a motor and a motor driving module. In addition, since the motor and the drive modules for driving the motor are vulnerable to shock and the like, there is a disadvantage that the equipment including the motor is poor in durability.

In addition, US Patent Publication No. US 2010/0204581 discloses a system and method for long-term volume determination using three-dimensional ultrasonic waves. FIG. 2 is a structural diagram for explaining a process of obtaining a two-dimensional ultrasonic image and a three-dimensional ultrasonic three-dimensional image by the ultrasonic scanner disclosed in the above-mentioned patent. 2, the ultrasonic scanner mechanically moves the transducer mechanically by a predetermined angle using a motor connected to the transducer, and acquires a plurality of one-dimensional ultrasonic data to generate a sector-shaped two-dimensional ultrasonic wave Image. Also, as shown in FIG. 2, the ultrasonic scanner rotates the transducers in the direction of the angle? By using a motor, and acquires a plurality of two-dimensional ultrasonic images to produce a three-dimensional stereo ultrasound image.

As described above, the conventional devices include a plurality of ultrasonic sensors in an array form to obtain two-dimensional or three-dimensional ultrasonic images, motors for rotating the ultrasonic sensors along the scan plane, and motor drive modules for driving the motors There is a disadvantage that the structure is complicated and the overall size becomes large.
