[0001] Apparatus and method for measuring urinary bladder [0002]

The present invention relates to an apparatus and method for measuring intra-bladder metastasis, and more particularly, to a method and apparatus for measuring an intra-bladder metastasis in a non-invasive manner using ultrasound, The present invention relates to an apparatus and method for measuring a urinary bladder in a urinary bladder, which enables a user to easily and precisely measure a urine volume in a bladder.

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. Korean Registered Utility Model No. 20-137995 discloses a "portable ultrasonic diagnostic apparatus ".

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.

In this way, ultrasonic diagnostic equipment is used to measure the amount of urine in the bladder, and two methods are widely used. The first method calculates the amount of urine from the vertical and horizontal plane images of the bladder obtained using general ultrasonic diagnostic equipment. Although many algorithms have been proposed and used, this method shows not only a significant error rate but also different results depending on the user There is a problem that it is expressed. The second method uses a dedicated ultrasonic device for measuring the amount of urine, and US Pat. No. 4,926,871 and US Pat. No. 6,884,217 disclose dedicated ultrasonic devices. However, most of the dedicated ultrasound equipment according to the second method uses the information about the bladder extracted from two ultrasonic signals of the vertical plane and the horizontal plane of the bladder, and calculates the quantity of the bladder. There is a difficulty.

Therefore, Applicant can visually confirm the direction of the direction of the transducer in the direction of the center of the bladder in the B-mode ultrasound image, thereby quickly and precisely grasping the position of the bladder, thereby quickly and accurately calculating the amount of bladder .

FIG. 4 is a flowchart sequentially illustrating the operation of the control unit in the apparatus for measuring intra-bladder mobility according to a preferred embodiment of the present invention. Referring to FIG. 4, when the bladder position determination mode is selected (step 410), the controller 100 repeatedly displays the ultrasound images in the direction of the transducer at predetermined time intervals, (Step 420) and measure and provide the urinary bladder at the location. The user selects the bladder position determination mode using the switch unit after closely positioning the transducer at an arbitrary position on the abdomen of the patient and selects the position of the bladder in the ultrasound image output to the display unit while slowly changing the direction of the transducer . When the center point of the bladder is positioned at a desired position or the center point of the bladder coincides with the center line of the ultrasound image in the bladder positioning mode, the user fixes the transducer at the corresponding position and selects the measurement mode of the bladder, . This allows the transducer to perform an ultrasound scan to measure the intra-bladder weights at a location that precisely directs the center of the bladder, allowing accurate measurement of the bladder mass.

Hereinafter, the operation of the control unit in the bladder position confirmation mode in the apparatus for measuring intra-bladder disease according to the present invention will be described in detail.

If the bladder position determining mode is selected, the central control unit repeats a series of operations until the weighing mode is selected, and displays the center point of the bladder on the fan-shaped ultrasound image on the display unit. 5 (a) and 5 (b) are images exemplarily shown on the display unit by the execution of the bladder positioning mode in the apparatus for measuring intra-bladder mobility according to a preferred embodiment of the present invention. Referring to FIG. 5, a '+' mark is displayed at the center point of the bladder in the ultrasound image.

 In the bladder position confirming mode, the above-described series of operations is repeatedly performed at regular intervals until the weighing mode is selected, and the image of the corresponding plane is output to the display unit. The repetition period is preferably about 5 seconds or less. Accordingly, when the user changes the position and the direction of the transducer positioned on the abdomen of the patient, the position of the ultrasound image and the bladder displayed on the display unit also changes.

The series of operations repeated in the bladder position confirming mode includes: (1) performing a prescan operation to acquire ultrasonic signals for a plurality of scan lines constituting a single scan plane using a transducer (step 412) (2) generating and displaying an ultrasound image for a single plane using the ultrasound signals acquired by the pre-scan operation (step 414); (3) using the ultrasound signals acquired for the scan plane to generate position information (Step 416), (4) detecting the center point of the bladder using the extracted position information of the bladder (step 418), (5) displaying the center point of the bladder in the displayed ultrasound image 419 to visually inform the center of the bladder in the ultrasound image.

