於此係針對超音波投影系統10之操作進行詳細之描述，請參閱第1圖、第2圖，以及第3圖，第2圖為使用第1圖之超音波投影系統10投影掃描影像24之超音波掃描影像投影方法的流程圖，第3圖為第1圖之超音波探頭18進行超音波掃描所產生之掃描影像24投影在表面22上之簡示圖。如第2圖所示，本發明之超音波掃描方法包含下列步驟。Herein is a detailed description of the operation of the ultrasonic projection system 10, see FIG. 1, FIG. 2, and FIG. 3, and FIG. 2 is a projection of the scanned image 24 using the ultrasonic projection system 10 of FIG. A flowchart of a method for projecting an ultrasonic scanned image, and FIG. 3 is a schematic diagram of a scanned image 24 generated by the ultrasonic probe 18 of FIG. 1 projected onto the surface 22. As shown in Fig. 2, the ultrasonic scanning method of the present invention comprises the following steps.
步驟200：使用超音波探頭18於表面22上進行掃描並產生掃描影像24；步驟202：影像擷取裝置12擷取包含超音波探頭18與表面22之參考影像；步驟204：處理單元20根據超音波探頭18在參考影像中之位置，在參考影像中對應表面22之位置上定義出複數個可投影區域26；步驟206：處理單元20將其中之一可投影區域26設定為實際投影區域；步驟208：投影單元裝置16投射掃描影像24至表面22的實際投影區域之位置上。Step 200: Scanning on the surface 22 using the ultrasonic probe 18 and generating a scanned image 24; Step 202: The image capturing device 12 captures a reference image including the ultrasonic probe 18 and the surface 22; Step 204: The processing unit 20 is based on the super The position of the sound wave probe 18 in the reference image defines a plurality of projectable regions 26 at the position of the corresponding surface 22 in the reference image; step 206: the processing unit 20 sets one of the projectable regions 26 as the actual projected region; 208: The projection unit device 16 projects the scanned image 24 to the position of the actual projection area of the surface 22.
以下係就上述步驟進行說明。首先，在步驟200中，使用者(如醫療人員等)係可將使超音波探頭18移動到表面22上之感興趣區域(例如病患身體上之特定檢測區域等)以進行超音波掃描而產生相對應之掃描影像24。接下來，影像擷取裝置12可擷取包含超音波探頭18與表面22之參考影像(步驟202)，以供處理單元20可使用常見之影像處理方法而據以判斷出超音波探頭18在影像擷取裝置12所擷取之參考影像中之位置，舉例來說，在此實施例中，如第3圖所示，超音波探頭18上可形成有定位標記19，藉此，處理單元20即可利用擷取出定位標記19在參考影像中之位置的影像處理方式來計算出超音波探頭18在參考影像中之位置。The following steps are explained below. First, in step 200, a user (eg, a medical professional, etc.) can move the ultrasound probe 18 to a region of interest on the surface 22 (eg, a particular detection region on the patient's body, etc.) for ultrasound scanning. A corresponding scanned image 24 is generated. Next, the image capturing device 12 can capture the reference image including the ultrasonic probe 18 and the surface 22 (step 202), so that the processing unit 20 can determine the ultrasonic probe 18 in the image by using a common image processing method. The position in the reference image captured by the capture device 12, for example, in this embodiment, as shown in FIG. 3, the positioning probe 19 may be formed on the ultrasonic probe 18, whereby the processing unit 20 The position of the ultrasonic probe 18 in the reference image can be calculated by the image processing of the position of the position marker 19 in the reference image.
在完成上述定位超音波探頭18之步驟後，處理單元20即可根據超音波探頭18在影像擷取裝置12所擷取之參考影像中之位置，在參考影像中對應表面22之位置上定義出複數個可投影區域26(步驟204)，也就是說，由第3圖可知，處理單元20係可將表面22對應超音波探頭18之區域(例如表面22上被超音波探頭18所遮住之區域)定義為不可投影區域28，且將表面22除對應超音波探頭18之區域之外的區域定義為可投影區域26以確保投影裝置16將掃描影像24投影在超音波探頭18之周圍而方便使用者觀看。After the step of positioning the ultrasonic probe 18 is completed, the processing unit 20 can define the position of the corresponding surface 22 in the reference image according to the position of the ultrasonic probe 18 in the reference image captured by the image capturing device 12. A plurality of projectable regions 26 (step 204), that is, as can be seen from FIG. 3, the processing unit 20 can correspond the surface 22 to the region of the ultrasonic probe 18 (eg,The area of the surface 22 that is covered by the ultrasonic probe 18 is defined as the unprojectable area 28, and the area of the surface 22 other than the area corresponding to the ultrasonic probe 18 is defined as the projectable area 26 to ensure that the projection device 16 will scan. The image 24 is projected around the ultrasonic probe 18 for user convenience.
