Description

Mammography device and method of photographing subject using same {MOMMOGRAPHY APPARATUS AND METHOD OF PHOTOGRAPHING OBJECT USING THE SAME}

The present invention relates to a mammography apparatus for X-ray imaging of a subject and a method of photographing a subject using the same, and more particularly, to eliminate or minimize pain or discomfort to a subject, thereby providing a comfort to the subject, while providing high photographing accuracy. The present invention relates to a mammography apparatus that can be achieved and a method for photographing a subject using the same.

The present invention is derived from the research conducted as part of the development of the nanomaterial-based multi-X source and tomographic image system technology of the Ministry of Knowledge Economy [Task control number: 10037414, Title: Nano-based multi-X source and tomography image system Technology development].

X-ray refers to electromagnetic waves having a short wavelength corresponding to a wavelength of 0.01 nm to 10 nm and a frequency of 30 × 10 ¹⁵ Hz to 30 × 10 ¹⁸ Hz. X-ray imaging is one of radiography that projects and displays the inside of a subject under the high penetrating power of the x-ray. As is well known, X-rays are accompanied by attenuation due to the material, density and thickness of an object, such as compton scattering and photoelectric effects during the transmission of the object. Accordingly, X-ray imaging projects and displays the inside of the subject on a plane based on the amount of attenuation of the accumulated X-ray during the process of passing through the subject.

In recent years, X-ray imaging technology has been combined with the semiconductor sector, and instead of the traditional analog method using film, digital X-ray imaging technology has various advantages such as relatively high resolution, wide dynamic range, easy generation of electrical signals, and simple data processing and storage. Is rapidly evolving. Digital-based imaging technology strongly reflects the clinical and environmental needs of early diagnosis of disease based on the excellent diagnostic capabilities of digital imaging.

Accordingly, by utilizing the inherent biological tissue contrast ability of X-rays, the internal structure of the breast as a subject is expressed in high resolution images, and the breast-only X-ray imaging which can detect lesions and microcalcifications for the detection and early diagnosis of breast cancer Technology "Digital Mammography" is introduced. Such digital mammography is rapidly spreading due to various advantages of digital x-ray imaging technology and the inherent characteristics of minimizing the exposure through image magnification, reducing the number of shots, increasing the resolution, and adjusting the brightness and contrast ratio.

The general mammography apparatus has a vertical columnar support column having a lower end fixed to the bottom, and a C-shaped or overall structure configured to be movable up and down in the vertical direction on the support column, and the middle part to be rotatable about a horizontal axis. C-arms or device bodies exhibiting similar shapes. A generator for irradiating X-rays toward the lower end is mounted at the upper end of the apparatus main body, and a detector facing the generator is mounted at the lower end of the apparatus main body. Between the generator and the detector is provided with a pressing pad for linearly reciprocating up and down along the inner surface of the apparatus main body.

In such a mammography apparatus, when the subject enters the sitting position or the sitting position in the photographing position, the apparatus main body is lifted and rotated with respect to the support column so that the height and the angle are adjusted so that the breast of the subject is placed at the desired position on the detector. The compression pad then compresses the breast by moving towards the detector. In this state, the generator irradiates the X-ray toward the breast and the detector, and the detector located behind the breast receives the X-ray passing through the breast to obtain an image.

That is, the detector generates an electric signal for each position in proportion to the incident amount of the X-ray. When the electric signal and the position information are read and processed by an image processing algorithm, the detector may obtain an X-ray image of the breast for the corresponding angle. Then, by repeating the above process while rotating the generator and the detector with the breast in between, the mammography apparatus can obtain a high-resolution image of the breast of the subject at various angles of the lateral oblique view (Mediolateral Oblique View).

In the general mammography apparatus having the above photographing principle, the key driving mechanisms for minimizing the inconvenience of the examinee and obtaining high quality X-ray images are the pressing operation of the compression pad and the lifting and rotating operation of the apparatus main body. In particular, the compression pad is directly connected to the pain and discomfort felt by the subject by applying pressure directly to the breast during X-ray imaging, and the device body is directly connected to the quality of the X-ray image as the correct body position is determined by lifting and rotating.

Here, the purpose of the compression pad to compress the breast is to take a picture in the state in which the breast is pressed in order to separate the cores (parts likely to have lesions or microcalcifications) and the like that overlap with the mammary gland.

