Description

[0001] APPARATUS AND METHOD FOR DIAGNOSING LUNG CANCER USING PULSE WAVE [0002]

TECHNICAL FIELD The present disclosure relates to an apparatus and method for diagnosing lung cancer.

In general, cancer is a disease in which early detection is difficult and treatment is difficult when the detection is late. Recently, the incidence of cancer has been steadily increasing, and several methods for diagnosing it have been proposed.

Non-invasive medical diagnostic techniques for cancer diagnosis include X-ray diagnosis and CT (Computed Tomography) diagnostic techniques.

In the diagnosis method using X-ray, the X-ray light source and the photosensitive plate are disposed, the patient is positioned therebetween, and the image of the internal organs of the human body is obtained by using the difference of the transmission power of X-ray. When the above method is used, a three-dimensional image of the inside of the human body is two-dimensionally expressed on a film.

In the diagnostic method using CT, as in the above method, the difference in the transmission power of the X-ray is used. In the diagnostic technique using CT, an X-ray source and detector are placed and the patient is positioned therebetween. Then, by detecting the intensity of the X-ray and the attenuation constant, the image processing by the computer is performed to reconstruct the image of the human body cross-section. In the diagnosis method using CT, the human body is scanned in the key direction to obtain many tomographic images, which is disadvantageous in that the patient is exposed to more radiation than general X-ray.

In particular, when the transmission module 100 is to be connected to an external device wirelessly, the transmission module 100 may be in the form of a capsule. According to the capsule shape, the examinee can take the transmission module 100 into the oral cavity.

The external device 300 can control the transmission module 100. Particularly, the pulse width of the pulse generated by the transmission module 100 can be adjusted through the external device 300. In addition, the position of the transmission module 100 can be adjusted through the external device. The transmission module 100 may move in a vertical direction along a human digestive organs (esophagus). The transmitting module 100 may generate a pulse wave while transmitting in a vertical direction along a human digestive organs (esophagus), and transmit the pulse wave to the receiving module 200.

The receiving module 200 may measure time delay information, size information, and phase information of the received pulse wave. In addition, the time delay information, size information, and phase information of the pulse wave can be confirmed by a user through a monitor of the external device 300 or the like.

In order to receive the pulse wave generated by the transmission module 100, the reception module 200 may be located at the upper half of the human body. In addition, the receiving module 200 may be positioned in contact with the surface of the human body or positioned close to the human body. Particularly, in order to diagnose lung cancer, the receiving module 200 can be distributed more widely than the area surrounding the lungs of the human body. The lung cancer diagnosis apparatus can diagnose lung cancer based on size information and phase information of a frequency domain signal corresponding to the pulse wave acquired by the reception module 200.

2 is a block diagram showing a lung cancer diagnosis apparatus using a pulsed wave according to an embodiment of the present invention.

As shown in FIG. 2, the lung cancer diagnosis apparatus may include a transmission module 100 for generating pulses and a reception module 200 for diagnosing (detecting) lung cancer based on the pulse wave. For example, the apparatus for diagnosing lung cancer using pulsed waves according to the embodiment of the present invention comprises: a transmitting module 100 for generating pulses; At least one receiving unit 202 for receiving a pulse wave generated by the transmitting module 100; A first detection unit (203) for detecting time delay information of the received pulse wave; A second detection unit (204) for detecting amplitude and phase information of a frequency domain signal corresponding to the received pulse wave; And a controller 205 for diagnosing lung cancer based on the time delay information, the amplitude and the phase information.

The second detection unit 204 converts a time domain signal of the received pulse wave into a frequency domain signal by applying an FFT (fast Fourier transform) operation to the received pulse wave, and outputs the amplitude and phase information of the frequency domain signal .

The apparatus for diagnosing lung cancer using pulse waves according to an embodiment of the present invention may further include a storage unit for storing the time delay information, amplitude and phase information and the like.

The control unit 205 generates a first lung cancer diagnosis result by diagnosing the lung cancer based on the time delay information, and diagnoses the lung cancer based on the amplitude and phase information, thereby generating a second lung cancer diagnosis result.

The control unit 205 may compare the first and second lung cancer diagnosis results with each other and output the comparison result to the output unit 208. [

The control unit 205 outputs the first or second lung cancer diagnosis result to the output unit 208 or outputs a comparison result of the first and second lung cancer diagnosis results to the output unit 208 208 in accordance with an instruction from the user.

3 is a flowchart illustrating a lung cancer testing method using a pulsed wave according to an embodiment of the present invention.

First, the communication unit 101 of the transmission module 100 transmits / receives information on the operation of the lung cancer diagnostic apparatus to the communication unit 206 and the external device 300 of the reception module 200. The control unit 102 of the transmission module 100 controls the overall operation of the transmission module 100.

The pulse wave generation unit 103 of the transmission module 100 generates a pulse wave based on the control signal of the control unit 102 and transmits the generated pulse wave to the reception module 200 To the wide-band reception antenna 201 (S11).

The pulse wave receiving unit 202 of the receiving module 200 receives the pulse wave transmitted from the transmitting module 100 through the wideband receiving antenna 201 and propagating through the human body, (203) and the magnitude and phase detector 204 (S12). The received pulse wave may be in a state in which its characteristics have been converted by a difference in electric characteristics such as lung and cancer.

The time delay detector 203 detects time delay information of the received pulse wave and outputs the time delay information of the detected pulse wave to the controller 205 (S13).

