Isotropic means that properties at any point within a medium are equal in all directions.

Anisotropic (not isotropic) describes different properties in different directions.

The Koning CT, a Cone Beam CT, provides high spatial and true isotropic resolution at lower dose levels than current CT units. The Koning CT for Breast was introduced at RSNA 2006 and is not cleared for sale in the USA.

On October 19, 2001, Philips Medical Systems completed an acquisition strategy through its purchase of Marconi Medical Systems.
The History of Marconi Medical Systems
2001 Royal Philips Electronics and Marconi plc announced that Philips has agreed to acquire Marconi Medical Systems for $1.1 billion.
2000 Marconi introduces Infinite Detector Technology for Mx8000 multislice CT scanner, which acquires an unprecedented 16 simultaneous slices with sub-millimeter isotropic accuracy.
1999 At RSNA, Picker International unveils the new Marconi Medical Systems name and corporate vision.
1998 Picker International acquires the Computed Tomography Division of Elscint Ltd, immediately positioning Picker at the forefront of major global CT suppliers.
1986 Picker produces the industry's first 1.0T MR imager.
1981 Picker is sold to General Electric Co. Ltd. of England (GEC). Picker merged with Cambridge Instruments, GEC Medical, and American Optical to form Picker International.
1967 The name changed from Picker x-ray to Picker Corporation. Picker acquired Dunlee.
1946 The Dunlee Corporation started in Chicago by Dunmore Dunk and Zed. J. Atlee to meet demand for quality x-ray tubes and special purpose tubes.
1915 James Picker Company formed in New York City offering sales and service of x-ray equipment, film and accessories.

Multiplanar reconstruction or reformatting is a post-processing technique to create new images from a stack of images in planes other than that of the original stack.
The use of thin slices increases the spatial resolution in the scan axis direction, allowing a high spatial resolution in all planes. Isotropic resolution results in high quality multiplanar and 3D reconstructions which are of particular benefit in CT angiography and virtual colonoscopy studies.
