Description

[0001] APPARATUS FOR ACQUIRING IMAGE OF A BREAST CANCER DIAGNOSING [0002]

The present invention relates to an image capturing apparatus for breast cancer diagnosis, and more particularly, to an image capturing apparatus for breast cancer diagnosis for diagnosing a breast cancer lesion occurring inside the 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, an image acquisition device for breast cancer diagnosis using mammography, which is mainly used for breast cancer diagnosis of asymptomatic women among breast cancer diagnosis methods, is to detect lesions existing in the breast by using x-rays.

However, the conventional image acquisition apparatus for breast cancer has a problem in that it is difficult to detect a mass of breast, which is an important factor in the diagnosis of breast cancer, since the result of imaging using X-ray is a two-dimensional image.

The conventional two-dimensional image generated through the image acquisition device for breast cancer diagnosis has a problem in that the accuracy and the discrimination power are 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.

As described above, the conventional image acquisition apparatus for breast cancer diagnosis is low in accuracy of diagnosis, so that even if there is breast cancer, breast cancer which is read normally or positively can be mistaken for breast cancer, And it is becoming a main cause of 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.

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 the state that the diagnosis object B is pressed and fixed in different states by the compression paddle 430, the X-ray transmission image obtained by examining the diagnosis object B and the diagnostic object 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 the diagnosis object B is lesioned and generating diagnostic data by matching and comparing the X-ray transmission image and the light transmission image are complicated have.

However, the image acquisition device 1 for diagnosing breast cancer according to an embodiment of the present invention is configured such that the diagnosis object B is compressed and fixed, and the same kind of image is obtained through the X-ray diagnosis unit 200 and the optical diagnosis unit 300 The X-ray transmission image and the light transmission image having the position, the state, and the angle can be obtained, so that the diagnosis data for determining whether the diagnosis object B is lesion can be easily obtained. That is, since the diagnostic data for the diagnosis object B can be generated without matching the X-ray transmission image and the light transmission image with each other, there is a characteristic effect that the diagnostic data of the diagnosis object B can be generated quickly and accurately do.

The image acquiring device 1 for diagnosing breast cancer is configured such that the subject is placed between the X-ray diagnosis unit 200 and the optical diagnosis unit 300 in a state where the subject B is disposed between the compression paddles 430 Inspect the diagnostic object (B). At this time, the diagnosis object is inspected for the diagnosis object B while holding the handle 120 formed on the body 100 to prevent the diagnosis object B fixed to the compression paddle 430 from flowing . At this time, since the horizontal transfer unit or the vertical transfer unit is disposed at a lower portion of the diagnosis object B and operates, it does not invade the area where the body of the diagnosis object is disposed.
