Description

[0002] Diagnosing apparatus for breast lesion [0003]

The present invention relates to a device for diagnosing a breast lesion, and more particularly, to a device for diagnosing a breast lesion that occurs in the inside of a breast.

With the advent of the age of aging and the improvement of people's standard of living, there is a growing interest in the early diagnosis and treatment of illness in order to lead a healthy life. In the case of cancer among various diseases, As the most important factor that threatens the public health.

According to the Cancer Registration Division of the Ministry of Health, Welfare and Family Affairs, it is estimated that more than 130,000 new cancer patients occur annually in Korea. Using the number of cancer cases registered between 2003 and 2005, 300.0 cases of women and 248.2 cases of women.

The incidence of cancer is higher in the order of stomach cancer, lung cancer, liver cancer, and colon cancer, which account for 66% of the total male cancer incidence, while cancer incidence is higher in breast cancer, thyroid cancer, Stomach cancer, colon cancer, and lung cancer, breast cancer is higher than the four major cancer.

Thus, early diagnosis and treatment of breast cancer, which has the highest incidence rate in women, is an important factor that must be preceded for the healthy living of women.

On the other hand, among the breast cancer diagnosis methods, mammography diagnostic apparatus using mammography, which is mainly used for breast cancer diagnosis in asymptomatic women, is to detect lesions existing in the breast by using X-rays.

However, in the conventional apparatus for diagnosing breast lesion, since the result of imaging using X-ray is a two-dimensional image, the lesion of the region of interest overlaps with the normal tissue, so that it is difficult to detect a mass of breast which is an important factor in the diagnosis of breast cancer.

Such a two-dimensional image generated through the conventional apparatus for diagnosing a breast lesion has a problem that the accuracy and discrimination power thereof is low and diagnosis of erroneous breast cancer is high.

Specifically, the x-ray absorptivity of breast tissue and cancer is very difficult to distinguish because of the small difference between them, and thus there is a high probability of false positive or false negative. In reality, 30% of false positive diagnoses are in the medical diagnosis field.

Such conventional diagnostic apparatus for breast lesion has a low diagnostic accuracy as described above. Even if there is breast cancer, normal or positive mammograms, which are read as positive, overlook the breast cancer, And it is becoming a main cause of causing legal problems due to medical accidents while threatening the health of patients.

Therefore, it is urgently required to develop a breast cancer diagnosis method with high accuracy so as to reduce the probability of false positives and false negatives in the diagnosis of breast cancer so that unnecessary re-imaging and biopsy are not required.

1 to 12, a breast lesion diagnosis apparatus 1 according to an embodiment of the present invention includes a main body 100, an x-ray diagnosis unit 200, an optical diagnosis unit 300, and a transfer unit 400 do.

The body 100 may include a support member 110 coupled to the conveyance unit 400 and supporting the ground so that the body 100 can be stably erected. The body 100 may be rotatably coupled to the transfer unit 400.

The X-ray diagnosis unit 200 can generate an X-ray diagnosis image of the diagnosis object B. The x-ray diagnosis unit 200 may be installed in the transfer unit 400. The X-ray diagnosis unit 200 may include an X-ray irradiation unit 210 and an X-ray detection unit 220.

The X-ray irradiating unit 210 can generate an X-ray and irradiate the X-ray to the diagnosis target B. Here, the X-ray irradiating unit 210 may be an X-ray tube. The X-ray irradiating unit 210 may be installed on the transfer unit 400. In other words, the X-ray irradiating unit 210 may be installed in the transfer unit 400 so as to be disposed above the diagnosis object B. The X-ray irradiating unit 210 intermittently or continuously rotates according to a predetermined angle range (for example, from -21 degrees to 21 degrees) by the transfer unit 400 and irradiates the X- have. For example, the X-ray irradiating unit 210 may be intermittently rotated about the diagnosis object B. More specifically, the X-ray irradiating unit 210 can be rotated and rotated about a predetermined angle. At this time, the X-ray irradiating unit 210 can irradiate the X-ray toward the diagnosis object B when it is rotated after being rotated by a predetermined angle. Alternatively, the X-ray irradiating unit 210 may irradiate the X-ray toward the diagnostic object B when the X-ray irradiating unit 210 rotates by the set range and reaches the set angle.

The X-ray detecting unit 220 may be arranged to face the X-ray irradiating unit 210. For example, the X-ray detection unit 220 may be installed in the transfer unit 400 to be disposed below the diagnosis object B. The x-ray detector 220 can acquire an x-ray diagnostic image of the diagnosis object B from the x-ray transmitted from the x-ray irradiator 210 and transmitted through the diagnosis object B. The x-ray detector 220 can convert the x-ray diagnostic images of the diagnosis object B into 3d data based on the x-rays irradiated from the x-ray irradiator 210 toward the diagnosis object B at various angles.

