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...

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...

Background:

Patient positioning accuracy is critical for high-precision radiotherapy, particularly spine stereotactic body radiotherapy (SBRT).
Real-time monitoring of patient position is essential to minimize radiation dose to healthy tissues and maximize tumor targeting accuracy.

Purpose of the Study:

To evaluate the efficacy of combining digital tomosynthesis (DTS) and triangulation for precise spine position detection.
To assess the system's precision and latency in determining 3D patient position during simulated SBRT conditions.

Main Methods:

Utilized non-clinical DTS software and an anthropomorphic pelvic phantom with a bone-like spine.
Generated single-slice DTS images from kilovoltage cone beam CT projection data (2-16° gantry rotation).
Registered DTS slices to digitally reconstructed DTS from planning CT scans for 2D shift determination and triangulated multiple DTS registrations for 3D position calculation.

Main Results:

The combined DTS and triangulation system demonstrated precise 3D phantom position determination with updates possible every degree.
Investigated the impact of DTS and triangulation angles on position determination precision.
Assessed the system's ability to detect various sudden and gradual patient movements during kilovoltage image acquisition, simulating SBRT scenarios.

Conclusions:

The DTS and triangulation combination offers a promising solution for accurate and timely spine position monitoring in SBRT.
The system's ability to detect patient movement in real-time can significantly improve treatment safety and efficacy.
Further validation in clinical settings is warranted to confirm its utility in patient treatment.
