Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Area of Science:

Medical Visualization
Surgical Planning
Collaborative Systems

Context:

Complex surgeries require multi-disciplinary collaboration for synthesized operation plans.
Current systems lack distributed collaboration environments for remote surgical teams.
Accurate and intuitive operation planning is crucial for complex procedures.

Purpose:

To implement a networked platform for collaborative 3D surgical planning.
To enable real-time, distributed collaboration among surgeons at different locations.
To develop a foundation for collaborative surgery simulation and prosthesis design software.

Summary:

A Client/Server platform was developed using VTK and HOOPS/3DAF for 3D model reconstruction from DICOM CT data.
The system reconstructs 3D models, simplifies mesh data, and transmits it in a lossless HSF format over the network.
A HOOPS/NET-based collaborative interactive visualization system was implemented, demonstrating clear 3D models and real-time interaction.

Impact:

Provides a novel distributed collaboration environment for surgical teams.
Enhances the accuracy and intuitiveness of surgical operation planning.
Facilitates the development of advanced collaborative surgery simulation and prosthesis design tools.
