本案係為一種肢體定位裝置，尤指應用於X光影像製作的肢體定位裝置。This case is a limb positioning device, especially a limb positioning device used in X-ray image production.

請參見圖1A，其係一從身後往前面所拍攝之左膝蓋X光影像圖，而圖1B則是傳統用來拍攝圖1A之膝蓋X光影像圖的習用系統配置示意圖。其中X光源11發出的X光投射至人體10後，在後方的影像板12上成像，而該影像板12可以是數位攝影板（DR）、電腦攝影板（CR）或是傳統底片中之一。Please refer to FIG. 1A , which is an X-ray image of the left knee taken from behind to the front, and FIG. 1B is a schematic configuration diagram of a conventional system for taking the X-ray image of the knee in FIG. 1A .

為能得到較精準的膝蓋骨骼影像來進行判斷，通常會讓X光的入射光和脛骨(Tibial)最上緣的脛骨平台(Tibial Plateau)19( 圖1A中的位置請確認)平行，也就是大約與水平線成θ1(例如10度左右)的入射角度(如圖1B中之所示)來進行X光拍攝，進而得到如圖1A中的骨骼成像。但因人體身高的四肢比例會因人而異，因此常需經過多次調整才能照出合格的X光影像來讓醫生進行病徵判讀，而且因拍攝角度與距離所造成影像樣本之間的變異量，也會對要將樣本進行機器學習的後續過程造成困擾。而如何改善拍攝角度不易調整與X光影像合格率不高的缺失，係為發展本案的主要目的。In order to obtain a more accurate knee bone image for judgment, the incident light of the X-ray is usually parallel to the Tibial Plateau 19 (please confirm the position in Figure 1A) on the uppermost edge of the tibia, that is, about X-ray shooting is performed at an incident angle of θ1 (for example, about 10 degrees) with the horizontal line (as shown in FIG. 1B ), and then the bone imaging as shown in FIG. 1A is obtained. However, because the ratio of body height to limbs varies from person to person, it often takes multiple adjustments to take a qualified X-ray image for doctors to interpret symptoms, and the amount of variation between image samples is caused by shooting angles and distances. , which will also cause troubles in the subsequent process of subjecting the samples to machine learning. How to improve the lack of difficulty in adjusting the shooting angle and the low pass rate of X-ray images is the main purpose of the development of this case.

From the positional relationship between the two, the deviation of the incident angle of the central beam in the X-ray beam can be interpreted, and the X-ray operation can be realized. Personnel make adjustments on the fly.

根據上述構想，本案所述之肢體定位裝置，其中該X光源是一點光源，其所散射出來的X光束會隨距離而涵蓋更大範圍，而藉由相鄰多組的圓點與線條間位置關係的不同，反推出該X光源與該標示板間的距離。According to the above idea, in the limb positioning device described in this case, the X light source is a point light source, and the X beam scattered by it will cover a larger range with the distance, and the positions between the adjacent groups of dots and lines According to the difference in relationship, the distance between the X light source and the sign board can be inversely deduced.

根據上述構想，本案所述之肢體定位裝置，其中每個圓點與線條，於其上或其側邊製作有相對應的預設編號或是預設標示，來代表其在整體數量的第幾個，而由完全對準的那一組的編號關係，便可以推估出該X光源所散射出來的X光束中之中心光束的通過位置，進而反推出該X光源的入射角度。According to the above idea, in the limb positioning device described in this case, each dot and line has a corresponding preset number or a preset mark on it or on its side to represent its position in the overall quantity. , and from the numbering relationship of the group that is completely aligned, the passage position of the central beam in the X-ray scattered by the X-ray source can be estimated, and then the incident angle of the X-ray source can be deduced in reverse.

根據上述構想，本案所述之肢體定位裝置，其中在得知與受測者膝蓋脛骨平台(Tibial Plateau)同一水平位置的圓點與線條的編號關係後，便可以利用查表或預設的算式來完成受測者身高的反推，進而將受測者身高的資料一併註記到此受測者的膝蓋X光影像圖中。According to the above idea, in the limb positioning device described in this case, after knowing the numbering relationship between the dots and the lines at the same horizontal position as the tibial plateau of the subject's knee, it can use the look-up table or the preset formula To complete the reverse deduction of the subject's height, and then record the data of the subject's height into the subject's knee X-ray image map.

