Description

Technical Field

[0001] This invention relates to the field of medical imaging, and more particularly to an imaging system with adjustable radiation range. Background Technology

[0002] Oral cancer is a general term for malignant tumors occurring in the oral cavity, which includes the lips, buccal mucosa (the lining of the lips and cheeks), teeth, the floor of the mouth below the tongue, the anterior two-thirds of the tongue, the front part of the roof of the mouth, the gums, and a small area behind the molars. To examine abnormal tissues in the oral cavity, an oral mucosal examination is performed, by the doctor visually inspecting or palpating the oral mucosa. For laryngeal cancer, X-rays, CT scans, and MRI scans can determine the extent of invasion into surrounding tissues and organs and the degree of metastasis. Superficial ultrasound imaging can observe metastatic lymph nodes and their relationship with surrounding tissues. Because oral and laryngeal cancers occur in close proximity, using different instruments for diagnosis in the early stages wastes medical resources and increases patient suffering and financial burden; therefore, a universal diagnostic system is needed.

[0003] For example, patent application number CN201510145456.1, entitled "A Non-invasive Wearable Medical Examination System and Method," discloses a non-invasive wearable medical examination system and method belonging to the field of medical testing and internet application technology. It includes a wearable testing device for emitting signals to scan the human body and obtain scan results; a network server for receiving the scan results from the wearable testing device, comparing and calculating the scan results with standard data in the network server, and obtaining calculation results; and a client for receiving the calculation results and displaying them to the user in graphical, tabular, or data format, and generating a health evaluation report. This invention's non-invasive wearable medical examination system allows for timely medical examinations at home or other locations, with accuracy comparable to hospital examinations. Through signal collection, analysis, and calculation, it derives complete medical examination information for the examinee without trauma. Combined with wearable devices, it is more convenient and flexible to use, eliminating the cumbersome procedures of traditional medical examinations. Although this patent can achieve non-invasive detection using electromagnetic waves and radiation imaging in the lesion area, its radiation source and radiation detection device are both set outside the human body. This results in a wide radiation range from the radiation source, which may cause excessive harm to the human body. In addition, compared to imaging inside the human body, the images produced by this invention are relatively unclear and are accompanied by ghosting, which may easily lead to misdiagnosis by doctors.

[0004] Application No. 201610037472.3 discloses an oral cavity detection device, comprising: a first housing; a first motor disposed within the first housing; a processor disposed within the first housing; a second housing having an opening, the second housing being embedded into the first housing and connected to a rotating shaft of the first motor, the second housing extending relative to the first housing in a first direction; and an image capturing module fixed within the second housing and electrically coupled to the processor, wherein the image capturing module has a sampling direction passing through the opening of the second housing, and the sampling... The direction is perpendicular to the first vector; a filter holder is disposed between the image capturing module and the second housing, the filter holder having multiple filters and a light-transmitting port; a second motor is disposed in the second housing; wherein the first motor is used to rotate the second housing, causing the second housing to rotate around the first vector, when the first motor rotates the second housing, the image capturing module is used to acquire multiple images and transmit the images to the processor, the second motor is used to move the filter holder, so that one of the filters and the light-transmitting port is located between the opening of the second housing and the image capturing module. This patent can conveniently penetrate into the patient's oral cavity and capture full-mouth images, and because multiple light-emitting modules and filters of different wavelengths are set in the oral cavity detection device, more than two fluorescence-bonded images can be captured at once. However, this patent is an immersion detection method, and its structure is complex and its application range is narrow.

[0005] Therefore, it is necessary to provide a detection device with a wide range of applications that can provide clear imaging while minimizing the harm of electromagnetic radiation to the human body. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an imaging system with adjustable radiation range.

[0007] This invention provides an imaging system with adjustable radiation range, employing the following technical solution:

[0008] An adjustable radiation range imaging system includes a detection device for detecting electromagnetic waves emitted towards and transmitted through a patient's lesion area; an image processing device coupled to the detection device for receiving and processing image data transmitted by the detection device; a power supply for powering the system; and an adjustable radiation source for emitting electromagnetic waves towards the patient's lesion area. The adjustable radiation source comprises a base, an inflatable shielding device to limit the radiation range, and the radiation source itself. The base is a hollow structure, with the radiation source fixed to the bottom. The inflatable shielding device is connected to the base. An inflation tube is connected to the top of the base, and the other end of the inflation tube is connected to an external inflation device. The inner wall of the inflatable shielding device is coated with an electromagnetic wave shielding coating.