接下來，處理單元20係可進行將其中之一可投影區域26設定為可供投影裝置16進行投影之實際投影區域(步驟206)，在此實施例中，處理單元20係可採用自動判斷之方式以將如第3圖所示之其中之一可投影區域26設定為實際投影區域，更詳細地說，處理單元20可針對每一可投影區域26分別計算出相對應之區域影像均勻度(如灰階平均值或亮度均勻值等)，並接著針對每一可投影區域26分別計算出相對應之區域影像均勻度以進行比對，且根據每一可投影區域26之區域影像均勻度之比對結果，將符合比對結果之其中之一可投影區域26設定為實際投影區域，舉例來說，假設處理單元20判斷出如第3圖所示之位於左下角之可投影區域26之區域影像均勻度大於預設之系統判斷值，此即代表位於左下角之可投影區域26係可視為表面22上之平整區域，如此一來，處理單元20即可將位於左下角之可投影區域26設定為實際投影區域。Next, the processing unit 20 can perform an actual projection area in which one of the projectable regions 26 is set to be projected by the projection device 16 (step 206). In this embodiment, the processing unit 20 can automatically determine In a manner, one of the projectable regions 26 as shown in FIG. 3 is set as the actual projected region. In more detail, the processing unit 20 can calculate the corresponding region image uniformity for each of the projectable regions 26 ( Such as grayscale average or brightness uniformity, etc.), and then calculate the corresponding regional image uniformity for each of the projectable regions 26 for comparison, and according to the regional image uniformity of each of the projectable regions 26 As a result of the comparison, one of the comparable projection results 26 is set as the actual projection area. For example, it is assumed that the processing unit 20 determines the area of the projectable area 26 located at the lower left corner as shown in FIG. The image uniformity is greater than the preset system judgment value, which means that the projectable area 26 located in the lower left corner can be regarded as a flat area on the surface 22, so that the processing unit 20 can be positioned. The lower left corner of the projection area 26 may be set as the actual projection area.
需注意的是，處理單元20所採用之區域影像均勻度比對方式可不限於上述實施例，舉例來說，若是處理單元20判斷出如第3圖所示之每一可投影區域26之區域影像均勻度均小於上述系統判斷值，但位於左下角之可投影區域26之區域影像均勻度大於其餘可投影區域26之區域影像均勻度，此即代表如第3圖所示之位於左下角之可投影區域26係為表面22上相對較為平整之區域，因此，處理單元20就會將位於左下角之可投影區域26設定為實際投影區域。換句話說，只要是比對每一可投影區域26之區域影像均勻度之判斷設計，其均可為本發明所採用之。It should be noted that the area image uniformity comparison mode adopted by the processing unit 20 is not limited to the above embodiment. For example, if the processing unit 20 determines the area image of each of the projectable areas 26 as shown in FIG. The uniformity is smaller than the above-mentioned system judgment value, but the area image uniformity of the projectable area 26 located in the lower left corner is greater than the area image uniformity of the remaining projectable area 26, which means that it is located in the lower left corner as shown in FIG. The projection area 26 is a relatively flat area on the surface 22, so the processing unit 20 sets the projectable area 26 at the lower left corner as the actual projection area. In other words, as long as it is a judgment design that compares the uniformity of the image of each of the projectable regions 26, it can be employed in the present invention.