根據上述構想，本案所述之肢體定位裝置，其中該標示板的第二部份還於線條兩側設有一第一參考板與一第二參考板，該第一參考板與該第二參考板用會吸收X光的材料來完成，兩個參考板吸收X光的能力不同，在影像感應片上的成像有不同的明暗程度，進而提供曝光強度校正程序的參考。According to the above idea, in the limb positioning device described in this case, the second part of the sign board is also provided with a first reference board and a second reference board on both sides of the line, and the first reference board and the second reference board It is done with materials that can absorb X-rays. The ability of the two reference plates to absorb X-rays is different, and the images on the image-sensing sheet have different degrees of brightness and darkness, thereby providing a reference for the exposure intensity correction procedure.

根據上述構想，本案所述之肢體定位裝置，其中該第一參考板與該第二參考板的材料為包含鋁的金屬材料，該第一參考板與該第二參考板的厚度不同。According to the idea above, in the limb positioning device described in this application, the materials of the first reference plate and the second reference plate are metal materials including aluminum, and the thicknesses of the first reference plate and the second reference plate are different.

根據上述構想，本案所述之肢體定位裝置，其中該第一參考板與該第二參考板的厚度相同但材料不同，或是厚度與材料皆相同但兩者的鏤空圖案不同，皆用來造成等效面積的不同。According to the above idea, in the limb positioning device described in this case, the thickness of the first reference plate and the second reference plate are the same but the materials are different, or the thickness and material are the same but the hollow patterns of the two are different. different equivalent areas.

根據上述構想，本案所述之肢體定位裝置，其中該立板主體使用壓克力或是工程塑膠的材料來完成，且該立板主體的正面還可設有至少一鏤空處，用以與本身材質來進行曝光強度的差異值比對，更設有一骨骼假體，用以提供曝光強度的參考標準基準值。According to the above idea, in the limb positioning device described in this case, the main body of the vertical board is completed with acrylic or engineering plastics, and the front of the main body of the vertical board can also be provided with at least one hollowed out place for matching with itself.

為了能對本發明之上述構想有更清楚的理解，下文特舉出多個實施例，並配合對應圖式詳細說明如下。In order to have a clearer understanding of the above-mentioned idea of the present invention, a number of embodiments are specifically cited below, and detailed descriptions are given below with corresponding drawings.

為能改善習用手段之缺失，本案係發展出如圖2所示之肢體定位裝置的構造示意圖，其中主要具有底座21以及立板22等構造，底座21中的底座主體210用以置放在地面，而圖3中所特別畫出之底座21中的腳部***211，其係用以引導被攝者的腳步站位（例如圖中所示之θ2(例如為5度)的外開角度）。至於立板22中立板主體220的背面2201設有可置放Ｘ光影像板（本圖未示出）的固定裝置（本圖未示出），至於立板主體220的正面2200則相對應該固定裝置而設置有一標示板221。In order to improve the lack of conventional means, this case developed a schematic diagram of the structure of the limb positioning device as shown in Figure 2, which mainly has a base 21 and a vertical plate 22 and other structures, and the base body 210 in the base 21 is used to place it on the ground , and the foot positioner 211 in the base 21 specially drawn in Fig. 3 is used to guide the footsteps of the subject (for example, the outward opening angle of θ2 (for example, 5 degrees) shown in the figure ). As for the back 2201 of the main body 220 of the vertical board 22, there is a fixing device (not shown in this figure) that can place the X-ray image plate (not shown in this figure), and the front 2200 of the main body 220 of the vertical board should be relatively fixed. The device is provided with a sign board 221 .