The pre-scan operation (step 412) of the series of operations (step 412) includes sequentially moving the second stepper motor along a single scan surface in the direction in which the transducer arranged close to the abdomen of the patient is oriented, And acquires ultrasound signals for a plurality of scan lines by scanning.

In order to obtain ultrasonic signals constituting a single scan plane in the pre-scan operation (step 412), the control unit transmits a drive control signal for sequentially rotating the second step motor by predetermined angles to the drive control unit, The drive control unit rotates the second step motor in the yz direction (i.e., the second direction) in accordance with the drive control signal from the central control unit. The transducer is also rotated together with the rotation of the second step motor. The transducer obtains ultrasound signals for n scan lines in the yz direction by rotating at predetermined angles along the yz direction. On the other hand, the central control unit receives ultrasonic signals of n scan lines in the yz direction from the transducer, processes the received ultrasonic signals, and acquires a two-dimensional ultrasonic image for the scan surface.

FIG. 6 illustrates an example of a device for measuring intra-bladder mobility according to a preferred embodiment of the present invention, in which a center line of an ultrasound image and a center point of a bladder are displayed together. 6, when the center line of the ultrasound image and the center point of the bladder coincide with each other, the user can visually recognize that the direction of the transducer is correct and the bladder is located at the center of the ultrasound image do.

(4) a method for detecting the center point of the bladder (step 418) among the above series of operations will be exemplified. FIG. 7 is a view for explaining a process of finding a center point of a bladder in an apparatus for measuring a urinary bladder according to a preferred embodiment of the present invention. Referring to FIG. 7, first, position information corresponding to front and rear walls of the bladder are detected from a plurality of ultrasonic scan lines constituting a scan plane obtained by the pre-scan operation. (A, B, C, and D) of the bladder among the position information on the front wall and the rear wall of the bladder are extracted, and the position information (a _y + b _y ) / 2 of the y-axis direction position information (a _y , b _y ) and an intermediate value of the position information (c _x , d _x ) in the _x- may be set to _{((c x + d x)} / 2) made of a coordinate, that is, _{((c x + d x)} / 2, (a y + b y) / 2) the center of the bladder.

In the bladder positioning mode, the control unit may display a center point of the bladder using one of a cross mark, an arrow, and an arbitrary shape graphic at a central point of the bladder in the displayed ultrasound image. Meanwhile, the control unit calculates the cross-sectional area of the bladder, and the size of the mark displayed at the central point can be determined in proportion to the cross-sectional area of the bladder. That is, the size of the mark may be set in advance so as to be proportional to the cross-sectional area of the bladder and stored in the database, and the size of the mark corresponding to the cross-sectional area of the bladder measured may be read from the database and determined. When the cross-sectional area of the bladder is small, the size of the mark is small as shown in Fig. 5 (a), and when the cross-sectional area of the bladder is large, the size of the mark can be displayed as shown in Fig. 5 (b). Thus, by changing the size of the mark in proportion to the size of the bladder, the user can visually recognize the size of the bladder through the size of the mark relative to the center point.

When the nurse measuring mode is inputted in the bladder position checking mode, the central control unit performs (1) a scan operation to acquire ultrasonic signals for a plurality of scan planes using a transducer (step 422), (2) ) Estimating the volume of the bladder using the ultrasound signals acquired by the scanning operation (step 424), and (3) measuring and providing the urine volume corresponding to the estimated volume of the bladder (step 426).

Hereinafter, the scan operation in the yaw rate measurement mode will be described in detail. As the central control unit 100 rotates the first step motor and the second step motor, the transducer acquires ultrasound signals of n scan lines for each of the m scan planes. The process of acquiring ultrasound signals of n scan lines on the m scan planes of the transducer is as follows. First, the first step motor is fixed, and then the second step motor is sequentially rotated by a predetermined angle, and ultrasound signals of one scanning line are acquired at a position where the transducer is moved, and acquires ultrasound signals of n scan lines.

