Description

[Technical Field]

[0001] The present disclosure relates to an ultrasonic irradiation device and an irradiation method thereof. [Background technology]

[0002] The most representative use of ultrasound in the medical field is an ultrasound imaging device that utilizes the transmission and reflection properties of ultrasound. For example, there is a device that obtains cross-sectional images of the inside of the human body by visualizing the time and intensity of reflection as ultrasound passes through each organ in the human body.

[0003] There are also devices that use the heat generated by High Intensity Focused Ultrasound (HIFU) to burn and remove tumors inside the human body, or induce the degeneration and regeneration of human tissue, resulting in skin cosmetic or skin shaping effects such as wrinkle reduction.

[0004] However, conventional high-intensity focused ultrasound irradiation devices had difficulty in accurately irradiating specific areas of the body without damaging normal tissue inside the body, resulting in low accuracy of ultrasound irradiation.

[0005] Furthermore, conventional ultrasound irradiation devices require doctors to carefully irradiate ultrasound, which limits the amount of time that can be shortened and the maximization of the effect of ultrasound irradiation. [Prior art documents] [Patent documents]

[0016] Furthermore, the processor may be characterized in that it determines at least one of an acquisition position and an acquisition angle of the acquisition unit for acquiring the cavitation information according to the position of the transmission signal of the ultrasound irradiation unit.

[0017] Furthermore, when the transmission path of the ultrasound irradiation unit changes, the processor may be characterized by controlling at least one of the acquisition position and acquisition angle of the acquisition unit so as to acquire cavitation information based on the cavitation channel already set in conjunction with the changed transmission path.

[0018] Furthermore, the processor may be characterized by controlling the ultrasonic irradiation unit so as to apply ultrasonic energy with a time delay that has already been set for each position of the transmission signal of the ultrasonic irradiation unit.

[0019] The processor may also be characterized by controlling the ultrasound irradiation unit to apply ultrasound energy at at least one of a pre-set irradiation time and intensity in conjunction with the position of the transmission signal of the ultrasound irradiation unit and a focal point for each irradiation site.

[0020] Furthermore, an ultrasound irradiation method performed by an ultrasound irradiation device according to another aspect of the present disclosure may include the steps of irradiating ultrasound to a human body using an ultrasound irradiation unit of the ultrasound irradiation device, acquiring cavitation information within the human body using an acquisition unit of the ultrasound irradiation device, and controlling the processor of the ultrasound irradiation device to apply ultrasound energy that has already been set in conjunction with a focal point for each irradiation area on the human body, or not to apply ultrasound energy, based on the cavitation information.

[0035] In this specification, the control unit of the ultrasound irradiation device according to the present disclosure includes various devices capable of performing arithmetic processing and providing a result to a user. For example, the control unit of the ultrasound irradiation device according to the present disclosure may include all or any one of a computer, a server device, and a portable terminal.

[0036] Here, the computer may include, for example, at least one of a notebook computer, a desktop computer, a laptop computer, a tablet PC, and a slate PC equipped with a web browser.

[0037] The server device is a server that communicates with external devices and processes information, and may include at least one of an application server, a computing server, a database server, a file server, a mail server, a proxy server, and a web server.

[0038] The portable terminal is, for example, a wireless communication device that ensures portability and mobility, and may include any kind of handheld-based wireless communication device such as at least one of a Personal Communication System (PCS), a Global System for Mobile communications (GSM), a Personal Digital Cellular (PDC), a Personal Handyphone System (PHS), a Personal Digital Assistant (PDA), an International Mobile Telecommunication (IMT)-2000, a Code Division Multiple Access (CDMA)-2000, a W-Code Division Multiple Access (W-CDMA), a Wireless Broadband Internet (WiBro) terminal, and a smartphone, as well as a wearable device such as at least one of a watch, a ring, a bracelet, an anklet, a necklace, glasses, contact lenses, or a head-mounted device (HMD).