再請參見圖4，其係本案關於標示板221的較佳實施例構造分離示意圖，該標示板221的第一部份41的表面上設置有直線排列的圓點410（直徑可為2.9mm，但可視應用條件改變而調整），本例相鄰圓點410的圓心間距則為10mm（但也可視應用條件改變而調整）。而該標示板221的第二部份42則設置有平行排列的多個線條420，相鄰線條420中線的間距與該相鄰圓點410的圓心間距一致，同樣可以是10mm（但可視應用條件改變而調整），至於每個相對應的圓點410與線條420間的距離D，在本例為100mm（但也可視應用條件改變而調整）。而標示板221的第一部份41與第二部份42組合後才如圖2之設計。如此一來，當X光源11所散射出來的X光束中之中心光束，以θ3角度(例如10度，但可視應用條件改變而調整)入射至人體10的膝蓋脛骨平台(Tibial Plateau)19後，會在影像感應片上形成如圖5A、5B所示的圖案。Referring to Fig. 4 again, it is a schematic diagram of separation of the structure of the preferred embodiment of the signboard 221 in this case, the surface of the first part 41 of the signboard 221 is provided with linearly arranged dots 410 (diameter can be 2.9mm, However, it can be adjusted according to the change of the application conditions), and the distance between the centers of the adjacent dots 410 in this example is 10mm (but it can also be adjusted according to the change of the application conditions). The second part 42 of the sign board 221 is provided with a plurality of lines 420 arranged in parallel, and the distance between the centerlines of the adjacent lines 420 is consistent with the distance between the centers of the adjacent dots 410, which can also be 10mm (but depending on the application The distance D between each corresponding dot 410 and the line 420 is 100mm in this example (but it can also be adjusted according to the changing application conditions). And the first part 41 and the second part 42 of the signage plate 221 are only combined with the design shown in FIG. 2 . In this way, when the central beam of the X beam scattered by the X light source 11 is incident on the knee tibial plateau (Tibial Plateau) 19 of the human body 10 at an angle of θ3 (for example, 10 degrees, but it can be adjusted depending on the application conditions), A pattern as shown in FIGS. 5A and 5B will be formed on the image sensing sheet.

圖5A示出左膝的X光局部示意圖(右膝在此圖被省略)50以及本例相鄰圓點410與相鄰線條420同時在影像感應片上成像的影像示意圖。由圖中可以清楚看出，曝光後的圓點410與線條420間有著是否對準的位置關係，主要是因為X光源11是點光源，其所散射出來的X光束並非互相平行。如圖5B之所示，與膝蓋脛骨平台(Tibial Plateau)19同一水平位置的圓點410與線條420，從兩者是否對準的位置關係(例如是完全對準或是高1公分、低2公分等關係 )將可以解讀出X光束中之中心光束的入射角度的偏差，而能讓X光操作人員即時進行調整。還有，由於X光源11是點光源，其所散射出來的X光束會隨距離而涵蓋更大範圍，因此藉由相鄰多組的圓點410與線條420間位置關係的不同，還可以反推出X光源11與該標示板221間的距離。FIG. 5A shows a partial X-ray schematic diagram of the left knee (the right knee is omitted in this figure) 50 and a schematic diagram of images of adjacent dots 410 and adjacent lines 420 simultaneously formed on the image sensing sheet in this example. It can be clearly seen from the figure that there is an alignment relationship between the exposed dots 410 and the lines 420 , mainly because the X light source 11 is a point light source, and the scattered X beams are not parallel to each other. As shown in Figure 5B, the dot 410 and the line 420 at the same horizontal position as the tibial plateau (Tibial Plateau) 19 of the knee, from the positional relationship of whether the two are aligned (such as being fully aligned or 1 cm high and 2 cm low) centimeters, etc.) will be able to interpret the deviation of the incident angle of the central beam in the X-ray beam, and allow the X-ray operator to make adjustments in real time. In addition, since the X light source 11 is a point light source, the scattered X light beams will cover a larger range with distance, so the positional relationship between the adjacent groups of dots 410 and lines 420 can also be reflected. The distance between the X light source 11 and the signboard 221 is deduced.

另外，上述每個圓點410與線條420可以如圖5A之所示，於其上或其側邊製作有相對應的預設編號(例如圖中所示之10、12、14)或是預設標示((例如多邊形或是具有不同角度位置缺角的圓)來代表其在整體數量(例如32個)中的第幾個，而由完全對準的那一組的編號關係，便可以推估出X光源11所散射出來的X光束中之中心光束的通過位置，進而反推出X光源11的入射角度。In addition, each of the dots 410 and lines 420 above can be shown in FIG. Set the label (such as a polygon or a circle with different angular positions) to represent its number in the overall number (such as 32), and from the numbering relationship of the group that is completely aligned, it can be deduced Estimate the passing position of the central beam in the X beam scattered by the X light source 11 , and then inversely deduce the incident angle of the X light source 11 .

