I have been trying to use Slicer to take measurements using the ruler tool on JPEG images of a chicken embryo heart. The heart is only about 5 mm across and I have been getting measurements around 300 mm across the heart from the ruler. I tried to manipulate the information in the volume module using the image information. However, the image became extremely zoomed in and I am unsure as to why this occurred. Is there any way that I should be manipulating the volume information so that I can get a proper view of the heart along with correct measurements? The image information is is below and I set the image dimensions to 512 mm x 512 mm x 512 mm and the image spacing to be 16 mm.
VolumeSize 512 512 512
VolumePosition 0 0 0
VolumeScale 0.020 0.020 0.020
Field 0 (Position 0 Size 16 Name “data” Format ui Scale 0.588235 Offset -1294.117676)
I would appreciate any help!
