readStaticInterfileIMG: Read interfile binary file format images

In kippjohnson/interfile: Reads Files in the Interfile Format Used in Nuclear Medicine Studies

Description

This function imports static (2D) binary interfile files.

Usage

readStaticInterfileIMG(fname, endian = "little", file.row = 80,
  file.col = 80, what = "double", bytes.per.pixel = 4)

Arguments

fname	Filename of the interfile
endian	Endian-ness of the file you are attempting to read. Permitted values are "big" or "little"
file.row	Rows of pixels in the image
file.col	Columns of pixels in the image
what	Type of binary data stored: permitted values are "numeric", "double", "integer", "int", "logical", "complex", "character", "raw".
bytes.per.pixel	Number of bytes per pixel. This information shold be stored in the header file (.hdr) of the interfile.

Value

A matrix of pixel intensities

Examples

# Load an example interfile (Rabbit aorta, Tc99m scan)
interfile.location <- system.file("extdata", "Tc99m_20percent_energy.img", package = "interfile")

# Read the binary interfile
my_scan <- readStaticInterfileIMG(interfile.location)

# Check out the results (returned as a matrix)
dim(my_scan)
head(my_scan)
