Description
本揭示是關於一種檢測裝置，特別是關於一種放射線射束檢測裝置。The present disclosure relates to a detection device, and more particularly to a radiation beam detection device.
放射技術已被廣泛地應用在現代醫學中，例如放射治療、放射診斷、核子醫學等。放射治療的原理是利用高能輻射與腫瘤細胞發生作用，使得腫瘤細胞被游離或激發而産生有毒自由基，進而造成腫瘤細胞傷害，或者直接以游離輻射所釋放的輻射能量造成癌細胞的脫氧核醣核酸發生斷鍵。放射劑量的多寡會直接影響放射線進入病患後對腫瘤細胞及正常組織的傷害程度。因此，放射治療的照射參數會配合定期的射束質量保證作業來確定病患所接受的放射劑量與處方劑量之誤差小於臨床治療可容許的範圍內。也就是說，放射治療技術需配合審慎的品保措施及劑量驗證才能確保病患的治療效果。Radiation technology has been widely used in modern medicine, such as radiation therapy, radiation diagnosis, nuclear medicine, and so on. The principle of radiation therapy is to use high-energy radiation to interact with tumor cells, causing tumor cells to be freed or excited to generate toxic free radicals, which can cause damage to tumor cells, or directly cause the cancer cells to deoxyribonucleic acid with radiation energy released by free radiation A key break occurred. The amount of radiation dose directly affects the degree of damage to tumor cells and normal tissues after the radiation enters the patient. Therefore, the radiation parameters of radiation therapy will be used in conjunction with regular beam quality assurance operations to determine that the error between the dose received by the patient and the prescribed dose is less than the allowable range for clinical treatment. In other words, radiotherapy technology needs to be combined with prudent quality assurance measures and dose verification to ensure the treatment effect of patients.
放射劑量與射束參數的控制可藉由射束的監控來達到，因此監控放射線射束的檢測裝置為放射治療必須的設備。現有的放射線射束檢測裝置包含充氣式偵測器、閃爍偵測器、和半導體偵測器。充氣式偵測器配置有游離腔(ion chamber)，其是利用放射線通過游離腔時與腔體內的氣體作用產生電荷，並且藉由外部電路擷取產生的電荷來量測輻射劑量與射束參數。閃爍偵測器配置有閃爍體(scintillator)。具體來說，請參照第1圖，其顯示現有技術的閃爍偵測器1之示意圖。閃爍偵測器1包含閃爍體11和接收器12。放射線射束13入射閃爍體11之後，閃爍體11產生光線並且藉由設置在後方的接收器12收集閃爍體11產生的光訊號。然而，放射線射束13會穿過閃爍體11直接照射到閃爍體11後方的接收器12，使得接收器12容易因輻射破壞而故障。再者，放射線射束13通過接收器12也會造成放射線射束13的檢測品質變差，所以此種閃爍偵測器1只能用於檢測低能量的X光，不適合用於檢測高能量治療型的放射線射束使用。The control of radiation dose and beam parameters can be achieved by monitoring the beam, so the detection device for monitoring the radiation beam is a necessary device for radiation therapy. Existing radiation beam detection devices include an inflatable detector, a scintillation detector, and a semiconductor detector. The gas-filled detector is equipped with an ion chamber, which uses the gas to interact with the gas in the chamber when radiation passes through the ion chamber, and uses an external circuit to capture the generated charges to measure the radiation dose and beam parameters. . The scintillation detector is provided with a scintillator. Specifically, please refer to FIG. 1, which shows a schematic diagram of the prior art flicker detector 1. The flicker detector 1 includes a scintillator 11 and a receiver 12. After the radiation beam 13 enters the scintillator 11, the scintillator 11 generates light and collects the light signals generated by the scintillator 11 through a receiver 12 disposed at the rear. However, the radiation beam 13 passes through the scintillator 11 and directly irradiates the receiver 12 behind the scintillator 11, so that the receiver 12 is susceptible to failure due to radiation damage. In addition, the radiation beam 13 passing through the receiver 12 will also cause the detection quality of the radiation beam 13 to deteriorate. Therefore, this flicker detector 1 can only be used to detect low-energy X-rays, and is not suitable for detecting high-energy therapy. Type radiation beam is used.