However, the compression by the compression pad is a pain that the subject feels the most, and in particular, the degree of the pain is usually different depending on the bio-index of the subject. For example, the smaller the breast size, the higher the breast density, the younger the subject, the greater the pain.

Moreover, conventional mammography devices generally have a compression pressure of such a compression pad adjusted to a manual value, but the compression speed is generally constant. That is, in the conventional mammography apparatus, the compression pad is controlled by the uniform manual value irrespective of the biometric index of the subject, thereby failing to provide a photographing environment suitable for the subject, and the subject feels great pain and discomfort. Moreover, due to such pain and discomfort, when the subject moves, it is impossible to obtain an accurate X-ray image.

Accordingly, the present invention has been proposed to solve the above-mentioned problems, and the mammography apparatus and the same can be used to achieve high imaging accuracy while providing comfort to the subject by eliminating or minimizing the pain or discomfort to the subject. The object is to provide a method for photographing a subject.

The bioindex may include one or more selected from the group consisting of age, gender, height, weight, pregnancy, breast size, breast density, and body mass of the subject.

The bioindex determination unit may include a bioindex detection unit including at least one selected from the group consisting of a breast size measurer, a breast density measurer, and a body fat measurer.

The controller may move the compression pad to a condition selected from the group consisting of constant velocity, acceleration, deceleration, and combinations thereof.

According to another aspect of the present invention, there is provided a mammography apparatus including a generator for irradiating x-rays, a detector facing the generator, and a compression pad moving between the generator and the detector to press the subject; Determining a bioindex of the subject; And pressing the subject while controlling the moving distance and the speed of the compression pad based on the determined bioindex of the subject.

The pressing of the subject may include determining a moving distance and a speed of the pressing pad based on the determined bioindex of the subject; And moving the pressure pad at the determined distance and speed of movement of the pressure pad.

Determining the bio-index of the subject may include receiving data obtained from the bio-index detection unit including at least one selected from the group consisting of a breast size meter, a breast density meter, and a body fat analyzer.

The pressing of the subject may move the pressing pad to a condition selected from the group consisting of constant velocity, acceleration, deceleration, and a combination thereof.

By the mammography apparatus of the present invention and the subject photographing method using the same, it is possible to provide comfort to the subject by eliminating or minimizing the pain or discomfort applied to the subject. Furthermore, since X-ray imaging can be performed in such a comfortable state, high imaging accuracy can be achieved, thereby reducing exposure to X-rays by reducing the number of unnecessary shots.

1 is a perspective view showing the overall configuration of the mammography apparatus according to the present invention, Figure 2 is a perspective view showing a partial configuration including a drive unit and a controller of the pressure pad constituting the mammography apparatus according to the present invention.

As shown in FIG. 1, the mammography apparatus according to the present invention includes a device body 100 including basic components for X-ray imaging, and a support column 200 to which the device body 100 is vertically movable. Include. The support column 200 is a vertical columnar support having a lower end fixed to the bottom, and provides a vertical axis to the apparatus main body 100 so that the apparatus main body 100 can be elevated in a vertical longitudinal direction.

The device main body 100 is also called a C arm because the upper and lower ends face each other in an arc shape, and thus exhibit a C shape or similar shape as a whole. The apparatus body 100 includes a column connection 110 connected to the column 200 in a vertical direction and a vertical connection 120 rotatably connected to the column connection 110. The device main body 100 is mounted on one end (eg, the upper end in this embodiment) of the vertical connection part 120 of the device main body 100 to face the other end (for example, the lower end in this embodiment) that faces. A generator 130 for irradiating the X-ray toward the detector 130, a detector 140 mounted at the other end of the vertical connection part 120 to face the generator 130, and a generator 130 along the inner surface of the apparatus main body 100. And a compression pad 150 that linearly reciprocates between the detectors 140. The subject is positioned between the compression pad 150 and the detector 140 to perform X-ray imaging, but selectively installs the test plate 160 between the compression pad 150 and the detector 140 to press the subject. The X-ray imaging may be performed by being positioned between the pad 150 and the test plate 160.

The column connector 110 is connected to the vertical connector 120 so as to be rotatable about a horizontal axis so that the breast can be photographed by internal and external photographing, and a rotation driver (not shown) for rotating the vertical connector 120 in this way. It is installed.