[0039] The ultrasound irradiation device according to the present disclosure can control the ultrasound irradiation unit based on the acquired cavitation information within the human body so that the ultrasound irradiation unit applies the pre-set ultrasound energy in conjunction with the focal point for each irradiation area, or does not apply ultrasound energy.

[0040] The ultrasound irradiation device according to the present disclosure can accurately irradiate ultrasound to specific irradiation sites without damaging normal tissues in the human body, thereby improving the accuracy of ultrasound irradiation. Furthermore, the ultrasound irradiation device according to the present disclosure can adjust and irradiate ultrasound under optimal conditions for each irradiation site, thereby maximizing the effect of ultrasound irradiation while shortening the irradiation time.

[0041] The ultrasonic irradiation device will be described in detail below.

[0042] Fig. 1 is a diagram showing the configuration of an ultrasonic irradiation device according to the present disclosure, Fig. 2 is a diagram showing an example of a process in which the ultrasonic irradiation unit of Fig. 1 irradiates ultrasonic waves.

[0043] FIG. 3 is a diagram showing an example of a transducer of the ultrasonic wave irradiation unit of FIG.

[0044] Referring to FIGS. 1 to 3, an ultrasound irradiation device 100 may include an ultrasound irradiation unit 110, an acquisition unit 120, and a control unit .

[0045] The ultrasound irradiation unit 110 can irradiate ultrasound waves to the human body S according to the ultrasound focusing depth. Here, the ultrasound irradiation unit 110 can include a transducer array 111 having a variety of shapes. For example, the human body S can include an organ. In this case, the organ can be at least one of a respiratory organ S1, a digestive organ S2, a reproductive organ S3, and a urinary organ S4.

[0046] Here, the ultrasound irradiation unit 110 can irradiate ultrasound waves based on an electronic beam steering method, in which, when the position of a target focal point is changed, the electronic beam steering can apply ultrasound energy to the focal point with a preset time delay.

[0047] The acquisition unit 120 is provided in the transducer array 111 and can acquire cavitation information within the human body S while ultrasound is being irradiated. In this case, the acquisition unit 120 may include a passive cavitation detector (PCD) for monitoring and acquiring cavitation. For example, the acquisition unit 120 can acquire cavitation information generated from at least one of the respiratory organs S1, the digestive organs S2, the reproductive organs S3, and the urinary organs S4. Here, cavitation refers to a phenomenon in which cavities are generated in a fluid due to a change in pressure caused by a change in the velocity of the fluid. Here, cavitation refers to a phenomenon in which the pressure of a liquid drops below the vapor pressure when the liquid moves at a high speed, generating vapor bubbles in the liquid.

[0048] The present disclosure can efficiently acquire cavitation sensing signals because the acquisition position of the acquisition unit 120 for acquiring cavitation information changes according to the position of the transmission signal of the ultrasound irradiation unit 110. Furthermore, the present disclosure can accurately confirm the position where ultrasound is focused using a PCD, and can visualize and confirm the process of tumor degeneration during ultrasound irradiation.

[0049] The control unit 130 may be implemented as a memory 131 that stores data related to an algorithm or a program that reproduces the algorithm for controlling the operation of the components within the device, and at least one processor 132 that performs the above-described operations using the data stored in the memory 131. Here, the memory 131 and the processor 132 may be implemented on separate chips, or the memory 131 and the processor 132 may be implemented on a single chip.

[0050] The memory 131 can store data supporting various functions of the device, programs for the operation of the control unit, input / output data, a number of application programs (or applications) run by the device, and data and commands for the operation of the device. At least some of these application programs can be downloaded from an external server via wireless communication.

[0051] Such memory 131 may include at least one type of storage medium selected from the group consisting of flash memory type, hard disk type, solid state disk type (SSD type), silicon disk drive type (SDD type), multimedia card micro type, card-type memory (e.g., SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk. Furthermore, memory 131 may be a database separate from the device but connected by wire or wirelessly.

