R Documentation

Convert gray scale from measured bits to 8bit

Description

Convert gray scale from measured bits to 8bit

Usage

xBitTo8Bit(im, bits)

Arguments

`im`	Matrix of values in x bits
`bits`	Number of bits of the original gray scale

Value

Matrix of gray scale values in 8bits

Examples

library(oro.dicom)
file_path <- system.file("extdata", "disk.dcm", package = "CTRing")
dcm <-  readDICOM(file_path)
hdr_df <- dcm$hdr[[1]]
image_info <- getImageInfo(hdr = hdr_df)

im <- imageToMatrix(dcm$img)
range(im)

im_8bit <- xBitTo8Bit(im, image_info$grayScale)
range(im_8bit)