The control unit 205 controls the overall operation of the reception module 200 and generates a first lung cancer diagnosis result by diagnosing lung cancer based on the detected time delay information (S14). For example, the delay time of the pulse wave varies depending on whether the pulse wave passes through the lung (background medium) or through the arm (target), and based on the delay time (time delay information) Is determined.

The magnitude and phase measurement unit 204 converts the time domain signal of the received pulse wave into a frequency domain signal by applying an FFT (fast Fourier transform) operation to the received pulse wave at step S15.

The magnitude and phase measurement unit 204 detects magnitude and phase information of the frequency domain signal (S16), and outputs the magnitude and phase information of the detected frequency domain signal to the control unit 205. [

The control unit 205 controls the overall operation of the reception module 200 and determines the presence or absence of lung cancer and the size of lung cancer based on the detected size and phase information of the frequency domain signal to generate a second lung cancer diagnosis result S17).

The pulse wave can reach the receiving module 200 passing through the lung (background medium), arm (target) and located at the measuring point. At this time, due to scattering characteristics of the pulse wave, the magnitude and phase of the pulse wave may vary. That is, the characteristic of the received pulse wave is determined according to whether the pulse wave passes through the lung (background medium) or through the arm (target).

On the other hand, a unique phenomenon can be observed in the magnitude and phase of the frequency domain signal corresponding to the received pulse wave according to the shape and size of the scattering-type lung cancer, and the frequency relation of the pulsed wave applied. That is, in the presence of lung cancer, a double dip or double null can be identified. In addition, when lung cancer is present, a phase jump can be confirmed. The phase jump is a phenomenon in which a large phase difference occurs at a specific point.

Therefore, when the transmitting module 100 moving in the vertical direction along the human digestive organs (esophagus) generates and transmits a pulse wave and the receiving module 200 receives the pulse wave generated in the transmitting module 100, The control unit 205 can diagnose lung cancer by checking the characteristics of the received pulse wave.

The control unit 205 compares the first lung cancer diagnosis result and the second lung cancer diagnosis result with each other and determines whether the first lung cancer diagnosis result and the second lung cancer diagnosis result are identical to each other (S18). For example, the control unit 205 determines whether the first and second lung cancer diagnosis results are both a lung cancer determination, or whether the first or second lung cancer diagnosis result is not a lung cancer judgment.

The control unit 205 outputs the first lung cancer diagnosis result and / or the second lung cancer diagnosis result to the output unit 208 according to the user's selection signal, or outputs the first and second lung cancer diagnosis results to the output unit 208, 2 lung cancer diagnosis result is output to the output unit 208. [

The output unit 208 displays a comparison result of the first lung cancer diagnosis result and / or the second lung cancer diagnosis result or the first and second lung cancer diagnosis results performed by the control unit 205, (Time domain, frequency domain, multiple domain (time domain and frequency domain)) can be selected according to an instruction of the control section 205 (S19).

The communication unit 206 of the receiving module 200 transmits and receives information on the operation of the lung cancer diagnostic apparatus and the communication unit 101 and the external device 300 of the transmission module 100.

The storage unit 207 of the reception module 200 stores the received pulse wave, time delay information, size and phase information of a frequency domain signal, lung cancer diagnosis results of the control unit 205, and the like. The storage unit 207 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory 2 such as SD or XD memory, A random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM) , A magnetic disk, or an optical disk. The lung cancer diagnostic apparatus may operate in association with a web storage that performs a storage function of the storage unit 207 on the Internet.

The output unit 208 may be a display unit, and the display unit may display a lung cancer diagnosis result. For example, the display unit may display the detected time delay information, the magnitude and phase information of the frequency domain signal, the lung cancer diagnosis result, and the like.

The display unit may include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, And may include at least one of a 3D display, a plasma display panel (PDP), and a multi display tube (MDT).

As described above, the apparatus and method for diagnosing pulmonary cancer using pulse waves according to the embodiment of the present invention apply a fast Fourier transform (FFT) operation to a received pulsed wave, And the frequency domain is reconstructed from the frequency domain electromagnetic wave signal to detect lung cancer based on the detected time domain and frequency domain to improve the accuracy and reliability of lung cancer diagnosis results. And an apparatus and method for diagnosing lung cancer using the same.

The apparatus and method for diagnosing lung cancer using the pulsed wave according to the embodiment of the present invention are capable of simultaneously performing time domain and frequency region lung inspection and use a pulsed wave transmitting / receiving method, The hardware and circuit configuration have a simple effect. For example, a lung cancer diagnosis method using a continuous wave takes a long time because a frequency sweep is required in a wide frequency band where analysis is required, and the transmission / reception circuit and related hardware configurations are complicated. However, The apparatus and method for diagnosing lung cancer using pulsed waves according to the examples require only a pulsed wave having a broadband pulse width. Therefore, since the transmission / reception module and its hardware configuration are relatively simple, the size of the transmission / reception module can be reduced.

Since the apparatus and method for diagnosing pulmonary cancer using pulsed waves according to the embodiment of the present invention can obtain both the frequency domain lung cancer diagnosis result and the time domain lung cancer diagnosis result simultaneously, Reliability may be improved. For example, lung cancer diagnosis results can be obtained in multiple areas, and the time required for the lung cancer diagnosis test can be reduced, and the pain and discomfort felt by the patient during the lung cancer diagnosis test can be reduced.
