Summary
A new flat panel volume computed tomography (FP-VCT) offers very high resolution for detailed imaging. This advanced CT technology shows promise for early tumor assessment, perfusion mapping, and intricate skeletal analysis.
Area of Science:
- Medical Imaging
- Radiology
- Computed Tomography
Background:
- Computed tomography (CT) is a cornerstone of medical imaging.
- Advancements in CT technology aim to improve spatial resolution and diagnostic capabilities.
Purpose of the Study:
- To evaluate a novel flat panel volume computed tomography (FP-VCT) system.
- Assess its very high isotropic spatial resolution and Z-axis coverage.
Main Methods:
- Utilized a prototype FP-VCT scanner with a 0.2 mm detector cell size.
- Conducted phantom studies, specimen examinations, and animal research.
Main Results:
- Enabled accurate solid tumor volume determination for early therapeutic response assessment.
- Facilitated whole-body perfusion mapping in mice and improved coronary artery plaque classification.

01:10Computed 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...

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...
01:29Positron 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...

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
