fluoro {GLMsData}

The time of fluoroscopy and total radiation

Description

The data give the total procedure time during ct fluoroscopic scanning, and the radiation dose received.

Usage

data(fluoro)

Format

A data frame with 19 observations on the following 2 variables.

Time

the total procedure time (in minutes); a numeric vector

Dose

the total radiation dose received (in rads); a numeric vector

Details

The data are given in the Table as the natural log of Time and the natural log of Dose. Here the data have been transformed back to the original scale. The source claims the purpose of the data collection was “to assess whether radiation dose could be estimated by simply measuring the total ct fluoroscopic procedure time”. The procedure was performed in the abdomen.