[0009] Preferably, the shielding inflation device is a shielding airbag, and the two sides of the base are symmetrically connected with shielding airbags that are inflated to limit the radiation range.

[0010] The base has symmetrical rotating rods on both sides of the lower part. The rotating rods are fixedly connected to the top of the two shielding airbags. When the shielding airbags are inflated, the rotating rods are rotated by force, which drives the shielding airbags to limit the radiation range.

[0011] Preferably, the base has an annular shielding air ring connected to its side.

[0012] Preferably, the electromagnetic wave shielding coating is made of non-metallic powder.

[0013] Preferably, the electromagnetic wave shielding coating is made of graphite powder.

[0014] Preferably, the inflation tube communicating with the top of the base is made of PVC. The purpose is to increase the pressure resistance of the tube and prevent it from bursting during inflation.

[0015] Compared with the prior art, the present invention has the following technical effects:

[0016] (1) The present invention can set the radiation source to a size that can enter the human body and irradiate and image inside the body; it can also set the detection device to a size that can enter the human body and irradiate and image inside the body, which can avoid the ghosting caused when the radiation source and detection device are set outside the human body for detection, and greatly reduce the chance of doctors misjudging.

[0017] (2) The present invention can adjust the radiation area according to the size of the patient's lesion area, so as to irradiate it precisely and greatly reduce the damage to the human body caused by the excessive radiation range of the radiation source.

[0018] (3) When the radiation source is placed inside the human body, it can be inflated and fixed inside the human body, which reduces the trouble caused by the inability to fix it and allows for adjustment of the radiation range, which is very convenient.

[0019] (4) This invention is simple and has a wide range of applications. It can be placed outside the body to detect oral cavity, trachea and urinary system, or it can be used for immersion detection. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] Example

[0027] like Figure 1 As shown, an adjustable radiation range imaging system of the present invention includes a detection device 1 for detecting electromagnetic waves emitted towards and transmitted through the lesion area of ​​a patient; an image processing device 2 coupled to the detection device 1 for receiving image data transmitted by the detection device 1 and processing the image; a power supply 4 for powering the system; and an adjustable radiation source 3 for emitting electromagnetic waves towards the lesion area of ​​the patient. The adjustable radiation source 3 consists of a base 31, an inflatable shielding device for limiting the radiation range, and a radiation source 33. The base 31 has a hollow structure, the radiation source 33 is fixed to the bottom of the base 31, and the shielding inflatable device is connected to the base 31. An inflation tube 34 is connected to the top of the base 31, and the other end of the inflation tube 34 is connected to an external inflation device 5. The inner wall of the shielding inflatable device is coated with an electromagnetic wave shielding coating, which avoids unnecessary damage caused by contact between the coating and the human body.

[0028] The aforementioned detection device 1 can be a commercially available electromagnetic wave detection device. When using a non-invasive method to image the interior of an object by irradiating it with electromagnetic waves and detecting electromagnetic waves that penetrate the object, it is used to receive electromagnetic waves and convert them into electrical signals.

[0029] The image processing device 2 mentioned above can be a commercially available image processor, which can convert the electrical signal of the detection device 1 into an image signal for the doctor to view.

[0030] The aforementioned external inflation device 5 can be a common inflation device available on the market. The detection device 1, the image processing device 2, and the adjustable radiation source 3 are separate.

[0031] When this invention is used, the adjustable radiation source 3 can be set outside the patient's body, and the detection device 1 can be set to a smaller size so that it can be inserted into the lesion area inside the patient's body to cooperate with the adjustable radiation source 3 for imaging; or the adjustable radiation source 3 can be set to a smaller size to be inserted into the lesion area inside the patient's body to cooperate with the detection device 1 set outside the patient's body for imaging.

[0032] When this invention is used, the adjustable radiation source 3 is placed outside the patient's body. The external inflation device 5 of this invention is activated, and gas enters the base 31 through the inflation tube 34. Gas then enters the shielding inflation device connected to the base 31, causing it to expand and shield the scattered electromagnetic waves, allowing it to accurately irradiate the lesion area of ​​the patient. This works in conjunction with the lesion area detection device 1 implanted inside the patient's body to create an image, thereby reducing the harm of electromagnetic waves to the human body. The inner wall of the shielding inflation device is coated with an electromagnetic wave shielding coating. Applying this coating to the inner wall prevents unnecessary damage when the coating comes into contact with the human body and also blocks the scattering of electromagnetic waves.