因此，現已發展出另一種將接收器移動到不會位在放射線射束行進路線的閃爍偵測器。請參照第2圖，其顯示現有技術的另一種閃爍偵測器2之示意圖。閃爍偵測器2包含暗室腔體21、壓克力假體(PMMA phantom)22、閃爍體23、攝影機24、和反射鏡25。閃爍偵測器2利用放射線射束26穿過壓克力假體22而照射到閃爍體23，使得射線射束26與閃爍體物質作用產生光，並且藉由攝影機24擷取產生的光訊號來獲得輻射劑量。然而，在現有的閃爍偵測器2的架構中，需要提供較大的空間來架設攝影機24，使得閃爍偵測器2的整體體積龐大不便於擺設。再者，由於攝影機24必須精準地架設在放射線射束26的行進路線之外，以免攝影機24被放射線射束26的輻射破壞，使得攝影機24的角度與位置校正困難。並且，在每次移動閃爍偵測器2之後必須重新校準攝影機24的位置，如此不僅耗時且在使用上也造成諸多不便。Therefore, another flicker detector has been developed that moves the receiver to a position that does not lie on the path of the radiation beam. Please refer to FIG. 2, which shows a schematic diagram of another flicker detector 2 in the prior art. The scintillation detector 2 includes a dark chamber cavity 21, an acrylic prosthesis (PMMA phantom) 22, a scintillator 23, a camera 24, and a reflector 25. The scintillation detector 2 uses the radiation beam 26 to pass through the acrylic prosthesis 22 and irradiate the scintillator 23, so that the radiation beam 26 interacts with the scintillator substance to generate light, and the generated light signal is captured by the camera 24 Obtain the radiation dose. However, in the existing architecture of the flicker detector 2, it is necessary to provide a large space for setting up the camera 24, so that the overall volume of the flicker detector 2 is huge and inconvenient to set up. Furthermore, since the camera 24 must be accurately positioned outside the travel path of the radiation beam 26 to prevent the camera 24 from being damaged by the radiation of the radiation beam 26, it is difficult to correct the angle and position of the camera 24. In addition, the position of the camera 24 must be recalibrated after each movement of the flicker detector 2, which is time-consuming and inconvenient in use.
有鑑於此，有必要提出一種放射線射束檢測裝置，能快速量測放射線射束且體積小易於裝設且不會被放射線射束的輻射直接照射而破壞，以解決習知技術中存在的問題。In view of this, it is necessary to propose a radiation beam detection device, which can quickly measure the radiation beam, is small in size and easy to install, and will not be damaged by being directly irradiated by the radiation of the radiation beam in order to solve the problems existing in the conventional technology .

爲了讓本揭示之上述及其他目的、特徵、優點能更明顯易懂，下文將特舉本揭示較佳實施例，並配合所附圖式，作詳細說明如下。In order to make the above and other objects, features, and advantages of the present disclosure more comprehensible, the following describes the preferred embodiments of the present disclosure and the accompanying drawings in detail, as follows.
請參照第3圖，其顯示本揭示之較佳實施例之放射線射束檢測裝置3之示意圖。放射線射束檢測裝置3包含閃爍體31、光接收器組32、和處理器33。閃爍體31是由閃爍物質構成，其中閃爍物質在吸收能量之後會放出可見光。光接收器組32設置在閃爍體31的外周圍。處理器33與光接收器組32通訊連接。本揭示之放射線射束檢測裝置3是藉由將放射線射束91進入閃爍體31，利用游離輻射將閃爍體31內的晶體或分子中的電子激發至激態，而當電子自激態回到基態時放出螢光，接著藉由光接收器組32將收集的螢光轉換為電訊號，並且藉由處理器33對電訊號進行一系列對應的處理進而完成輻射檢測。閃爍體31、光接收器組32、和處理器33的具體結構將於後詳述。Please refer to FIG. 3, which shows a schematic diagram of a radiation beam detection device 3 according to a preferred embodiment of the present disclosure. The radiation beam detection device 3 includes a scintillator 31, a light receiver group 32, and a processor 33. The scintillator 31 is composed of a scintillating substance, and the scintillating substance emits luminous light after absorbing energy. The light receiver group 32 is provided around the outer periphery of the scintillator 31. The processor 33 is communicatively connected with the optical receiver group 32. The radiation beam detection device 3 of the present disclosure is to enter the radiation beam 91 into the scintillator 31, and then excite the electrons in the crystals or molecules in the scintillator 31 to an excited state by means of free-running radiation, and when the electron self-excited state returns to In the ground state, the fluorescent light is emitted, and then the collected fluorescent light is converted into an electrical signal by the light receiver group 32, and the processor 33 performs a series of corresponding processing on the electrical signal to complete the epitaxial detection. The specific structures of the scintillator 31, the light receiver group 32, and the processor 33 will be described in detail later.
