Cardiac computed tomography CT systems use a series of X-ray images to create an image volume dataset that can be sliced or manipulated on any plane using advanced visualization software. This channel includes
This approach offers distinct advantages in cases of incomplete and noisy data than analytic reconstruction, and especially suitable for phase-contrast interior tomography by incorporating prior knowledge in a region of interest (ROI). Biological experiments demonstrate the merits of the proposed approach....
A 5-month-old baby, suffering from severe hypertension, was presented to the hospital. Ultrasound examination showed bilateral congenital hydronephrosis. A contrast CT scan was performed with a dual source photon-counting detector CT, NAEOTOM Alpha.Pro, to rule out renovascular etiology of the hyper...
Computed Tomographic Angiography (CTA) usescomputerized tomographywith intravenous administration of a radio-contrast agent to visualize blood vessels. With the advent of multi-detector row CTangiography, this test offers high spatial resolution images of vessels.21It provides a more detailed overview of...
mm and interval of 3 mm forsoft tissue. If lesions are located in surgically inaccessible locations, a fine needle aspirate can be obtained with an appropriate needle, which is inserted into the skin and advanced under subsequent computed tomography guidance (scan, advance, scan) to the lesion....
A computed tomography (CT) scan is a noninvasive diagnostic test that uses x-rays and a computer to create images of the body. It allows your doctor to view your spine or brain in slices, as if it were sliced layer-by-layer and a picture taken of each slice. This test can help ...
While microfocus X-ray computed tomography (microCT) could be appropriate, many microcarriers are hydrated before in-vitro use. This wet state makes them swell, changing considerably their morphology and making them indistinguishable from the culture solution in regular microCT images due to their ...
Computed Tomography 10.0 INTRODUCTION Computed tomography (CT) has experienced enormous growth in clinical use over the past three decades primarily due to significant advances in image quality and a dramatic reduction in acquisition time as the technolo
A phase-contrast x-ray computed tomography scanner, a monochromatic diffraction computed tomography scanner, a rotatable monochromatic diffraction computed tomography scanner, and a combination phase-contrast and monochromatic computed tomography scanner are provided. In addition, a method of identifying an ...