Next, the first stepping motor moving in a direction orthogonal to the second stepping motor is sequentially rotated at a predetermined angle m times, and at the corresponding position, the above-described process (i.e., obtaining the ultrasonic signals constituting one scan plane To obtain ultrasound signals constituting m scan planes. Therefore, a three-dimensional image is generated using two-dimensional images obtained for m planes. At this time, it is preferable that the number m of the acquired two-dimensional images is at least 4 but not more than 30. As described above, by the rotation movement of the first step motor and the second step motor, the ultrasonic wave is diverged and received as a conical shape having the transducer as a vertex as a whole, and the cubic volume of the bladder can be measured.

Hereinafter, a specific procedure for obtaining the volume of the bladder using the acquired ultrasound signals for a plurality of scan planes obtained by the scan operation in the weft mode will be described. However, a method of obtaining the volume of the bladder using the acquired ultrasound signals on a plurality of scan planes may be variously suggested, and the method proposed herein is merely an example.

The position of the front wall of the bladder and the positions of the back wall of the bladder for each scanning line are detected from the ultrasound information of each scanning line constituting one side, [1], Depth [2], ..., Depth [n]. Then, the area (Area) of the corresponding surface is obtained by summing the difference values for the scanning lines constituting each surface.

In this way, the process of obtaining the area of the surface is repeated for m planes to obtain the areas (Area [1], Area [2], ..., Area [m]) of each surface. In this case, various methods of obtaining the area of each surface by using the difference value between the front wall position and the back wall position of the bladder of each scanning line can be presented in various ways. One of them is to use the rotational movement angle of the second step motor And the area of the surface is calculated by summing up the area of each area from the sector shape of one scanning line and the area of the entire line having the wall. The other is to repeatedly perform the process of obtaining an area of a trapezoidal shape composed of two front walls and two back walls of two adjacent scanning lines for all the scanning lines and to calculate the total area by summing the trapezoidal areas thus obtained.

If the first axis of rotation is to be scanned at a position deviated from the center of the bladder, a smaller amount than the actual bladder is calculated so that the actual amount and error . In order to attenuate these errors and to accurately measure the urine in the bladder, numerical correction is performed. Hereinafter, a process of numerical correction will be described.

First, difference values between the front wall position and the back wall position of the bladder with respect to the n scan lines constituting each surface are obtained. Next, the maximum difference values BladderDepth [1], BladderDepth [2], ..., BladderDepth [m] of each of the difference values are obtained (step 426), and the maximum values BladderDepth [ 1], BladderDepth [2], ..., BladderDepth [m]).

Next, using the total maximum value MaxBladderDepth and the maximum difference values BladderDepth [1], BladderDepth [2], ..., BladderDepth [m] on each surface, correction coefficients for each surface ComFactor (1), ComFactor [2], ..., comFactor [i], ComFactor [m]

Next, assuming that the image of the bladder of each surface is a circle, a circle having the same area as the areas (Area [1], Area [2], ..., Area [m] The radiuses (r [1], r [2], ..., r [i], r [m]) are determined and determined as the radius for the bladder image on each side.

Next, the correction radii (ComR [1], ComR [2], ..., ComR [i], ComR [m]) for the correction coefficient and the radius of the bladder image of each surface are obtained by the equation (2).

The average radius (AverageR), which is the average value of the calculated correction radius for each side of the bladder image, is obtained. Next, the total volume (V) of the urine in the bladder is calculated using the average radius according to Equation (3), assuming that the entire bladder is a sphere.

Through the above-described process, the ultrasonic diagnostic apparatus for bladder diagnosis according to the present invention can accurately detect the urine volume (V) in the bladder.

In addition, the ultrasonic diagnostic apparatus for bladder diagnosis according to the present invention can extract information on the bladder such as the thickness of the bladder and the weight of the bladder as well as the residual amount in the bladder from the two-dimensional images, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood that various changes and modifications may be made without departing from the spirit and scope of the invention.