[0052] Based on the cavitation information, the processor 132 can control the ultrasound irradiation unit 110 so that the ultrasound irradiation unit 110 applies the ultrasound energy that has already been set in association with the focal point for each irradiation area of ​​the human body S, or does not apply ultrasound energy.

[0053] Here, the processor 132 can determine the process of tumor degeneration based on the cavitation information. At this time, the processor 132 can control the ultrasound irradiation unit 110 to adjust the ultrasound energy or stop irradiation if the pre-set cavitation information is not acquired by irradiating ultrasound energy. Furthermore, the processor 132 can control the ultrasound irradiation unit 110 to adjust the ultrasound energy or stop irradiation if cavitation is acquired in an area other than the area set to irradiate ultrasound.

[0054] The processor 132 can determine the acquisition position of the acquisition unit 120 for acquiring cavitation information according to the position of the transmission signal of the ultrasound irradiation unit 110. In this case, when the transmission path of the ultrasound irradiation unit 110 changes, the processor 132 can control the acquisition position of the acquisition unit 120 so that the cavitation information is acquired based on the cavitation channel that has already been set in association with the changed transmission path.

[0055] The processor 132 can control the ultrasound irradiation unit 110 to apply ultrasound energy with a pre-set time delay for each position of the transmission signal of the ultrasound irradiation unit 110. In addition, the processor 132 can control the ultrasound irradiation unit 110 to apply ultrasound energy with at least one of a pre-set irradiation time and intensity in conjunction with the position of the transmission signal of the ultrasound irradiation unit 110 and a focal point for each irradiation site of the human body S.

[0056] Fig. 4 is a flowchart showing an example of an ultrasonic wave irradiation method according to the present disclosure. Fig. 5 is a flowchart showing another example of an ultrasonic wave irradiation method according to the present disclosure.

[0057] 6 to 8 are diagrams showing an example of the process in which the transducer array of the ultrasound irradiation unit irradiates ultrasound.

[0058] Referring to Figures 4 to 8, the ultrasound irradiation method may include a position designation step (S410), an extraction step (S420), an irradiation step (S430), an acquisition step (S440), a judgment step (S451, S452), and an energy adjustment or irradiation termination step (S460).

[0059] When the position of the irradiation site of the human body S is specified via the ultrasound irradiation unit 110 (S410), the processor 132 can extract ultrasound energy information to be applied to the focal point of the irradiation site of the human body S from the ultrasound energy information to be applied to the focal point for each irradiation site that has already been set (S420).

[0060] Here, the irradiation site may be at least one of a tumor in a respiratory organ S1, a digestive organ S2, a reproductive organ S3, and a urinary organ S4, and the ultrasound energy information may be at least one of irradiation time and intensity.

[0061] For example, the processor 132 may extract, from the previously set ultrasound energy information, ultrasound energy information to be applied to a first focal point FP1 for each irradiation site of the human body S. In this case, the ultrasound energy information may be at least one of a first irradiation time and a first intensity to be applied to the first focal point FP1 corresponding to at least one of a tumor in an organ S1 of the respiratory organs, an organ S2 of the digestive organs, an organ S3 of the reproductive organs, and an organ S4 of the urinary organs.

[0062] As another example, the processor 132 may extract, from the previously set ultrasound energy information, ultrasound energy information to be applied to a second focal point FP2 for each irradiation site of the human body S. In this case, the ultrasound energy information may be at least one of a second irradiation time and a second intensity to be applied to the second focal point FP2 corresponding to at least one of a tumor in an organ S1 of the respiratory organs, an organ S2 of the digestive organs, an organ S3 of the reproductive organs, and an organ S4 of the urinary organs.

