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...

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

Radiation: Applications

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Cancer Therapies

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Imaging Studies III: Computed Tomography

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...

Background:

Helical tomotherapy integrates linear accelerator (linac) technology with on-board imaging and Intensity-Modulated Radiation Therapy (IMRT) capabilities.
This innovative device aims to improve precision and efficacy in cancer treatment delivery.
The National Institut of Cancer (INCa) in France has supported initial national evaluations of this technology.

Purpose of the Study:

To present the first national French evaluations of helical tomotherapy.
To assess the dosimetric characteristics of helical tomotherapy for Intensity-Modulated Radiation Therapy (IMRT) treatments.
To evaluate its suitability for treating large and complex tumor volumes while sparing organs at risk.

Main Methods:

Evaluation of helical tomotherapy's dosimetric properties, focusing on target volume homogeneity.
Assessment of the device's ability to limit radiation dose outside of target volumes.
Conducting comparative dosimetric studies to benchmark performance.

Main Results:

Helical tomotherapy demonstrates high quality of dose homogeneity within target volumes.
Effective dose cut-off outside target volumes ensures minimal irradiation of healthy tissues.
The technology allows for Intensity-Modulated Radiation Therapy (IMRT) treatments for large and complex anatomical sites.

Conclusions:

Helical tomotherapy facilitates Intensity-Modulated Radiation Therapy (IMRT) for challenging cancer cases.
The device provides excellent organ at risk sparing, crucial for minimizing treatment side effects.
Initial French evaluations support the clinical utility of helical tomotherapy in radiation oncology.
