Meanings
- uncountablemedicineThe act of scanning beyond the boundaries of what is being imaged, usually in order to accurately reconstruct the edges of that region.
Overranging was instituted to take full advantage of the upper limits of a range . It also provides better accuracy at the top of a range .
1985, Alvis J. Evans, Using Your Meter: VOM and DVM Multitesters, page 153 more examples
To reconstruct the first and last sections of a helical computed tomographic (CT) scan, the scan length is automatically extended beyond the planned image boundaries, a phenomenon known as overranging.
2010 July 4, Arnold Schilham et al., “Overranging at Multisection CT: An Underestimated Source of Excess Radiation Exposure”, in RadioGraphics, volume 30, number 4, →DOIOverranging allows a DVM to measure voltage values above the normal decade transfer points without the necessity of having to change ranges.
1983, Stanley Wolf, Guide to Electronic Measurements and Laboratory Practice, page 118In helical scanning, exposure is needed before the start and after the end of the planned scan range in order to reconstruct images at these positions [46]. This overranging requires at least one extra gantry rotation, even though only a small portion of this data is utilised for image reconstruction.
2016, Joel H. Bortz, Aarthi Ramlaul, Leonie Munro, CT Colonography for Radiographers