[0063] As yet another example, the processor 132 may extract, from the previously set ultrasound energy information, ultrasound energy information to be applied to a third focal point FP3 for each irradiation site of the human body S. In this case, the ultrasound energy information may be at least one of a third irradiation time and a third intensity to be applied to the third focal point FP3 corresponding to at least one of a tumor in an organ S1 of the respiratory organs, an organ S2 of the digestive organs, an organ S3 of the reproductive organs, and an organ S4 of the urinary organs.

[0064] In this case, the first irradiation time, the second irradiation time, and the third irradiation time may be different from each other, and the first intensity, the second intensity, and the third intensity may be different from each other.

[0065] The processor 132 can control the ultrasound irradiation unit 110 to apply ultrasound energy at at least one of the previously set irradiation time and intensity in conjunction with the position of the transmission signal of the ultrasound irradiation unit 110 and the focal point of the irradiation site of the human body S (S430).

[0066] For example, the processor 132 can control the ultrasound irradiation unit 110 so that the transducer array 111 applies ultrasound energy at at least one of a first irradiation time and a first intensity that have already been set in conjunction with a first focal point FP1 corresponding to at least one of a tumor in an organ of the respiratory system S1, an organ of the digestive system S2, an organ of the reproductive system S3, and an organ of the urinary system S4.

[0067] As another example, the processor 132 can control the ultrasound irradiation unit 110 so that the transducer array 111 applies ultrasound energy at at least one of a second irradiation time and a second intensity that have already been set in conjunction with a second focal point FP2 corresponding to at least one of a tumor in an organ S1 of the respiratory system, an organ S2 of the digestive system, an organ S3 of the reproductive system, and an organ S4 of the urinary system.

[0068] As yet another example, the processor 132 can control the ultrasound irradiation unit 110 so that the transducer array 111 applies ultrasound energy at at least one of a third irradiation time and a third intensity that have already been set in conjunction with a third focal point FP3 corresponding to at least one of a tumor in an organ S1 of the respiratory system, an organ S2 of the digestive system, an organ S3 of the reproductive system, and an organ S4 of the urinary system.

[0069] The processor 132 can acquire cavitation information within the human body S while the ultrasound is being irradiated through the acquisition unit 120 (S440). Here, the processor 132 can determine the process of tumor degeneration based on the cavitation information. In this case, the acquisition unit 120 can include a PCD (Passive Cavitation Detector) for monitoring and acquiring cavitation. For example, the processor 132 can acquire cavitation information generated from at least one of tumors in the respiratory organ S1, the digestive organ S2, the reproductive organ S3, and the urinary organ S4 through the acquisition unit 120.

[0070] That is, as shown in FIG. 6, the transducer array 111 can form electronic beam steering paths BSP1, BSP2, and BSP3 according to the focal points FP1, FP2, and FP3.

[0071] For example, the transducer array 111 can form a first electronic beam steering path BSP1 in response to a first focal point FP1. As another example, the transducer array 111 can form a second electronic beam steering path BSP2 in response to a second focal point FP2. As yet another example, the transducer array 111 can form a third electronic beam steering path BSP3 in response to a third focal point FP3.

[0072] Thereafter, the processor 132 can determine at least one of the acquisition position and acquisition angle of the acquisition unit 120 for acquiring cavitation information according to the position of the transmission signal of the transducer array 111. In this cavitation information acquisition process, when ultrasound is irradiated based on an electronic beam steering method, the transmission signal of the transducer array 111 is output in a state where the beam position changes in real time, so the transmission path is continuously changed and accurate cavitation information cannot be acquired.

[0073] Therefore, the present disclosure can determine at least one of the acquisition position and acquisition angle of the acquisition unit 120 for acquiring cavitation information according to the position of the transmission signal of the transducer array 111.

[0074] Here, as shown in Figure 7, when the transmission paths TXP1, TXP2, and TXP3 of the transducer array 111 change, the processor 132 can control at least one of the acquisition position and acquisition angle of the acquisition unit 120 so as to acquire cavitation information based on the cavitation channels CCH1, CCH2, and CCH3 that have already been set in conjunction with the changed transmission paths TXP1, TXP2, and TXP3.