As shown in FIG. 2, the vertical connection part 120 basically includes upper and lower ends at which the generator 130 and the detector 140 are mounted, and two pillars 121 connecting the upper and lower ends, respectively. The vertical connection part 120 includes a drive motor 122 provided at the upper end as a driving means for moving the pressing pad 150 up and down, a pulley 126 installed at the lower end, and a rotational axis and a vertical connection part of the drive motor 122. Drive belt 124 spanning pulley 126 at the lower end of 120. The two pads 121 of the vertical connection part 120 are slidably connected to the pressing pad support part 152 and one side of the driving belt 124 is fixedly connected to the pressing pad support part 152. By this structure, the drive belt 124 moves up and down as the drive motor 122 rotates, and the press pad support part 152 moves up and down accordingly. At this time, the pressing pad 150 is fixed to the front end of the pressing pad support 152, and the pressing pad 150 moves up and down together with the pressing pad support 152. This vertical movement of the compression pad 150 compresses the breast positioned on the detector 140 or, optionally, on the test plate 160.

The generator 130 mounted on the upper end of the apparatus main body 100 generates an x-ray by colliding electrons having high kinetic energy with a target of metal. Preferably, the generator 130 controls an irradiation direction or an irradiation area of the x-ray. Optical systems, such as a collimator, are provided.

The detector 140 mounted on the lower end of the apparatus main body 100 is basically a means for receiving an X-ray passing through the breast to obtain an image. The detector 140 may also serve as a support for supporting a body by placing the breast on it. . That is, the breast is pressed between the detector 140 and the compression pad 150 by pressing the breast with the compression pad 150 after placing the breast on the detector 140. The breast of the patient is photographed by the generator 130 and the detector 140. The detector 140 may generate an electrical signal for each position in proportion to the incident amount of the X-ray, and may read the electrical signal and the position information and process the same by an image processing algorithm to obtain an X-ray image of the breast. At this time, the detector 140 has a direct conversion method for obtaining an electrical signal directly from the X-ray without an intermediate step according to the conversion method of the X-ray, or indirect conversion for converting the X-ray into visible light to obtain an electrical signal indirectly by the visible light. General technical content such as method can be widely applied.

The test plate 160 may be included as an optional configuration in order to replace the function of the detector 140 as a test subject support. When the test plate 160 is included, the breast is pressed by the compression pad 150 and the test plate 160, and the breast in this state is photographed through the generator 130 and the detector 140. Therefore, the detector 140 performs only a function of receiving an X-ray passing through the breast to obtain an image.

In the mammography apparatus configured as described above, the driving motor 122 is driven by the controller 300 in order to press the breasts located on the detector 140 or, optionally, the test plate 160. The controller 300 is a component for controlling all components of the mammography apparatus, and functions other than the function of controlling the movement of the compression pad 150 are the same as those of the conventional mammography apparatus. That is, the function of controlling the movement of the compression pad 150 may be functionally added to the controller of the previously installed mammography apparatus. Alternatively, the controller 300 may be provided in the form of a sub-controller to control only the movement of the compression pad 150 and other components of the mammography apparatus may be controlled in a separate main controller. In this specification, only the function of controlling the movement of the pressing pad 150 of the controller will be described in any case.

As shown in FIG. 2, the controller 300 receives the bioindex from the bioindex input unit 410 and / or the bioindex detection unit 420 and drives the driving motor 122 based on the biometric index. The support 152 and the compression pads 150 connected thereto are moved up and down at a desired distance and speed to compress the breasts positioned on the detector 140 or, optionally, the test plate 160. For convenience, the bioindex input unit 410 and / or the bioindex detection unit 420 are referred to as a bioindex determination unit.

The controller 300, which is a main component of the present invention, will be described in detail with reference to FIGS. 2 and 3. 3 is a block diagram of a controller constituting a mammography apparatus according to the present invention.

As shown in Figures 2 and 3, the bioindex determination unit of the mammography apparatus according to the invention biometric index input unit 410 for inputting the biometric index of different subjects and / or biometric index for detecting the subject's bioindex The sensing unit 420 is included.

The bio-index input unit 410 is a unit for inputting the bio-index, for example, age, gender, height, weight, pregnancy status, etc. of the examinee identified from the outside of the mammography apparatus, into the mammography apparatus. It may include a connected keyboard, a touch panel of a monitor, a remote controller, and the like.

