Welcome to this tutorial on Augmented Reality (AR) in surgery! As the title suggests, we will be exploring the role and importance of AR in modern surgical practices.
Goal of the tutorial: The goal is to understand how AR technology is being applied in the medical field, particularly in surgical procedures, and what benefits it brings.
What you will learn: By the end of this tutorial, you will have a clear understanding of AR technology, its applications in surgery, and how to develop a basic AR application that could be used in a surgical context.
Prerequisites: Basic understanding of programming concepts and knowledge of a programming language (preferably Python) would be helpful but not necessary.
AR stands for Augmented Reality. It is a technology that overlays digital information on the real world. In the context of surgery, AR can provide surgeons with real-time information, such as patient data, surgical plans, etc., overlaid on their field of view.
AR in surgery works by using a special display (like AR glasses) that allows surgeons to see the patient and the AR information simultaneously. This information can be 3D models of the patient's anatomy, real-time ultrasound images, or other relevant data.
Developing an AR application involves creating a 3D model, detecting and tracking the real-world object, and overlaying the 3D model on the tracked object.
Since our main focus is understanding the concept, we won't be delving deep into coding. However, here is a basic example of how to create a 3D model using Python's pythreejs library.
# Import the required libraries
from pythreejs import BoxGeometry, Mesh, PerspectiveCamera, Scene, WebGLRenderer, MeshBasicMaterial
# Create a 3D box (which could represent a part of human anatomy)
geometry = BoxGeometry(1, 1, 1) # set the width, height, and depth of the box
material = MeshBasicMaterial(color='red') # set the color of the box
mesh = Mesh(geometry, material) # create the 3D object
# Create a scene and add the 3D object to it
scene = Scene(children=[mesh])
# Set the camera position
camera = PerspectiveCamera(position=[3, 3, 3], fov=20,
children=[DirectionalLight(color='white', position=[3, 5, 1], intensity=0.5)])
# Create and display the renderer
renderer = WebGLRenderer(camera=camera, scene=scene, controls=[OrbitControls(controlling=camera)])
renderer
This will create and display a red 3D box. In a real surgical application, the 3D model would be much more complex and detailed.
In this tutorial, we covered the basics of AR and how it is used in surgery. We also discussed how to create a 3D object using Python. The next step would be to learn how to detect and track real-world objects and overlay the 3D model on them.
Exercise 1: Create a 3D model of a different shape (like a sphere or a cylinder) and display it.
Exercise 2: Change the color and size of the 3D model.
Exercise 3: Learn how to use AR libraries like ARKit or ARCore and create a basic AR application.
Note: These exercises are designed to improve your understanding of AR and programming. There are numerous resources available online to help you with these tasks.
Remember, practice is the key to learning. Happy learning!
