Area of Science:
- Oncology
- Medical Physics
- Radiotherapy Technology
Background:
- Image-guided radiation therapy (IGRT) utilization is expanding for treating thoracic and abdominal malignancies.
- Accurate tumor targeting is crucial for effective radiation delivery and minimizing off-target toxicity.
Purpose of the Study:
- To review the fundamental processes involved in image-guided radiation therapy.
- To describe optimal techniques for fiducial marker implantation in the context of IGRT.
Main Methods:
- Literature review of current IGRT practices.
- Analysis of fiducial marker implantation strategies for thoracic and abdominal tumors.
Main Results:
- IGRT enhances precision in radiation delivery for challenging tumor sites.
- Specific techniques ensure accurate and stable fiducial marker placement, critical for real-time tumor tracking.
Conclusions:
- IGRT is a vital tool for modern radiation oncology, particularly for thoracic and abdominal cancers.
- Mastery of fiducial marker implantation techniques is essential for maximizing the benefits of IGRT.

01:20Imaging Studies for Cardiovascular System III: X-Ray
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
