AR, 3B modeli gerçek dünya ortamında üst üste bindirebilir. AR'ye yönelik teknolojik gelişme, eğitim1, tıp2, üretim3 ve eğlence4 olmak üzere birçok alanda paradigma kayması yarattı. AR teknolojisi, ultra güvenilir düşük gecikmeli iletişim ile birlikte, tıp alanındaki kaçınılmaz rolünü kanıtlıyor. İnsan anatomisinin öğrenme aşamasından cerrahi rehberliğe kadar, öğrenme aşamaları AR destekli yazılım 5,6 ve donanım ile görselleştirilebilir. AR, cerrahi bir ortamda tıp doktoruna çok önemli ve güvenilir bir çözüm sunar 7,8.
Aort kapak darlığı, insanoğlunda en sık görülen kalp kapak hastalığıdır9. Hastalığın temel nedeni, kötü beslenme alışkanlıkları ve günlük yaşamın düzensiz rutinleridir. Hastalığın belirtisi ve sonucu kalp kapakçığının daralması ve ardından kan akışının azalmasıdır. İnsan kalbinde herhangi bir hasar meydana gelmeden önce bu sorunun ele alınması gerekir. Böylece, kalp kan akışını işlemek için aşırı yüklenir. Bu nedenle, herhangi bir hasar meydana gelmeden önce, son günlerdeki teknolojik gelişmeler nedeniyle TAVR prosedürü kullanılarak da yapılabilen ameliyatın yapılması gerekir. Prosedür, kalbin ve hastaların diğer vücut bölümlerinin durumuna göre benimsenebilir. Bu TAVR 10,11'de, kalpteki hasarlı kapağın yerini almak için kateter yerleştirilir. Bununla birlikte, valfi değiştirmek için kateter pozisyonunu12 yerleştirmek uygulayıcı için sıkıcıdır. Bu fikir bizi, cerrahın değiştirme işlemi sırasında kapağı hassas bir şekilde konumlandırmasına yardımcı olan AR 13,14'e dayalı otomatik bir cerrahi modeli tasarlamaya motive etti. Ayrıca ameliyat, cerrahın uzak bir konumdan yakalanan hareketini robotik kola eşleyen bir hareket haritalama algoritması ile gerçekleştirilebilir.
Mevcut çalışma 15,16,17'de, TAVR18 prosedürünün görselleştirilmesi floroskopi ile izlenmektedir. Bu nedenle, kalp kapakçığını analiz etmek zordur ve değiştirme yerini bulmak sıkıcıdır. Bu, kateterin insan kalbine yerleştirilmesi için bir engel oluşturur. Ek olarak, süreci otomatik hale getirmek için uzak hareket cerrahi alanla eşleştirilir. Bununla birlikte, araştırma boşluğunun üstesinden gelmek için, AR destekli teknolojiyi kullanarak valf değişimi için otomatik robotik tabanlı bir ameliyat öneriyoruz.
Protokol tüm cerrahi ortamlara uygulanabilen jenerik bir modeldir. Çalışmanın başlangıç aşamasında, 2D görüntüler, en büyük serbestlik derecesinin en yüksek uzamsal çözünürlüğü ile cerrahi ortamın her yerinde yakalanır. Bu, 3D rekonstrüksiyon19 amacı için yeterli görüntünün yakalandığı ve ardından el hareketi izleme20 yoluyla hareket haritalamanın yapıldığı anlamına gelir.

automatic surgery in transcatheter aortic valve replacement using augmented reality

Artırılmış Gerçeklik (AR), tıbbi uygulamalarda yüksek talep görmektedir. Bu makalenin amacı, Transkateter Aort Kapak Replasmanı (TAVR) için AR kullanarak otomatik cerrahi sağlamaktır. TAVR, açık kalp cerrahisi için alternatif tıbbi prosedürdür. TAVR, bir kateter kullanarak yaralı kapağı yenisiyle değiştirir. Mevcut modelde uzaktan yönlendirme yapılırken, ameliyat AR'ye dayalı olarak otomatikleştirilmemektedir. Bu makalede, cerrahi ortamda görüntü yakalamanın otomasyonu için bir motora bağlı, uzamsal olarak hizalanmış bir kamera kullandık. Kamera, kateter test yatağı ile birlikte hastanın kalbinin 2D yüksek çözünürlüklü görüntüsünü izler. Yakalanan bu görüntüler, mobil uygulama kullanılarak kardiyoloji uzmanı olan uzaktaki bir cerraha yüklenir. Bu görüntü, 2D görüntü izlemeden 3D rekonstrüksiyon için kullanılır. Bu, bir dizüstü bilgisayardaki öykünücü gibi bir HoloLens görüntülenir. Cerrah, döndürme ve ölçekleme gibi ek dönüştürme özellikleriyle yeniden yapılandırılmış 3D görüntüleri uzaktan inceleyebilir. Bu dönüştürme özellikleri el hareketleriyle etkinleştirilir. Cerrahın rehberliği, süreci gerçek zamanlı senaryolarda otomatikleştirmek için cerrahi ortama iletilir. Cerrahi alandaki kateter test yatağı, uzaktaki cerrahın el hareketi rehberliği ile kontrol edilir. Geliştirilen prototip model, AR aracılığıyla uzaktan cerrahi rehberliğin etkinliğini göstermektedir.

