How does dual energy CT work?
In dual-energy CT (DECT), two different x-ray spectra are used to acquire two image datasets of the same region, to allow the analysis of energy-dependent changes in the attenuation of different materials..
What are the advantages of a dual source CT scan?
With Dual Source CT it is possible to double the temporal resolution to 66 ms compared with that of a single source CT, and increase the speed of acquisition while reducing the radiation dose significantly..
What is a dual modality?
In a dual modality model, a single class includes two groups of students.
One group is receiving. in-person instruction while the other group is simultaneously participating in the same lesson by. viewing the instruction online..
What is dual CT scan?
In dual-energy CT (DECT), two different x-ray spectra are used to acquire two image datasets of the same region, to allow the analysis of energy-dependent changes in the attenuation of different materials..
What is dual energy computed tomography?
In dual-energy CT (DECT), two different x-ray spectra are used to acquire two image datasets of the same region, to allow the analysis of energy-dependent changes in the attenuation of different materials..
What is dual modality imaging?
Dual-modality imaging is a technique in which computed tomography (CT) or magnetic resonance imaging is combined with positron emission tomography or single-photon emission CT to acquire structural and functional images with an integated system..
What is dual source CT scan?
A dual source CT (DSCT) is a CT system with two x-ray tubes and two detectors at an angle of approximately 90\xb0.
Both measurement systems acquire CT scan data simultaneously at the same anatomical level of the patient (same z-position)..
What is the modality of computed tomography?
Computed tomography (CT) is a cross sectional x-ray imaging modality.
Cross-sectional images eliminate the problems encountered in radiograph interpretation that are caused by superimposition of the complex anatomy of the skull..
Why is dual energy CT useful?
Dual energy scans can amplify the iodine signal of contrast agents, improving the delineation of arteries.
They can also better distinguish iodine from calcium, therefore allowing better bone subtraction around vessels; for example, at the skull base.
CT of the kidney, ureter and bladder (CT KUB)..
- A Dual-Modal Imaging Method Combining Ultrasound and Electromagnetism for Simultaneous Measurement of Tissue Elasticity and Electrical Conductivity.
- Multimodality imaging, a combination of imaging modalities may provide a better solution to overcome the limitations of the independent techniques.
This approach may provide a large amount of information for each pre-clinical experiment.