[0033] When this invention is used, the adjustable radiation source 3 is positioned within the patient's body to accommodate its size, avoiding unnecessary discomfort. The adjustable radiation source 3 extends into the area to be examined within the patient's body. The external inflation device 5 is activated, and gas enters the base 31 through the inflation tube 34, then flows into a shielding inflation device connected to the base 31. This shielding inflation device expands, increasing the cross-sectional area of ​​the adjustable radiation source 3 to fix it within the patient's body and shielding scattered electromagnetic waves, thus reducing electromagnetic radiation damage to the human body. The inner wall of the shielding inflation device is coated with an electromagnetic wave shielding coating. Applying this coating to the inner wall prevents unnecessary damage from contact with the human body and also blocks electromagnetic wave scattering.

[0034] An imaging system with adjustable radiation range according to the present invention can be applied to the oral cavity system, pharyngeal system, and urinary system.

[0035] Preferred embodiment 1

[0036] like Figure 1 As shown, in this embodiment, the shielding inflation device is a shielding airbag 321, and the base 31 has shielding airbags 321 that are inflated to limit the radiation range on both sides.

[0037] The electromagnetic wave shielding coating is made of non-metallic powder, such as carbon ash.

[0038] The inflation tube 34, which communicates with the top of the base 31, is made of PVC to increase the pressure resistance of the tube and prevent it from bursting during inflation.

[0039] like Figure 4 As shown, in use, the user inserts the adjustable radiation source 3 into the human body and operates the external inflation device 5 to begin inflation. The shielding airbag 321 begins to expand and fix the adjustable radiation source 3, and then continues to expand and bend towards the radiation source 33. The electromagnetic wave shielding coating on the inner surface begins to block electromagnetic wave radiation, preventing the human body from being harmed by electromagnetic waves. The radiation source 33 of the adjustable radiation source 3 begins to work. The detection device 1 receives the electromagnetic waves emitted towards and transmitted through the patient's lesion area, and then converts them into image signals, which are sent to the image processing device 2 coupled with it for processing and imaging, for doctors to observe and diagnose.

[0040] Preferred embodiment 2

[0041] like Figure 2 As shown in the preferred embodiment of the above embodiment, in this embodiment, rotating rods 322 are symmetrically and movably connected to the lower parts of both sides of the base 31. The rotating rods 322 are fixedly connected to the top of the two shielding airbags 321. When the shielding airbags 321 are inflated, the rotating rods 322 are rotated by force, which drives the shielding airbags 321 to limit the radiation range.

[0042] The electromagnetic wave shielding coating is made of non-metallic powder, such as resin.

[0043] The inflation tube 34, which communicates with the top of the base 31, is made of PVC to increase the pressure resistance of the tube and prevent it from bursting during inflation.

[0044] In use, the user inserts the adjustable radiation source 3 into the body and operates the external inflation device 5 to begin inflation. The shielding airbag 321 begins to expand and fix the adjustable radiation source 3. As it continues to expand, the rotating rod 322 rotates under force, causing the shielding airbag 321 to bend towards the radiation source 33. The electromagnetic wave shielding coating on its surface begins to block electromagnetic wave radiation, preventing the human body from being harmed by electromagnetic waves. The rotating rod 322 allows the shielding airbag 321 to bend more effectively towards the radiation source 33, thus better preventing electromagnetic wave scattering.

[0045] When the adjustable radiation source 33 starts working, the detection device 1 receives the electromagnetic waves emitted towards and transmitted through the lesion area of ​​the patient, and then converts them into image signals, which are sent to the image processing device 2 coupled with it for processing and imaging, so that doctors can observe and diagnose. This invention can produce clear images.

[0046] Preferred Example 3

[0047] like Figure 3As shown, in this embodiment, the base 31 has an annular shielding air ring 323 connected to its side.

[0048] The electromagnetic wave shielding coating is made of graphite powder.

[0049] The inflation tube 34, which communicates with the top of the base 31, is made of PVC to increase the pressure resistance of the tube and prevent it from bursting during inflation.

[0050] When using this invention, the user inserts the adjustable radiation source 3 into the human body and operates the external inflation device 5 to start inflation. The annular shielding inflation ring 323 begins to expand and fix the adjustable radiation source 3, and then continues to expand downwards, forming a ring around the radiation source 33, thereby effectively preventing electromagnetic wave scattering.

[0051] When the adjustable radiation source 3 starts working, the detection device 1 receives the electromagnetic waves emitted towards and transmitted through the lesion area of ​​the patient, and then converts them into image signals, which are sent to the image processing device 2 coupled with it for processing and imaging, so that doctors can observe and diagnose. This technical solution can achieve clear imaging and reduce the misdiagnosis rate.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
