[vtkusers] DICOM Reader vs vtkImageReader2 reading rates

[leandro]

Hello,

I use vtkDICOMReader to read a DICOM CT data and compared with
vtkImageReader2 using the Software "Process Explorer", wich shows me the I/O
activity of my application. 

I found out that when I use DICOM Reader the "Read Bytes Delta" rate is alot
variable (11 till 70 megabytes, but most of the time more than 60MB). It
takes 10 - 15 seconds to load 800MB Volume. But when I use vtkImageReader,
this  "Read Bytes Delta" rate keeps constantly around 36MB and it takes
around one minute to load the data.

I find it curious because the DICOM reader class is derived from
vtkImageReader2. Does anybody know why both behave different and if this is
changeable?

Peace
