What is micro tomography used for?
Microcomputed tomography (microCT or μCT) is a non-destructive imaging tool for the production of high-resolution three-dimensional (3D) images composed of two-dimensional (2D) trans-axial projections, or ‘slices’, of a target specimen.
What is the difference between CBCT and Micro-CT?
Micro-CT has become the “gold-standard” for evaluation of bone morphology and microstructure in the ex vivo bone model or small animal bone. On the other hand, clinical CBCT has been widely applied in dentistry for over two decades. It can offer high image quality with low radiation dose and at low cost.
How is XRAY microtomography?
X-ray microtomography, like tomography and X-ray computed tomography, uses X-rays to create cross-sections of a physical object that can be used to recreate a virtual model (3D model) without destroying the original object. Virtually all tomography today is computed tomography.
How does micro CT scanning work?
Micro-CT is a 3D imaging technique utilizing X-rays to see inside an object, slice by slice. Micro-CT scanners capture a series of 2D planar X-ray images and reconstruct the data into 2D cross-sectional slices. These slices can be further processed into 3D models and even printed as 3D physical objects for analysis.
How long do micro CT scans take?
It depends on the system you are using, the sample you are scanning, the number of pixels being used to image the sample, and the signal quality you are looking for in your results. Some scans can be completed in as little as 80 seconds for low density samples, and some high density scans can take up to 14 hours.
How does micro-CT scanning work?
What is Nano CT?
Nano-computed tomography (nano-CT) is an emerging, high-resolution cross-sectional imaging technique and represents a technical advancement of the established micro-CT technology. Key points: Nano-computed tomography is a high resolution CT-technology for 3D imaging at sub-micrometer resolution.
How is Volume Imaging used in 3D imaging?
Volume Imaging (3D Imaging) Volume imaging is the acquisition of magnetic resonance data from a volume rather than a single tomographic slice. It can be thought of as collecting several contiguous slices through a region of imaged object. The number of contiguous slices will always be a multiple of 2.
What are the principles of multislice and oblique imaging?
The principles of multislice imaging, volume or three dimensional (3D) imaging, and oblique imaging will be introduced. Two new imaging sequences called the spin-echo sequence and inversion recovery sequence will be introduced. Gradient-Echo Imaging
What are the gradients used in oblique imaging?
Oblique imaging is performed by applying linear combinations of the X, Y, and Z magnetic field gradients so as to produce a slice selection gradient which is perpendicular to the imaged plane, a phase encoding gradient which is along one edge of the imaged plane, and a frequency encoding gradient which is along the remaining edge of the image.
How is the orientation of the imaging plane set?
The orientation of the imaging plane is set graphically by the operator after obtaining a set of initial scans through the anatomy. The scanner’s operating system calculates the exact Gz, Gy, and Gxvalues to use to create the Gs, G, and Gfneeded to produce the oblique slice.