AR can superimpose the 3D model in a real-world environment. The technological development towards AR has made a paradigm shift in many fields, namely education1, medical2, manufacturing3, and entertainment4. AR technology, along with ultra-reliable low-latency communication, proves its inevitable role in the medical field. From the learning stage of human anatomy to surgical guidance, the stages of learning can be visualized with AR-powered software5,6 and hardware. AR provides a crucial and reliable solution to the medical practitioner in a surgical environment7,8.
Aortic valve stenosis is the heart valve disease, which is most common among mankind9. The root cause of the disease is poor food habits and irregular routines of day-to-day life. The symptom and result of the disease is the narrowing of the heart valve, followed by a reduction in the blood flow. This problem needs to be addressed before any damage takes place to the human heart. Thus, the heart is overburdened to process the blood flow. So, before any damage happens, surgery needs to be done, which, owing to technological developments in recent days, can also be done using the TAVR procedure. The procedure can be adopted based on the condition of the heart and other body parts of patients. In this TAVR10,11, the catheter is inserted to replace the damaged valve in the heart. However, placing the catheter position12 to replace the valve is tedious for the practitioner. This idea motivated us to design an automated surgery model based on AR13,14, which helps the surgeon to precisely position the valve during the replacement process. Moreover, the surgery can be performed by a motion mapping algorithm, which maps the surgeon&#39;s movement captured from a remote location to the robotic arm.
In the existing work15,16,17, the visualization of the TAVR18 procedure is monitored through fluoroscopy. Hence, it is difficult to analyze the heart valve and tedious to find the replacement location. This sets up a barrier to positioning the catheter in the human heart. In addition, the remote motion is mapped to the surgical field to make the process automated. However, to overcome the research gap, we propose an automated robotic-based surgery for valve replacement using AR-assisted technology.
The protocol is a generic model that can be applied to all surgical environments. In the beginning stage of the work, 2D images are captured all around the surgical environment with the fullest spatial resolution of the largest degree of freedom. This means that enough images are captured for 3D reconstruction19 purpose, followed by motion mapping through hand gesture tracking20.

Automatic Surgery in Transcatheter Aortic Valve Replacement Using Augmented Reality

Augmented Reality (AR) is in high demand in medical applications. The aim of the paper is to provide automatic surgery using AR for the Transcatheter Aortic Valve Replacement (TAVR). TAVR is the alternate medical procedure for open-heart surgery. TAVR replaces the injured valve with the new one using a catheter. In the existing model, remote guidance is given, while the surgery is not automated based on AR. In this article, we deployed a spatially aligned camera that is connected to a motor for the automation of image capture in the surgical environment. The camera tracks the 2D high-resolution image of the patient's heart along with the catheter testbed. These captured images are uploaded using the mobile app to a remote surgeon who is a cardiology expert. This image is utilized for the 3D reconstruction from 2D image tracking. This is viewed in a HoloLens like an emulator in a laptop. The surgeon can remotely inspect the 3D reconstructed images with additional transformation features such as rotation and scaling. These transformation features are enabled through hand gestures. The surgeon's guidance is transmitted to the surgical environment to automate the process in real-time scenarios. The catheter testbed in the surgical field is controlled by the hand gesture guidance of the remote surgeon. The developed prototype model demonstrates the effectiveness of remote surgical guidance through AR.

This article presents the design and implementation of an automatic surgery module based on augmented reality (AR)- based 3D reconstruction. The system enables remote surgery by allowing surgeons to inspect reconstructed features and replicate surgical hand movements as if they were performing the surgery in close proximity.

Let the client module include a robotic arm designed to have rotational movement in its base, shoulder, elbow, wrist, and fingers.Ensure that MG996R servos are used to govern the rotational movement at the base, shoulder, and elbow. Use the SG90 servo motor to control the rotational movement at the wrist and fingers. Compile the code given in the microcontroller integrated development environment to drive the robotic arm based on the commands received from the remote surgeon.Read two images at a time in a sequence, one by one, from the local folder to identify the possible overlapping between them. Extract the features using the DITF method. Reconstruct three-dimensional images from the collected features using SFM.Enable the surgeon to inspect the three-dimensional reconstructed image features using hand gesture controls for rotation and zoom in or out, allowing visualization from all perspectives. Normalize and map the distance between the tip of the surgeon's thumb and the index finger of the right hand into a corresponding angle of rotation. Transmit the hand gesture control through Bluetooth to the remote surgery environment.Ensure that the rotation of the object platter at the remote site mirrors the rotation of the three-dimensional reconstructed features at the surgeon's end. The accuracy of motion mapping decreased as the distance between two fingers increased. The DITF algorithm achieved the lowest latency compared to ORB and BEBLID.
