Review Questions

• How does terahertz imaging enhance the diagnosis of medical conditions compared to traditional imaging techniques?
  • Terahertz imaging enhances medical diagnosis by providing non-invasive and real-time observations of biological tissues without exposing patients to ionizing radiation. Unlike traditional techniques such as X-ray or MRI, terahertz imaging can effectively detect cancerous tissues at an earlier stage due to its unique interaction with water molecules and other biological substances. This results in improved accuracy in identifying anomalies and allows for better treatment planning.
• Discuss the advantages of using terahertz computed tomography over conventional CT in biomedical applications.
  • Terahertz computed tomography offers several advantages over conventional CT methods. It utilizes non-ionizing radiation, significantly reducing the risk associated with radiation exposure for patients. Additionally, terahertz CT can provide high-resolution images with better contrast for soft tissues, which are often challenging to visualize with traditional X-rays. This improved capability enhances the accuracy of disease detection and monitoring, leading to more effective patient care.
• Evaluate the impact of terahertz near-field imaging on the future of biomedical research and diagnostics.
  • Terahertz near-field imaging is set to revolutionize biomedical research and diagnostics by enabling unprecedented resolution and detail in imaging biological samples. This technique allows scientists to observe cellular structures and processes at a microscopic level, which is essential for understanding disease mechanisms and developing targeted therapies. The ability to analyze molecular composition through terahertz interactions will further enhance diagnostics, paving the way for personalized medicine approaches that tailor treatments based on individual molecular profiles.