[0075] For example, the processor 132 may control at least one of the acquisition position and acquisition angle of the acquisition unit 120 so as to acquire cavitation information through the first cavitation channel CCH1 and the first reception path RXP1 that have been previously set in association with the first transmission path TXP1. In this case, the acquisition unit 120 may acquire cavitation information corresponding to the first focal point FP1 for each irradiation region of the human body S.

[0076] As another example, the processor 132 may control at least one of the acquisition position and acquisition angle of the acquisition unit 120 to acquire cavitation information via the second cavitation channel CCH2 and the second receive path RXP2 that have already been set in association with the second transmit path TXP2. In this case, the acquisition unit 120 may acquire cavitation information corresponding to the second focus point FP2 for each irradiation region of the human body S.

[0077] As another example, the processor 132 may control at least one of the acquisition position and acquisition angle of the acquisition unit 120 to acquire cavitation information via the third cavitation channel CCH3 and the third receive path RXP3 that have already been set in association with the third transmit path TXP3. In this case, the acquisition unit 120 may acquire cavitation information corresponding to the third focus point FP3 for each irradiation region of the human body S.

[0078] 4, the processor 132 can determine whether pre-set cavitation information has been acquired by irradiating ultrasonic energy (S451). At this time, if pre-set cavitation information has been acquired by irradiating ultrasonic energy, the processor 132 can control the ultrasonic irradiation unit 110 to irradiate ultrasonic waves and apply the pre-set ultrasonic energy in association with a focal point for each irradiation region of the human body S (S430). For example, if pre-set first cavitation information has been acquired by irradiating a first ultrasonic energy, the processor 132 can control the ultrasonic irradiation unit 110 to apply the pre-set first ultrasonic energy in association with a focal point for each irradiation region of the human body S.

[0079] As shown in FIG. 5, the processor 132 can determine whether a reaction has occurred in an area other than the area set to be irradiated with ultrasonic waves, based on whether cavitation has been acquired (S452).

[0080] At this time, if a reaction occurs only in the area set to be irradiated with ultrasound, the processor 132 can control the ultrasound irradiation unit 110 to continue irradiating ultrasound and apply the previously set ultrasound energy in conjunction with the focal points for each irradiation area of ​​the human body S (S430).

[0081] For example, if the processor 132 determines that no cavitation is detected in areas other than the irradiation area and that a tissue reaction has occurred only in the target area, it can control the ultrasound irradiation unit 110 to apply the previously set ultrasound energy in conjunction with the focal point for each irradiation area of ​​the human body S.

[0082] The processor 132 can also control the ultrasound irradiation unit 110 so as to apply ultrasound energy with a time delay that has already been set for each position of the transmission signal of the transducer array 111 .

[0083] For example, as shown in FIG. 8 , the processor 132 may control the ultrasound emitter 110 to set a first focal point FP1 by applying time delays D1-D5 that cause the transducer array 111 to reach a central portion of at least one of a tumor in a respiratory organ S1, a digestive organ S2, a reproductive organ S3, or a urinary organ S4 at different ultrasound irradiation times T1, and to apply ultrasound energy at at least one of a first irradiation time and a first intensity that have been previously set in association with the first focal point FP1. In this case, the time delays D1-D5 in the T1 form may become shorter as they move from the central portion to a first position further away from the central portion and a second position further away from the central portion. That is, the time delay D5 closer to the first focal point FP1 may be set to be longer than the other time delays D1-D4. However, the present disclosure is not limited to this, and other forms of time delays may also be applied.

