Hi Claudia,
I don't see any error in your code. I use a similar approach, which works fine:
// initialize
mitk::Image::Pointer image = mitk::Image::New();
image->Initialize(mitk::PixelType(typeid(unsigned char)), dimension,
dimensions); // dimension = 4
// Fill with zeroes (optional)
unsigned int byteSize = sizeof(unsigned char);
for (unsigned int dim = 0; dim < dimension; ++dim)
{
byteSize *= image->GetDimension(dim);
}
memset(image->GetData(), 0, byteSize );
// Fill a time step
mitkIpPicDescriptor* currentVolume =
resultImage->GetVolumeData(0)->GetPicDescriptor(); // resultImage is 3D
image->SetPicVolume( currentVolume , currentTime );
// currentTime is counted up
Could you please try it this way, too? Maybe there is a bug in
SetImportVolume().
Best,
Tobi

Betreff: [mitk-users] Saving 3D data over time into one mitk::Image
Hi,
I want to write some 3D data over time into a mitk::Image.
What I do is the following:
void MyImageData::Initialize(mitk::Image::Pointer image, int nrOfVolumes)
{
unsigned int *d = image->GetDimensions();
d[3] = nrOfVolumes;
imageSeries = mitk::Image::New();
imageSeries->Initialize(image->GetPixelType(), 4,d,1);
initialized = true;
}
bool MyImageData::pushDataBack(mitk::Image::Pointer image)
{
if (initialized)
{
imageSeries->SetImportVolume(image, time);
imageSeries->GetData();
imageSeries->Update();
if(imageSeries->IsVolumeSet(time))
{
time++;
return true;
}
return false;
}
else
return false;
}
It works fine for the first image. After that I get exceptions in the
memory management. I tried all variants of
mitk::Image::ImportMemoryManagementType in the SetImportVolume-function.
As I understand the concept of mitk::Image I can save data with the
same region and data type over time just by increasing the time
variable, right?
Can anyone help me, please?
Best regards,
Claudia
