The named CT windows

Description

The windows radiologists use, as c(centre, width) in Hounsfield units. Pass a name to segmentation_data() rather than the numbers; this is here for looking them up.

Usage

ct_windows()

Details

Held here rather than fetched from the engine so that looking up a constant does not require starting Python. A test checks the two lists against each other whenever the engine is available, so the copy cannot quietly drift.

Value

A named list of c(centre, width) pairs.

Examples

library("rplatypus")

ct_windows()$lung

centre  width 
  -600   1500 

ct_windows()[["soft_tissue"]]

centre  width 
    40    400
