Scientific visualisation

 Scientific Visualisation In Medical Imaging

What is Scientific Visualisation?

Scientific visualisation focuses on converting scientific data into graphical form. It is used across medicine, engineering, physics, and biology. The goal is to help humans understand complex data by representing it visually.

In medical imaging, scientific visualisation helps to:

• Convert scan data into understandable images

• Remove noise and unwanted artefacts

• Enhance brightness, contrast, and clarity

• Generate 3D/4D interactive models

• Provide simulations for surgical planning

Scientific visualisation works on data coming from CT, MRI, ultrasound, PET, and other imaging devices.

Types of Medical Imaging Techniques

a) X-ray Imaging

• Earliest and simplest imaging technique.

• Uses electromagnetic radiation to capture dense structures like bones.

• Digital X-rays allow image enhancement, zooming, and contrast adjustments.

• Used in detecting fractures, dental issues, chest infections, and bone deformities.

b) Computed Tomography (CT) Scan

• Combines multiple X-ray images taken from different angles.

• A computer processes the slices to form a 3D model.

• Useful for detecting tumors, internal bleeding, stroke, and organ disorders.

• Scientific visualisation helps reconstruct internal organs using volume rendering and multi-planar reconstruction (MPR).

c) Magnetic Resonance Imaging (MRI)

• Uses magnetic fields and radio waves, not radiation.

• Excellent for visualising soft tissues such as the brain, spinal cord, muscles, and joints.

• Provides high-resolution images with detailed internal structures.

• Visualisation tools enhance MRI data for brain mapping, lesion tracking, and surgical planning.

Scientific Visualisation Techniques Used in Medical Imaging

Surface Rendering

Creates 3D surfaces from data.

• Used in 3D printed organs, bone models, and prosthetics.

• Helps in orthopedic surgeries and dental implants.

3D and 4D Visualisation

• 3D = three-dimensional model of organs

• 4D = 3D + time (motion), used for heart imaging and fetalscans
These models allow rotation, zooming, and virtual exploration.

• Surgery and Treatment Planning

• Medical Education