[0084] As another example, the processor 132 may control the ultrasound emitter 110 to set a second focal point FP2 by applying time delays D6-D11 that vary every ultrasound irradiation time T2 to a first position off the center of at least one of a tumor in the respiratory organ S1, the digestive organ S2, the reproductive organ S3, and the urinary organ S4, and to apply ultrasound energy at at least one of a second irradiation time and a second intensity that have been previously set in association with the second focal point FP2. In this case, the time delays D6-D11 in the T2 form may become shorter as the distance from the first position off the center increases toward the center and toward the second position off the center. The present disclosure is not limited to this, and other forms of time delays may also be applied.

[0085] As another example, the processor 132 may control the ultrasound emitter 110 to set a third focal point FP3 by applying time delays D12-D17 that vary every ultrasound irradiation time T3 to a second position off the center of at least one of a tumor in the respiratory organ S1, the digestive organ S2, the reproductive organ S3, and the urinary organ S4, and to apply ultrasound energy at at least one of a third irradiation time and a third intensity that have been previously set in association with the third focal point FP3. In this case, the time delays D12-D17 in the form of T3 may become shorter as the distance from the second position off the center increases toward the center and the first position off the center. This is not a limitation, and other forms of time delays may also be applied in the present disclosure.

[0086] When the previously set cavitation information is not acquired by irradiating the ultrasonic energy (S451), the processor 132 can control the ultrasonic irradiation unit 110 so that the ultrasonic irradiation unit 110 adjusts the ultrasonic energy or stops irradiation (S460). For example, when the previously set first cavitation information is not acquired by irradiating the first ultrasonic energy but the second cavitation information is acquired, the processor 132 can control the ultrasonic irradiation unit 110 to stop irradiating the ultrasonic energy.

[0087] In addition, if cavitation is detected in an area other than the area set for ultrasonic irradiation (S452), the processor 132 can control the ultrasound irradiation unit 110 to adjust the ultrasound energy or stop irradiation (S460). For example, if cavitation is detected in an area other than the area of ​​the irradiation site and it is determined that a tissue reaction has occurred, the processor 132 can control the ultrasound irradiation unit 110 to stop ultrasonic irradiation. That is, when ultrasound is irradiated to the first focal point FP1 for each irradiation site, if cavitation information is not acquired at the first focal point FP1 for each irradiation site via the acquisition unit 120 but cavitation information is acquired at the second focal point FP2 for each irradiation site or the third focal point FP3 for each irradiation site, the processor 132 can control the ultrasound irradiation unit 110 to adjust the ultrasound energy or stop irradiation.

[0088] The present disclosure can ensure stability during ultrasound irradiation by adjusting the ultrasound energy or halting irradiation if the previously set cavitation information is not obtained by irradiating ultrasound energy, or if a reaction occurs in an area other than the area set to be irradiated with ultrasound.

[0089] The ultrasound irradiation device 100 according to the present disclosure can accurately irradiate ultrasound to a specific irradiation site of the human body without damaging normal tissue in the human body, thereby improving the accuracy of ultrasound irradiation.

[0090] Furthermore, the ultrasound irradiation device 100 according to the present disclosure can adjust and irradiate ultrasound under optimal conditions for each irradiation area of ​​the human body, thereby maximizing the effect of ultrasound irradiation while shortening the irradiation time.

[0091] On the other hand, the present disclosure also allows ultrasound to be irradiated to different areas of the skin.

[0092] In this case, the present disclosure can also control the ultrasound irradiation unit 110 so that when the ultrasound irradiation unit 110 irradiates ultrasound to each irradiation area of ​​the skin according to the ultrasound irradiation conditions, the ultrasound irradiation unit 110 is irradiated to the irradiation area of ​​the skin at at least one of the depth and intensity corresponding to the ultrasound irradiation conditions based on mapping information in which the ultrasound irradiation conditions already set are mapped to depth information and position information regarding the irradiation area of ​​the skin.