還有，利用與受測者膝蓋脛骨平台(Tibial Plateau)19同一水平位置的圓點410與線條420的編號關係，也可以利用查表或預設的算式來完成受測者身高的反推。進而將受測者身高的資料一併註記到此受測者的膝蓋X光影像圖中。In addition, using the numbering relationship between the dots 410 and the lines 420 at the same horizontal position as the Tibial Plateau 19 of the subject's knee, it is also possible to use a look-up table or a preset formula to complete the inversion of the subject's height. Furthermore, the data of the subject's height are also noted in the subject's knee X-ray image map.

再者，由於X光機有可能會發生故障或是因機件老化而使預設的曝光值不預期地發生飄移，或是操作人士不當操作而導致曝光強度不標準，為此本案係發展出下列功能來解決問題。再請參見圖6，其係本案對於立板22的較佳實施例示意圖，其中標示板221的第二部份42除了設置有平行排列的多個線條420外，還於線條420兩側設有第一參考板61與第二參考板62，該第一參考板61與第二參考板62可以用鋁板來完成，兩個參考板的厚度不同，因此對X光的吸收程度也不同，因此在影像感應片上的成像會有不同的明暗程度，如此便可以反推X光源當次曝光的強度，進而提供曝光強度校正程序的參考。當然第一參考板61與第二參考板62也可以將鋁改成以別的金屬材料或是其他會吸收X光的材料來完成。當然也可以用不同材料但同厚度來分別完成第一參考板61與第二參考板62，或是以同材料且同厚度來分別完成第一參考板61與第二參考板62，但兩者的鏤空圖案不同來造成等效面積的不同。Furthermore, because the X-ray machine may break down or the preset exposure value may drift unexpectedly due to the aging of the machine, or the exposure intensity may not be standard due to improper operation by the operator, this case was developed. The following functions are used to solve the problem. Referring to Fig. 6 again, it is a schematic diagram of a preferred embodiment of the vertical plate 22 in this case, in which the second part 42 of the sign plate 221 is provided with a plurality of lines 420 arranged in parallel, and is also provided with two sides of the line 420. The first reference plate 61 and the second reference plate 62, the first reference plate 61 and the second reference plate 62 can be completed with an aluminum plate, the thickness of the two reference plates is different, so the degree of absorption of X-rays is also different, so in The images on the image sensor sheet will have different degrees of brightness and darkness, so that the intensity of the current exposure of the X-ray source can be deduced, thereby providing a reference for the exposure intensity correction procedure. Of course, the first reference plate 61 and the second reference plate 62 can also be made of other metal materials or other materials that can absorb X-rays. Of course, the first reference plate 61 and the second reference plate 62 can be completed respectively with different materials but with the same thickness, or the first reference plate 61 and the second reference plate 62 can be respectively completed with the same material and the same thickness, but both The different hollowing patterns of different hollowed out parts will cause the difference in equivalent area.

另外，立板主體220本身可以用壓克力或是其他類似工程塑膠的材料來完成，且立板主體220的正面還可設有鏤空處63，用以與壓克力材質來進行曝光強度的差異值比對。當然也可以設有骨骼假體64，也可用以提供曝光強度的參考標準基準值。In addition, the riser body 220 itself can be made of acrylic or other materials similar to engineering plastics, and the front side of the riser body 220 can also be provided with a hollow 63 for adjusting the exposure intensity with the acrylic material. Comparison of difference values. Of course, a skeletal prosthesis 64 may also be provided, which may also be used to provide a reference standard value of the exposure intensity.

綜上所述，本案可以改善習知技術中拍攝角度不易調整與X光影像合格率不高的缺失，確實達成發展本案的主要目的。雖然本發明以實施例揭露如上，但並非用以限定本發明。本發明所屬技術領域中具有通常知識者，在不脫離本發明之技術精神和範圍內，當可作各種之更動與潤飾。因此，本發明之保護範圍當視後附之申請專利範圍請求項所界定者為準。To sum up, this case can improve the lack of difficult adjustment of the shooting angle and the low pass rate of X-ray images in the conventional technology, and indeed achieve the main purpose of developing this case.