此外，處理單元20係可改採用將每一可投影區域26之區域影像均勻度與上述系統判斷值與使用者設定值之乘積進行比對之方式來調整將可投影區域26設定為實際投影區域之變更頻率，其中使用者設定值係可較佳地介於0與1之間。在實際應用中，當使用者設定值設定為0時，此即代表處理單元20只會將目前符合比對結果(即可投影區域26之區域影像均勻度大於系統判斷值與使用者設定值之乘積)的可投影區域26設定為實際投影區域，但不會隨著表面22之影像均勻度的變化(例如病患身體表面之影像均勻度會隨著病患的呼吸行為而出現變化等)而變更實際投影區域之設定，藉以防止因實際投影區域不斷地變換而造成使用者在觀看掃描影像上的困擾。另一方面，當使用者設定值設定為1時，此即代表處理單元20會將目前其區域影像均勻度符合上述比對結果的可投影區域26設定為實際投影區域，並且會隨著表面22之影像均勻度的變化而不斷地變更實際投影區域之設定，舉例來說，當原本符合上述比對結果的可投影區域26隨著表面22之影像均勻度的變化而導致其區域影像均勻度小於系統判斷值與使用者設定值之乘積時，處理單元20就會改將隨著表面22之影像均勻度的變化而導致其區域影像均勻度大於系統判斷值與使用者設定值之乘積的另一可投影區域26設定為實際投影區域，藉以確保投影裝置16在使用者操作超音波探頭18進行超音波掃描的過程中可將掃描影像24投影在表面22之平整區域上，從而讓使用者可以觀看到清楚的掃描影像24。In addition, the processing unit 20 can adjust the area of the image area uniformity of each of the projectable areas 26 to the product of the system determination value and the user setting value to adjust the projectable area 26 to the actual projection area. The frequency of change, wherein the user setting value is preferably between 0 and 1. In practical applications, when the user setting value is set to 0, this means that the processing unit 20 only matches the current matching result (that is, the uniformity of the area of the projected area 26 is greater than the system judgment value and the user setting value. The projectable area 26 of the product is set as the actual projection area, but does not change with the uniformity of the image of the surface 22 (for example, the image uniformity of the patient's body surface changes with the patient's breathing behavior, etc.) The setting of the actual projection area is changed to prevent the user from being troubled by viewing the scanned image due to the continuous change of the actual projection area. On the other hand, when the user setting value is set to 1, this means that the processing unit 20 sets the currently projectable area 26 whose area image uniformity conforms to the above comparison result as the actual projection area, and will follow the surface 22 The change of the image uniformity continuously changes the setting of the actual projection area. For example, when the projection area 26 that originally meets the above comparison result changes with the image uniformity of the surface 22, the uniformity of the area image is smaller than When the system determines the product of the value and the user setting value, the processing unit 20 changes the image uniformity of the surface 22 to be larger than the product of the system judgment value and the user setting value. The projectable area 26 is set as the actual projected area, thereby ensuring that the projection device 16 can project the scanned image 24 on the flat area of the surface 22 during the user's operation of the ultrasonic probe 18 for ultrasonic scanning, thereby allowing the user to view Go to the clear scanned image 24.
最後，只要投影裝置16根據上述步驟所設定好之實際投影區域以投射掃描影像24至表面22的實際投影區域之位置上(步驟208)，如此即可允許使用者在使用超音波探頭18於表面22上進行超音波掃描的過程中能夠同時在表面22觀看到投影在超音波探頭18之周圍的掃描影像24，從而大幅地提升超音波投影系統10在實際操作上的便利性，且有效地解決先前技術中所提到的需一邊移動超音波探頭且一邊轉頭觀看超音波掃描影像的操作容易造成使用者在超音波檢測診斷上的誤判的問題。另外，在表面22所呈現的顏色不適合投影的情況下(例如病患身體膚色過黑等)，超音波投影系統10可另採用影像擷取裝置12朝表面22擷取判斷影像之方式，以使處理單元20可根據影像擷取裝置12所擷取之判斷影像中之表面22的實際投影區域之位置的一身體膚色，控制投影裝置16調整掃描影像24之投影顯示，例如調高掃描影像24之投影亮度等，藉以使掃描影像24在表面22上之投影顯示能夠更加清楚以便使用者觀看。Finally, as long as the projection device 16 is based on the actual projection area set by the above steps to project the scanned image 24 to the position of the actual projection area of the surface 22 (step 208), thus allowing the user to use the ultrasonic probe 18 on the surface. During the ultrasonic scanning on 22, the scanned image 24 projected around the ultrasonic probe 18 can be simultaneously viewed on the surface 22, thereby greatly improving the convenience of the ultrasonic projection system 10 in practical operation, and effectively solving the problem. As mentioned in the prior art, it is easy to move the ultrasonic probe while turning the head to view the ultrasonic scanned image.Causes the user to misjudge the diagnosis of ultrasonic sound. In addition, in the case that the color presented by the surface 22 is not suitable for projection (for example, the skin color of the patient's body is too dark, etc.), the ultrasonic projection system 10 can additionally use the image capturing device 12 to capture the image of the image toward the surface 22, so that The processing unit 20 can control the projection device 16 to adjust the projection display of the scanned image 24 according to a body color of the position of the actual projection area of the surface 22 in the image captured by the image capturing device 12, for example, to increase the scanned image 24 The brightness or the like is projected so that the projected display of the scanned image 24 on the surface 22 can be made clearer for the user to view.