Meanwhile, the x-ray detector 220 may be a digital semiconductor flat panel detector. In the semiconductor flat plate detector, a plurality of sensors are configured in a matrix form. Such a semiconductor flat panel detector can have advantages such as high resolution, wide dynamic range, high electrical signal generation, and easy data processing as compared with a conventional film.

Accordingly, not only real-time processing and reproduction of the X-ray diagnosis image can be performed, but also a high-resolution X-ray diagnosis image can be obtained even with a relatively small amount of X-ray.

The X-ray irradiating unit 210, the X-ray detecting unit 220, and the diagnostic object B may be arranged in a straight line. Thus, the focus of the X-ray irradiated from the X-ray irradiating unit 210 can be coincident with the diagnosis object B, and thus it is possible to acquire a high-quality X-ray diagnostic image without error with respect to the diagnosis object B. Here, it is preferable that the diagnosis target B is disposed between the X-ray irradiating unit 210 and the X-ray detecting unit 220.

The optical diagnosis unit 300 can generate an optical diagnostic image of the diagnosis object B. The optical diagnosis unit 300 may include a light irradiation unit 310 and a light detection unit 320.

The light irradiation unit 310 may be formed of a plurality of light sources 311 arranged to have a predetermined pattern. The light irradiation unit 310 may be installed on the transfer unit 400. In other words, the light irradiation unit 310 may be installed in the transfer unit 400 so as to be disposed above the diagnosis object B. Alternatively, the light irradiation unit 310 may be installed below the transfer unit 400 so as to be disposed below the diagnosis object B.

The light detecting unit 320 may be arranged to face the light irradiating unit 310. For example, the photodetector 320 may be installed in the transfer unit 400 such that the photodetector 320 is positioned on the opposite side of the light irradiating unit 310 with respect to the diagnosis target B. The photodetector 320 can acquire the photodiagnosis image of the diagnosis object B from the light irradiated from the light irradiation unit 310 and transmitted through the diagnosis object B. For example, the photodetector 320 may be formed of a plurality of photodiodes 321 arranged to have a predetermined pattern. The plurality of photodiodes 321 disposed in the photodetector 320 may be disposed at positions corresponding to the plurality of light sources 311 disposed in the light irradiating unit 310. Here, the photodiode 321 may be an APD (Avalanche Photo Diode).

The photodiagnosis unit 300 can detect the photodiagnosis images of the diagnosis object B through the light source 311 having the predetermined pattern of the light irradiation unit 310 and the photodiode 321 of the light detection unit 320 Can be acquired and 3d data can be obtained.

For example, the first driving member 413 may be a combination of a motor for generating power through electricity and a means for transmitting power to the second rotating shaft 422. For example, the first driving member 413 may be disposed inside the main body 100 and coupled to the first rotating shaft 412 through a gear, a belt, a chain, or the like. Alternatively, the first driving member 413 may be directly connected to the first rotating shaft 412 without a means for transmitting power.

The second transfer unit 420 is disposed adjacent to the diagnosis object B. For example, the second transfer unit 420 may be coupled to the main body 100 and a part of the second transfer unit 420 may be positioned below the diagnosis object B. The second transfer unit 420 may rotate the third transfer unit 430 with respect to the object B to be diagnosed.

For this, the first transfer unit 410 may include a second base 421, a second rotation shaft 422, and a second drive member 423.

The second base 421 is coupled to the second rotation axis 422 and may be disposed to protrude upward and downward with respect to the second rotation axis 422 by a predetermined length. The second base 421 may rotate along the second rotation axis 422. The third transfer unit 430 and the pressing pockets 440 may be disposed on the second base 421. For example, the pressing paddle 440 may be disposed on the upper portion of the second base 421, and the third conveying unit 430 may be disposed on the lower portion of the pressing paddle 440. As will be described later, the third base unit 421 can be coupled to the third transfer unit 430 and the compression paddle 440 in a liftable manner.

One side of the second rotation shaft 422 is coupled to the second base 421 and the other side is coupled to the main body 100. For example, the second rotation axis 422 may be rotatably coupled to the front surface of the main body 100. Specifically, the second rotation shaft 422 may be formed in a shaft shape and may be rotatably coupled to the main body 100 through a bearing. The second rotation shaft 422 may rotate the first base 411 through the power provided by the second driving member 423.

