Hi Robbie and David,

I am currently reading the data into an array and this is where it
slowing down. Reading all of the files into an OBJARR is relatively
faster but this OBJARR must then have each objects image data read
individually eg I have not been able to do this;

Image_Data = oArray -> GetValue(REFERENCE = image_data_reference, /
no_copy)

Below is what Im currently using.

Cheers
Jye

PRO Example

folder = 'D:\Dynamic\' ;Folder containing all of the DICOM files
files = file_search(string(folder, '*.DCM'), COUNT=nfiles)

dicom_obj = obj_new('GDLffDICOM')
result = dicom_obj -> Read(files[0])

image_Acq_Time_reference = dicom_obj -> GetReference('0018'x,'1242'x)
image_reference = dicom_obj -> GetReference('7FE0'x,'0010'x)

obj_destroy, dicom_obj

for i = 0, nfiles-1 do begin

Slice_Number = i
dicom_obj = obj_new('GDLffDICOM')
result = dicom_obj -> Read(files[i])

image_Acq_Time = dicom_obj -> GetValue
(REFERENCE=image_Acq_Time_reference,/no_copy)
image_Acq_Time = *(image_Acq_Time[0])/1000.

if i eq 0 then Acq_Time = image_Acq_Time else Acq_Time = [Acq_Time,
image_Acq_Time]

image_slice = dicom_obj -> GetValue(REFERENCE=image_reference,/
no_copy)
image_slice = rotate(*(image_slice[0]), 7) / image_Acq_Time

if i eq 0 then All_Images = image_slice else All_Images =
[[[All_Images]], [[image_slice]]]

obj_destroy, dicom_obj

endfor

END