The bio-index detection unit 420 is a part for measuring the bio-index of the subject in the mammography apparatus, and includes a measuring instrument for measuring the size and / or density of the breast of the subject, a measuring instrument for measuring the body mass of the subject. The bioindex detection unit 420 may be installed on one side of the mammography apparatus, preferably one side of the apparatus main body 100.

Next, the configuration of the controller 300 to control the movement of the compression pad 150 by the value input by the bio-index input unit 410 and / or sensed and measured by the bio-index detection unit 420 And operation will be described with reference to FIG.

The controller 300 includes a compression speed controller 320 including a bioindex data receiver 322, a compression speed determiner 324, and a motor controller 326, and a compression speed database (DB) 340. do.

The biometric data receiver 322 of the compression speed controller 320 receives biometric data from the bioindex input unit 410 and / or the bioindex detection unit 420 and transmits the bioindex data to the compression speed determiner 324. . The compression speed determiner 324 communicates with the compression speed DB 340 to match the movement distance and the speed of the compression pad pre-stored in the compression speed DB 340 according to the bio-index data for the final movement of the compression pad 150. Determine distance and speed. The determined data about the final moving distance and the speed of the compression pad 150 is transmitted to the motor controller 326, and the motor controller 326 controls the operation of the driving motor 122 according to the received data. In this case, the compression speed DB 340 may store the movement distance and the speed of the compression pad for each bio-index in the form of a table, and may be mounted on a console fish connected to an internal / external memory or a mammography device in the controller 300. have.

Next, a method of x-ray imaging a breast of a subject using a mammography apparatus according to the present invention will be described with reference to FIG. 4. 4 is a flowchart illustrating a method of capturing a subject using a mammography apparatus according to the present invention. As shown in FIG. 4, the method of photographing a subject using a mammography apparatus according to the present invention is as follows.

The method includes the step of st1 positioning the subject to the photographing position of the mammography apparatus in a standing or sedentary state, and through the bioindex input unit 410 and / or the bioindex detection unit 420, Input and / or measuring (st2). These steps st1 and st2 may be reversed. For step st1, the apparatus main body 100 moves up and down along the column 200 to adjust the position of the detector 140 (or test plate 160 in some cases) to match the breast position of the subject. . This position adjustment is performed automatically or manually, and in order to be automatically performed, it is preferable to precede the step of measuring or inputting the breast position of the subject. In this case, while changing the order of steps st1 and st2, in step st2, data about the breast position of the examinee is added through the bioindex input unit 410 and / or the bioindex detection unit 420. Can be input and / or measured and automatically adjust the position of the detector 140 accordingly.

Subsequently, when the bio-index of the subject is input and / or measured, the controller 300 undergoes a step st3 of determining the moving distance and the speed of the compression pad 150. As described above, the bioindex data of the controller 300 is inputted and / or measured through the bioindex input unit 410 and / or the bioindex detection unit 420 in step st2. The receiving unit 322 receives, and the pressing speed determining unit 324 of the controller 300 communicates with the pressing speed DB 340 to determine the moving distance and the speed of the pressing pad 150 based on the received bioindex data. Decide

When the moving distance and the speed of the pressing pad 150 are determined in step st3, the motor controller 326 of the controller 300 drives the driving motor 122 to move the pressing pad 150 at the determined moving distance and the speed. Compression of the breast is performed by moving (step 4). When the compression is completed, the subject photographing method is ended through the step (st5) of x-ray imaging.

In such a subject photographing method, the correlation of the compression pad movement distance with time will be described with reference to FIGS. 5 to 9. 5 to 9 are graphs showing the correlation of the compression pad movement distance with respect to time in a subject photographing method using a mammography apparatus according to the present invention. In these graphs, the case where the breast size is the same, the case where the movement distance with respect to the time of the compression pad 150, ie, the distance which the compression pad 150 finally reaches by changing the compression speed, is made the same.

The movement distance change of the compression pad 150 with time may be largely divided into two groups and four cases. The first group (FIGS. 5 and 6) is a case in which the movement distance of the compression pad 150 is linear (case 1, C11 and C12) or nonlinear (case 2, C21 and C22) from the initial position to the completion of the compression. In the second group (FIGS. 7 and 8), the movement distance of the compression pad 150 may be defined by the first section Do to Dc from the initial position to the contact of the compression pad 150 with the breast and the compression pad 150 and the breast. Is divided into second sections Dc to Df from the contact of the contact to completion of the compression, linear in the first sections Do to Dc, and linear (case 3, C31 and C32) or in the second sections Dc to Df. This is the case for nonlinear (case 4, C41 and C42). On the other hand, the dotted line denoted by C0 in the graph of Figs. 5 to 9 is a case of the mammography apparatus according to the prior art, and shows the moving distance with time of the pressing pad moving at a fixed constant speed.

