Computed Tomography Equipment Techniques

The process of estimating the value of a missing data point based on existing data points.

A computer program that uses interpolation methods to estimate missing data points.

Data that is used to estimate missing data points.

The value of a missing data point that is estimated using interpolation.

The data that is missing and needs to be estimated.

A technique used in CT scanning to create a detailed image of the body from a series of slices.

The ratio of the distance the table moves between successive scans to the slice thickness.

A higher pitch value in CT scanning results in a faster scan time but with potential trade-offs in image quality.

A lower pitch value in CT scanning leads to a slower scan time but often with better image quality.

The process of creating new slices (images) between existing slices to create a uniform 3D dataset.

A 3D dataset where all dimensions (x, y, z) have the same resolution (voxel size).

The path of the X-ray beam as it rotates around the patient during a CT scan.

The process of adjusting the acquired CT data to account for the helical movement of the X-ray tube and patient table.

A type of CT scan where the X-ray tube and patient table move continuously during the scan.

A scanning technique where the X-ray source moves in a helical path around the patient, acquiring data along a spiral trajectory.

The data acquired during a helical CT scan is collected in a helical pattern, reflecting the movement of the X-ray source.

Conventional reconstruction algorithms are not suitable for processing helical CT data due to its unique spiral data acquisition pattern.

The ratio between the distance the table moves between successive scans and the slice thickness.

A higher pitch value indicates a faster scan time but may result in lower image quality, while a lower pitch value gives a slower scan but often leads to better image quality.

The process of estimating the value of a missing data point in a 3D reconstruction using the surrounding data.

The values assigned to the data points around the missing data point, determining how much influence they have on the estimated value.

The process of calculating the missing data point based on the weighted average of surrounding points.

The degree to which the weighting factors change depending on the angle of the X-ray beam.

The final 3D image of the object is constructed from numerous X-ray projections taken at different angles.

A CT scan technique where data is collected across a larger area, enabling the creation of 3D models of the scanned region.

The process of using data collected from a volume imaging CT scan to create a three-dimensional representation of the scanned region.

CT scans that use a linear motion to acquire data, leading to a series of cross-sectional 2D images.

Traditional CT scans create 2D images, while volume imaging CT captures data across a larger area, resulting in 3D models.

The 3D models created from volume imaging CT scans allow for a more comprehensive view of the scanned region.
