How to convert dicom images to Jpg format in R

Question

How to convert Dicom images with file extension .dcm to Jpg or Png in R

I am attempting the following code in R, but getting error as Error: '...' used in an incorrect context

What is wrong in my below R code.

source("https://neuroconductor.org/neurocLite.R")
neuro_install('dcmtk')
install_dcmtk()
library(dcmtk)
setwd("D:/train/ID00007637202177411956430")
dcm<-readDICOMFile("27.dcm")
dcmj2pnm(dcm, outfile = tempfile(fileext = ".png"),opts = "--write-png", ...)

Do you want to convert it within your program? If not, you can simply use an online converter. — David Lee, Jul 20 '20 at 09:33
Yes want to convert within R. Not sure what error I am doing in my above code — Vikram R S, Jul 21 '20 at 14:06

Looking at the code for dcmj2pnm.R (https://github.com/muschellij2/dcmtk/blob/master/R/dcmj2pnm.R), it seems that it expects the first parameter to be a DICOM file name. You seem to be passing it DICOM image in memory, not a file name.

Thanks. I should have used file with .dcm extension in my dcmj2pnm command. – Vikram R S Jul 22 '20 at 12:08