For example, the second rotation axis 422 may be inserted into the first rotation axis 412 and the first rotation axis 412 may be inserted into the second rotation axis 422 . Although not shown, the first rotation shaft 412 and the second rotation shaft 422 are coupled by a bearing and can rotate in the same direction or in different directions.

The second driving member 423 may be coupled to the second rotating shaft 422 and may be coupled to provide power to the second rotating shaft 422. For example, the second driving member 423 may be a combination of a motor and a means for transmitting power to the second rotation shaft 422. For example, the second driving member 423 may be disposed inside the main body 100 and coupled to the second rotating shaft 422 through power transmission means such as a gear, a belt, and a chain. Or the second driving member 423 may be directly connected to the second rotation shaft 422 without the power transmitting means.

10 to 12 are front views illustrating an operation state of a breast lesion diagnosis apparatus according to an embodiment of the present invention. FIG. 13 is a flowchart illustrating an operation of examining a diagnosis target through a breast lesion diagnosis apparatus according to an embodiment of the present invention FIG.

The operation and effect of the apparatus for diagnosing a breast lesion according to an embodiment of the present invention will be described with reference to FIGS. 10 to 13. FIG.

First, in order to examine the diagnostic object B using the breast lesion diagnostic apparatus 1, the diagnostic object B is first placed between the compression paddles 440. At this time, the subject to be diagnosed (B) may be a breast.

The sixth drive member 443 is activated to place one of the upper plate 441 or the lower plate 442 when the diagnostic object B is positioned between the upper plate 441 and the lower plate 442 of the compression paddle 440. [ To the diagnosis object B side. For convenience of explanation, it is assumed that the upper plate 441 is lifted or lowered by the sixth driving member 443.

The upper plate 441 is lowered by the sixth driving member 443 and is brought into contact with the upper portion of the diagnosis object B and presses it with a constant pressure. At this time, the pressure at which the upper plate 441 presses the diagnostic object B according to the size or state of the diagnostic object B can be adjusted.

The third transfer unit 430 moves the X-ray detecting unit 220 to closely contact the lower portion of the diagnosis target B and then the X-ray diagnosis unit (not shown) 200). &Lt; / RTI > At this time, the X-ray irradiating unit 210 is in a state of being aligned with the diagnosis target B.

More specifically, the horizontal transfer unit 432 operates to move the X-ray detecting unit 220 disposed on the horizontal transfer member 432a to be disposed below the diagnosis object B. In general, when the X-ray diagnosis is performed first, the initial setting can be performed with the X-ray detector 220 being disposed below the diagnostic object B. When the placement of the X-ray detecting unit 220 is completed, the first vertical transferring unit 431 raises the horizontal transferring member 432a to position the X-ray detecting unit 220 close to the lower portion of the diagnosis target B.

When the process is completed, the X-ray irradiating unit 210 irradiates the X-ray toward the diagnosis target B, and the X-ray detecting unit 220 irradiates the X-ray irradiating unit 210 with the X- And generates an image.

Next, the X-ray irradiating unit 210 rotates the X-ray irradiating unit 210 by a predetermined angle with respect to the first rotation axis 412 and irradiates the X-ray to the diagnosis target B. Specifically, the first base 411 rotates about the first rotary shaft 412 and rotates the X-ray irradiating unit 210. More specifically, when the first driving member 413 provides power to the first rotating shaft 412, the first base 411 coupled to the first rotating shaft 412 and the first rotating shaft 412 rotates, The X-ray irradiating unit 210 disposed on the upper portion of the first base 411 also rotates. At this time, the first driving member 413 can control the power provided to the first rotary shaft 412 so that the X-ray irradiating unit 210 is continuously or intermittently rotated by a predetermined angle.

On the other hand, when the x-ray diagnosis unit 200 completes the inspection of the diagnosis object B and acquires the x-ray diagnosis image, the optical diagnosis unit 300 proceeds to the inspection of obtaining the optical diagnosis image of the diagnosis object B. At this time, the diagnosis target B is in a state of being fixed by the pressing paddle 440.

First, the first vertical transfer unit 431 moves the X-ray detecting unit 220 downward. When the lowering of the X-ray detecting unit 220 is completed, the horizontal transferring unit 432 moves the light irradiating unit 310 and the photodetecting unit 320 to be disposed at the upper and lower portions of the diagnosis target B, respectively.

Specifically, the first vertical conveying member 431a moves down the horizontal conveying member 432a along the first moving path 431b by the power provided by the third driving member 431c. The horizontal conveying member 432a is moved along the second moving path 432b by the power provided by the fourth driving member 432c and the optical detecting unit 320 is moved to the diagnosis target (B). At this time, the second vertical transfer unit 433 is coupled to the first vertical transfer unit 431a, and the light irradiation unit 310 is coupled to the second vertical transfer unit 433 at positions corresponding to the photodetector unit 320, And moves along the horizontal transfer member 432a toward the diagnosis object B together. The light irradiating unit 310 is disposed on the third base 433a and is moved toward the diagnosis target B along the horizontal transfer member 432a so as to be disposed above the diagnosis target B.