值得一提的是，本發明將其中之一可投影區域26設定為實際投影區域之設計係可不限於上述實施例，其亦可改採用超音波掃描裝置14提供可投影區域選擇介面以供使用者手動選擇之設計，更詳細地說，在另一實施例中，在處理單元20在參考影像中對應表面22之位置上定義出複數個可投影區域26後，投影裝置16係可將對應複數個可投影區域26之可投影區域選擇介面投影至表面22上，並且影像擷取裝置12係可朝表面22擷取判斷影像，藉此，處理單元20即可根據判斷影像產生可投影區域選擇介面之選擇結果，且根據選擇結果相對應地將其中之一可投影區域26設定為實際投影區域，舉例來說，若是處理單元20判斷出判斷影像中具有手勢影像(例如使用者之手指指向其中之一可投影區域26)，則處理單元20即可將手勢影像所指示之其中之一可投影區域26設定為實際投影區域，可投影區域選擇介面可另外包含即時波形、量測結果、使用參數等，供使用者操作的參考。It should be noted that the design of one of the projectable regions 26 as the actual projection region may not be limited to the above embodiment, and the ultrasonic scanning device 14 may be used to provide a projectable region selection interface for the user. The design of the manual selection, in more detail, in another embodiment, after the processing unit 20 defines a plurality of projectable regions 26 at the position of the corresponding surface 22 in the reference image, the projection device 16 can correspond to a plurality of The projectable area selection interface of the projectable area 26 is projected onto the surface 22, and the image capturing device 12 can capture the determination image toward the surface 22, whereby the processing unit 20 can generate the projectable area selection interface according to the determination image. Selecting a result, and correspondingly setting one of the projectable regions 26 as an actual projection region according to the selection result, for example, if the processing unit 20 determines that the image has a gesture image (for example, the user's finger points to one of them) The projectable area 26), the processing unit 20 can set one of the projectable regions 26 indicated by the gesture image as the actual projection area. The projectable area selection interface may additionally include an instant waveform, a measurement result, a usage parameter, etc., for reference by the user.
除此之外，在另一實施例中，超音波掃描裝置14可改採用以螢幕顯示之方式來提供可投影區域選擇介面，而使用者則是可按壓超音波探頭18上相對應的選擇按鍵或是以直接在螢幕上點選之方式來進行將其中之一可投影區域26設定為實際投影區域之操作，但不受此限，換句話說，只要是使用可投影區域選擇介面以供使用者手動設定實際投影區域之設計，其均可為本發明所採用之。In addition, in another embodiment, the ultrasonic scanning device 14 can be used to provide a projectable area selection interface in a screen display manner, and the user can press the corresponding selection button on the ultrasonic probe 18. Or, the operation of setting one of the projectable regions 26 as the actual projection region by directly clicking on the screen, but not limited thereto, in other words, using the projectable region selection interface for use. Manually set the actual projection area design, which can beThe invention was adopted.
相較於先前技術，本發明係採用將超音波探頭所產生之掃描影像經由投影裝置直接投影至表面上之設計，以允許使用者在使用超音波探頭於表面上進行超音波掃描的過程中能夠同時在表面觀看到投影在超音波探頭之周圍的掃描影像，如此一來，本發明不僅可大幅地提升超音波投影系統在實際操作上的便利性，同時亦可有效地解決先前技術中所提到的需一邊移動超音波探頭且一邊轉頭觀看顯示螢幕更方便的問題，從而讓使用者能夠做出更加準確的超音波檢測診斷。Compared with the prior art, the present invention adopts a design that directly projects a scanned image generated by an ultrasonic probe onto a surface via a projection device, thereby allowing a user to perform ultrasonic scanning on the surface using an ultrasonic probe.
