What is isotropic spatial resolution? Isotropic spatial resolution means that the spatial resolution in the transaxial plane (X-Y plane) and that in the longitudinal direction (Z direction) are equivalent. To obtain point spread function (PSF) values in the X-Y-Z directions, three-dimensional voxel data were obtained by helical scanning of a bead phantom.
How do you define spatial resolution? Spatial resolution is a measure of the smallest object that can be resolved by the sensor, or the ground area imaged for the instantaneous field of view (IFOV) of the sensor, or the linear dimension on the ground represented by each pixel.
What is spatial resolution of CT scan? Current CT scanners have a spatial resolution of 0.5–0.625 mm in the z-axis, and approximately 0.5 mm in the x- to y-axes. A basic requirement for adequate multiplanar reconstruction is that the resolution is isotropic; eg, the resolution is approximately equal in all directions.
What is isotropic imaging? Isotropic imaging is characterized by an isotropic spatial resolution, i.e., a spatial resolution identical in the three spatial directions. The main parameters that affect the spatial resolution are the slice thickness, the reconstruction increment, and the reconstruction filter.