First, the graph shown in FIG. 5 is a case where the moving distance of the compression pad 150 increases linearly with time in the first group, that is, when the speed of the compression pad 150 is constant (cases 1, C11, and C12). . Compared to the case of the pressing pad moving at a fixed constant speed (C0) in the mammography apparatus according to the prior art, the mammography apparatus according to the present invention has a higher constant velocity (C11) or a lower constant velocity (C12) than the prior art. The pressing pad 150 may be moved. In the case of applying the compression at a high isochronous speed (C11), the compression of the breast is completed in a fast time (tf11), whereas in the case of applying the compression at the low isospeed (C12), the time for the compression of the breast is long (tf12) is long. Lose. The compression rate may be appropriately determined between C11 and C12 depending on the bioindex of the subject.

6 is a case in which the moving speed of the pressing pad 150 decreases or increases in the first group, that is, when the pressing pad 150 moves at deceleration or acceleration (cases 2, C21 and C22). The graph C21 shows a case where the pressing speed of the pressing pad 150 gradually decreases from the initial position to the completion of the pressing, and the graph C22 shows the pressing speed of the pressing pad 150 from the initial position to the pressing completion. It indicates an increase. This is the case where the pressure starts at a sudden compression and is gradually compressed at the time when the compression is completed (C21), and the pressure is suddenly applied at the time when the compression is started and the pressure is completed (C21). In accordance with this, the degree of change in the compression speed can be appropriately determined.

Next, in the second group, the graph shown in FIG. 7 moves at a constant speed up or down at a constant value until the compression is completed after the contact point tc of the compression pad 150 moves at a constant speed. This is the case (case 3, C31 and C32). The graph C31 illustrates a case in which the pressing speed of the pressing pad 150 is increased to a constant value after the contact, and the speed of the pressing pad 150 is increased from the first position to the contact position by the first speed in the sections Do to Dc. When divided by V1 and the second speed V2 of the sections Dc to Df from the contact position to the pressing-completed position, it has a relationship of V1 < V2. In addition, the graph C32 shows a case in which the pressing speed of the pressing pad 150 decreases to a constant value after contact, and the speed of the pressing pad 150 is reduced from the initial position to the contacting position in the intervals Do to Dc. When divided into the 1st speed V1 and the 2nd speed V2 of the sections Dc-Df from a contact position to a press completed position, it has a relationship of V1> V2.

In the graph shown in FIG. 8, the speed of the compression pad 150 gradually increases or decreases until the compression is completed after the time point tc in which the compression pad 150 moves at a constant speed in contact with the breast in the second group. While moving, with acceleration or deceleration (case 4, C41 and C42). The graph C41 illustrates a case in which the pressing speed of the pressing pad 150 gradually increases after the contact, and the speed of the pressing pad 150 is increased from the first speed (Do to Dc) from the initial position to the contact position. When divided by V1) and the second speed V2 of the sections Dc to Df from the contacting position to the pressing completion position, V1 is constant and V2 has an increase relationship. The graph C42 illustrates a case where the pressing speed of the pressing pad 150 gradually decreases after contact, and the speed of the pressing pad 150 is changed from the first position (Do to Dc) from the initial position to the contact position ( When divided by V1) and the second speed V2 of the sections Dc to Df from the contact position to the pressure-compressed position, V1 is constant and V2 has a decreasing relationship.

In addition to these four cases, as shown in FIG. 9, the compression speed may be increased or decreased after the time point tc in which the compression pad 150 moves at a constant speed and contacts the breast. In this case, if the breast is pressed while reducing the pressure applied to the breast, the overall pain may be reduced. This may be referred to as a combination of C41 and C42 in FIG. As such, the movement of the pressing pad 150 may be implemented in various forms in addition to those illustrated in FIGS. 5 to 9.

According to the mammography apparatus and the subject photographing method using the same according to the present invention, it is possible to provide comfort to the subject by providing high photographing accuracy and eliminating or minimizing pain or discomfort to the subject.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the spirit of the present invention. It will be apparent to those who have the knowledge of.