The first vertical transfer part 431 and the second vertical transfer part 433 then move the photodetector part 320 and the light irradiation part 310 up or down to be disposed adjacent to the diagnosis object B.

Specifically, the first vertical transfer unit 431 raises the horizontal transfer member 432a to position the photodetection unit 320 close to the lower portion of the diagnosis target B. In other words, the first vertical transfer unit 431 raises the horizontal transfer member 432a to bring the photodetection unit 320 into close contact with the lower plate 442 pressing the diagnosis object B. The second vertical transfer unit 433 moves the second vertical transfer member 433b to lower the light irradiating unit 310 to the upper portion of the diagnosis object B. In other words, the second vertical transferring part 433 moves down the second vertical transferring part 433b to bring the light irradiating part 310 into close contact with the upper plate 441 pressing the diagnosis object B.

When the light detecting unit 320 and the light irradiating unit 310 are arranged so as to be in close contact with the diagnosis target B, the optical diagnosis unit 300 inspects the diagnosis target B.

More specifically, the light irradiation unit 310 irradiates light toward the object B to be diagnosed. At this time, the light irradiated from the light irradiation unit 310 toward the diagnosis object B may be infrared rays.

Then, the light transmitted through the diagnostic object B is provided to the optical detector 320, and the optical detector 320 acquires the optical diagnostic image of the diagnostic object B through the provided light.

The X-ray diagnosis unit 200 and the optical diagnosis unit 300 may be configured to scan the diagnosis target B in a state in which the X-ray diagnosis unit 200 and the optical diagnosis unit 300 are rotated by a predetermined angle with respect to the first rotation axis 412 and the second rotation axis 422, can do.

The third transfer unit 430 coupled to the second transfer unit 420 rotates together with the rotation of the first transfer unit 410 and the second transfer unit 420 so that the first transfer unit And the optical diagnosis unit 300 and the compression paddle 440 coupled to the second transfer unit 420 and the third transfer unit 430 are rotated by a predetermined angle. At this time, the first transfer unit 410 and the second transfer unit 420 rotate in opposite directions to each other by a predetermined angle. For example, when the first conveying unit 410 rotates counterclockwise by 20 degrees, the second conveying unit 420 rotates clockwise by 20 degrees. Thus, the first transfer unit 410 and the second transfer unit 420 can maintain an initial state in which they are aligned with each other.

In this state, the diagnostic object B is placed between the compression paddles 440 and fixed while being pressed, and the X-ray diagnosis unit 200 and the optical diagnosis unit 300 sequentially detect the diagnosis object B To obtain x-ray diagnostic images and optical diagnostic images.

As described above, the apparatus for diagnosing the breast lesion 1 according to the embodiment of the present invention can perform the X-ray diagnosis and the optical diagnosis in a state in which the diagnosis target B is pressed and fixed through the compression paddle 440 The inspection time can be drastically reduced, and accordingly, the diagnostic target (B) that can be inspected in one day can be greatly increased, which can increase the profit of the hospital.

Conventionally, when the inspection through the X-ray is completed, the inspection is carried out by moving the optical fiber. At this time, since the diagnosis object B is inspected in a state in which the object B is pressed and fixed in different states by the compression paddle 440, the diagnosis object (B) B, < / RTI > different shapes, positions, states, and angles. This poses a problem that it is difficult to generate diagnostic data for determining whether or not the diagnosis object B is lesioned. That is, a series of processes for generating a three-dimensional image through image information for determining whether or not a lesion of the diagnosis object B is lesioned and generating diagnosis data by matching the x-ray diagnosis image and the photodiagnostic image to each other is very complicated have.

However, the apparatus for diagnosing a breast lesion 1 according to an embodiment of the present invention is configured such that the diagnosis target B is compressed and fixed, and the same shape, position, and position are determined through the X-ray diagnosis unit 200 and the optical diagnosis unit 300, The X-ray diagnosis image and the photodiagnostic image having the state and angle can be obtained, so that diagnostic data for judging the lesion of the diagnosis object B can be easily obtained. That is, the diagnostic data for the diagnosis object B can be generated without matching the X-ray diagnosis image and the optical diagnosis image with each other, so that the characteristic effect that the diagnosis data of the diagnosis object B can be generated quickly and accurately is generated do.
