Computed Tomography01:10

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 Imaging
  • Computer-Aided Surgery
  • Orthognathic Surgery

Background:

  • Recent advancements in computer and imaging technology have made 3D imaging protocols feasible for healthcare.
  • The affordability and ease of use of these modalities facilitate their integration into diagnosis and treatment planning.
  • Complex dentofacial deformities require advanced imaging for both functional and esthetic considerations, particularly in orthognathic surgery.

Purpose of the Study:

  • To describe a system utilizing image fusion for patient-specific anatomic reconstruction (PSAR).
  • To demonstrate the application of PSAR in the diagnosis and treatment planning of complex facial deformities.
  • To highlight the benefits of 3D imaging and computer simulation in planning office-based procedures.

Main Methods:

  • Image fusion combines data from different imaging modalities to create a virtual patient record.
  • Patient-specific anatomic reconstruction (PSAR) generates a detailed 3D model of individual anatomy.
  • The described system and its application in a clinical case are presented.

Main Results:

  • Image fusion and PSAR facilitate a more precise analysis of deformities.
  • These techniques aid significantly in diagnosis and the development of treatment plans.
  • The use of PSAR allows for virtual surgical simulation and objective treatment planning.

Conclusions:

  • 3D imaging and computer simulation are effective tools for planning office-based surgical procedures.
  • PSAR enables virtual surgery, leading to definitive and objective treatment plans for facial deformities.
  • The integration of these technologies results in enhanced patient care and cost reduction.