如第3圖所示，閃爍體31為矩形的平板件，然而，在其他實施例中閃爍體31可採用各種適當的形狀，不侷限於此。閃爍體31包含前表面311、後表面(未標示)、第一側表面312、第二側表面313，其中前表面311與後表面相對，且第一側表面312和第二側表面313彼此相鄰，以及第一側表面312和第二側表面313皆與前表面311和後表面相鄰。閃爍體31的前表面311與放射源9對準，用於接收放射源9發出的放射線射束91。放射線射束91沿著直線路徑911成角度地入射閃爍體31的前表面311。較佳地，放射線射束91垂直入射在閃爍體31的前表面311。在本實施例中，閃爍體31的前表面311設置在X-Y平面，以及放射線射束91沿著Z方向入射。放射線射束91穿過閃爍體31且從閃爍體31之後表面出射。As shown in FIG. 3, the scintillator 31 is a rectangular flat plate. However, in other embodiments, the scintillator 31 may adopt various suitable shapes, and is not limited thereto. The scintillator 31 includes a front surface 311, a rear surface (not labeled), a first side surface 312, and a second side surface 313. The front surface 311 is opposite to the rear surface, and the first side surface 312 and the second side surface 313 face each other. The first side surface 312 and the second side surface 313 are adjacent to the front surface 311 and the rear surface. The front surface 311 of the scintillator 31 is aligned with the radiation source 9 for receiving a radiation beam 91 emitted from the radiation source 9. The radiation beam 91 enters the front surface 311 of the scintillator 31 at an angle along a linear path 911. Preferably, the radiation beam 91 is incident perpendicularly on the front surface 311 of the scintillator 31. In the present embodiment, the front surface 311 of the scintillator 31 is disposed on the X-Y plane, and the radiation beam 91 is incident along the Z direction. The radiation beam 91 passes through the scintillator 31 and exits from the surface behind the scintillator 31.
如第4圖所示，光接收器組32包含第一光接收器321和第二光接收器322。第一光接收器321沿著第一方向(例如X方向)設置在閃爍體31之第一側表面312，用於獲取放射線射束91進入閃爍體31而產生之投射在第一側表面312且在第一方向上的第一光訊號，並且將第一光訊號轉換為第一電訊號。第二光接收器322沿著第二方向(例如Y方向)設置在閃爍體31之第二側表面313，用於獲取放射線射束91進入閃爍體31而產生之投射在第二側表面313且在第二方向上的第二光訊號，並且將第二光訊號轉換為第二電訊號。在本實施例中，第一方向和第二方向與放射線射束91的直線路徑911的延伸方向(例如Z方向)垂直。應當注意的是，第一光接收器321和第二光接收器322皆是設置在與放射線射束91之直線路徑911的延伸線912上彼此不干涉之位置。即，放射線射束91不會直接照射在第一光接收器321和第二光接收器322，並且放射線射束91穿過閃爍體31後射出的射束也不會直接照射在第一光接收器321和第二光接收器322。藉由將光接收器組32設置為不會位在放射線射束91的行進路線上，可有效地避免光接收器組32被放射線射束91直接轟擊而造成故障或損壞。藉此設計，放射線射束檢測裝置3可用於檢測具有高能量且高穿透特性的放射線射束，例如能量範圍在1 百萬電子伏特(mega electron Volt，MeV)到30 MeV之間的光子射束、能量範圍在1 MeV到30 MeV之間的電子射束、能量範圍在3 MeV到300 MeV之間的質子射束、或者是能量範圍在30 MeV/u到800 MeV/u之間的重粒子射束。As shown in FIG. 4, the optical receiver group 32 includes a first optical receiver 321 and a second optical receiver 322. The first light receiver 321 is disposed along the first direction (for example, the X direction) on the first side surface 312 of the scintillator 31, and is used to obtain the projection of the radiation beam 91 entering the scintillator 31 on the first side surface 312 and A first optical signal in a first direction, and the first optical signal is converted into a first electrical signal. The second light receiver 322 is disposed along the second direction (for example, the Y direction) on the second side surface 313 of the scintillator 31, and is used for acquiring the projection of the radiation beam 91 entering the scintillator 31 on the second side surface 313 and A second optical signal in a second direction, and the second optical signal is converted into a second electrical signal. In this embodiment, the first direction and the second direction are perpendicular to the extending direction (for example, the Z direction) of the linear path 911 of the radiation beam 91. It should be noted that each of the first light receiver 321 and the second light receiver 322 is disposed at a position that does not interfere with each other on the extension line 912 of the linear path 911 of the radiation beam 91. That is, the radiation beam 91 is not directly irradiated on the first light receiver 321 and the second light receiver 322, and the beam emitted after the radiation beam 91 passes through the scintillator 31 is not directly irradiated on the first light receiver. 