In an existing work15, X-ray and CT scans are examined to locate the catheter in the heart. However, AR TAVR replacement establishes a new possibility in TAVR18 surgical procedure by the implementation of an automated model using 3D reconstruction. As mentioned in the protocol section this work has five stages to design. The first stage of DITF22, mentioned in section 6, which we proposed in our previous work22, is enhanced in...

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.

Automatic Surgery in Transcatheter Aortic Valve Replacement Using Augmented Reality

Our research focuses on revolutionizing remote surgery through augmented reality and robotics, aiming to enhance precision and accessibility in medical procedures. We are exploring how real-time 3D reconstruction and feature extraction can provide surgeons with unprecedented control and visualization, even from a distance. We have implemented our own directional intensified feature extraction to ensure precise and accurate detection of surgical features, enhancing the surgeon's control over the robotic arm.By using 3D reconstruction from minimal 2D images, we have significantly reduced the hardware complexity and improved the efficiency of our system. Our system provides the best surveillance of the surgical environment using a single mobile camera synchronized to take snaps every two seconds, ensuring real-time updates for the remote surgeon. We have developed seamless communication protocols with low latency and high reliability using Bluetooth and LAN, ensuring uninterrupted and accurate data transmission.Our approach to achieve precise, real-time synchronization between video feeds and robotic arm responses can serve as a benchmark for future research in remote surgery and telemedicine. It offers a model for integrating real-time data with robotic control systems.

The protocol was tested with the heart phantom model. Figure 2 shows the expected setup for the live surveillance of the surgical field with the help of spatially distributed cameras. The distributed cameras, as shown in Figure 2, help to increase the spatial resolution of the field for effective 3D reconstruction. However, realizing the physical placement of those cameras in various spatial locations involves complexity. So, we have optimized the setup design a...