[0093] For example, the ultrasound irradiation conditions may relate to the purpose of ultrasound irradiation, such as increasing fat, reducing fat, adding elasticity to the dermis, improving skin texture, suppressing wrinkles and acne, reducing pain, lifting the jawline in the case of removing cheek fat, lifting or tightening the skin, etc. In addition, the purpose of ultrasound irradiation may be to irradiate ultrasound to different skin layers for skin improvement, or to irradiate ultrasound to different body parts for body tissue improvement.

[0094] As another example, the ultrasound irradiation conditions may relate to target ultrasound irradiation conditions according to the depth of ultrasound irradiation for each skin layer, and may be for irradiating at least one of the forehead, lower jaw, nasolabial folds, around the eyes, nose, and upper arms with ultrasound at a specific temperature and specific energy to at least one of the papillary layer, upper dermis, lower dermis, upper fat, fat layer, sma, and fascia. Additionally, the target ultrasound irradiation conditions according to the depth of ultrasound irradiation for each skin layer may be for irradiating ultrasound under target conditions while changing the depth of ultrasound irradiation for each skin layer for skin improvement, or for irradiating ultrasound under target conditions while changing the depth of ultrasound irradiation for each body irradiation site for body tissue improvement.

[0095] The present disclosure can also control the ultrasound irradiation unit 110 so that ultrasound is irradiated differently at at least one of the focal depth, irradiation position, intensity, and irradiation time that have already been set for each skin layer or each irradiation site of the human body according to the ultrasound irradiation conditions.

[0096] Here, the focal depth may be at least one of a deep depth, a medium depth, and a shallow depth that have been previously set for each skin layer or each body region to be irradiated according to the ultrasound irradiation conditions. The irradiation position may be a full position or a partial position that have been previously set for each skin layer or each body region to be irradiated according to the ultrasound irradiation conditions. The intensity may be at least one of a strong intensity, a medium intensity, and a weak intensity that have been previously set for each skin layer or each body region to be irradiated according to the ultrasound irradiation conditions. The irradiation time may be at least one of a fast irradiation time, an average irradiation time, and a slow irradiation time that have been previously set for each skin layer or each body region to be irradiated according to the ultrasound irradiation conditions. In this case, the present disclosure may improve the effect of ultrasound irradiation by controlling the irradiation time at a fast interval and raising the temperature again before the temperature drops.

[0097] Meanwhile, since the spacing between skin layers may be different for each person within a given area, the present disclosure may be configured to finely adjust at least one of the ultrasound focusing depth, ultrasound irradiation position, ultrasound intensity, and ultrasound irradiation time within the given area.

[0098] In addition, the present disclosure can also control at least one of the angle and irradiation direction of the ultrasound irradiation unit 110 based on at least one of the angle information and irradiation direction information so that ultrasound is accurately irradiated to the skin layer or the irradiated area of ​​the human body at at least one of the depth and intensity corresponding to the ultrasound irradiation conditions.

[0099] At least one component may be added or removed depending on the performance of the components shown in Figures 1, 2, 3, 6 to 8. Furthermore, it is easily understood by those skilled in the art that the relative positions of the components may be changed depending on the performance or structure of the system.

[0100] Although Figures 4 and 5 show multiple steps being performed sequentially, this is merely an illustrative example of the technical idea of ​​this embodiment, and a person having ordinary skill in the art to which this embodiment pertains can modify and alter the order shown in Figures 4 and 5 or perform one or more of the multiple steps in parallel within the scope of the essential characteristics of this embodiment, and therefore Figures 4 and 5 are not limited to a chronological order.

[0101] Meanwhile, the disclosed embodiments may be embodied in the form of a recording medium storing computer-executable instructions. The instructions may be stored in the form of program code, which, when executed by a processor, may generate program modules to perform the operations of the disclosed embodiments. The recording medium may be embodied as a computer-readable recording medium.

[0102] The computer-readable recording medium includes any type of recording medium that stores computer-readable instructions, such as at least one of a ROM (Read Only Memory), a RAM (Random Access Memory), a magnetic tape, a magnetic disk, a flash memory, and an optical data storage device.