321 and second light receiver 322. By arranging the light receiver group 32 so as not to be positioned on the traveling path of the radiation beam 91, it is possible to effectively avoid the failure or damage caused by the light receiver group 32 being directly bombarded by the radiation beam 91. With this design, the radiation beam detection device 3 can be used to detect radiation beams with high energy and high penetration characteristics, such as photon emission with an energy range between 1 mega electron Volt (MeV) to 30 MeV Beams, electron beams with an energy range between 1 MeV and 30 MeV, proton beams with an energy range between 3 MeV and 300 MeV, or heavy beams with an energy range between 30 MeV / u and 800 MeV / u Particle beam.
較佳地，第一光接收器321和第二光接收器322可為圖像感測器，例如接觸式影像感測器(contact image sensor，CIS)。並且，第一光接收器321、第二光接收器322是直接耦合在閃爍體31上，或者是藉由黏膠等物質間接耦合在閃爍體31上。藉此設計，光接收器組32不但可精確地捕捉到閃爍體31發出的可見光，還可使得放射線射束檢測裝置3的整體構型小型化、降低生產成本、方便設置等。Preferably, the first light receiver 321 and the second light receiver 322 may be image sensors, such as a contact image sensor (CIS). In addition, the first light receiver 321 and the second light receiver 322 are directly coupled to the scintillator 31, or are indirectly coupled to the scintillator 31 through a substance such as an adhesive. With this design, the light receiver group 32 can not only accurately capture the visible light emitted by the scintillator 31, but also make the overall configuration of the radiation beam detection device 3 compact, reduce production costs, and facilitate setting.

Optionally, the processor 33 may also communicate with the first optical receiver 321 and the second optical receiver 322 in a wireless manner, and is not limited thereto. The processor 33 may generate a relationship between the position of the radiation beam in the first direction or the second direction and the signal intensity according to the acquired first electrical signal or the second electrical signal. In addition, the processor 33 may also create a beam information map according to the obtained first and second electrical signals, which includes information such as the size, position, and intensity distribution of the radiation beam 91. Specifically, the processor 33 includes a data acquisition unit, a data processing unit, and an image processing unit. The processor 33 obtains the electric signal from the optical receiver group 32 through the data acquisition unit, and stores the electric signal to the data processing unit. The data processing unit can perform a variety of functions, such as gain correction, edge detection, sharpening, contrast enhancement, etc., to make the data suitable for subsequent processing or image reconstruction. The image processing unit receives the signals processed by the data processing unit to generate an image of a region of interest (ROI) passed by the radiation beam 91.
