Subject: unable to open X server `' (Magick::ImageMagickError)

I have written a Ruby script "dicom_info.rb", and when I try running
it, I get the following error. Why is that? And, how can it get
solved?

C:\Users\Abder-Rahman\Desktop\Research\dicom>ruby dicom_info.rb
Fantomas is 070Y
And, this is the DICOM image
dicom_info.rb:22:in `display': unable to open X server
`' (Magick::ImageMagickEr
ror)
       from dicom_info.rb:22
       from dicom_info.rb:10:in `each_index'
       from dicom_info.rb:10

This is the "dicom_info,rb" script:

require "rubygems"
require "dicom"
require "RMagick"

dicom_files = Array.new
Dir["./dcm_files/*.dcm"].each do |dcm|
       dicom_files << dcm
end

dicom_files.each_index do |i|
dcm = DICOM::DObject.new(dicom_files[i])
# Retrieve patient name value
patient_name = dcm.value("0010,0010")
patient_age = dcm.value("0010,1010")
print patient_name
print " "
print "is "
print patient_age
puts
puts "And, this is the DICOM image"
dicom_image = dcm.get_image_magick
dicom_image.display
end

Thanks.
