All images in this database are in MINC format, the image format used at the McConnell Brain Imaging Center.
Some useful links:
A few tips:
- Files with the extension .mnc are the image files and those with the extension .tag are text files containing the manually selected homologous landmarks.
- The easiest way to visualize one or two MINC images is to use register.
To view a pair of images along with their tags use the following command:
register image1.mnc image2.mnc landmarks.tag - Files with the extension .xfm are text files containing transformations. To apply a transformation on a .mnc file, use the tool mincresample. To apply a transformation on a .tag file, use the tool transform_tags
- To extract the parameters (translations, rotations, etc) from a linear transformation stored in a .xfm file, use: xfm2param.
- To reconstruct a sweep of 2D images into a 3D volume use volregrid. For example, the command that was used to reconstruct the 3D ultrasounds in this study is the following:
volregrid `volextents -step 0.3 *.mnc` -regrid_floor 0.0001 -linear -regrid_radius 0.3 0.3 0.3 -xdircos 1 0 0 -ydircos 0 1 0 -zdircos 0 0 1 *.mnc 3dus.mnc - volextents is not part of the standard MINC distribution, but you can download it here.
- For each 3D ultrasound provided on this web site, the corresponding 2D slices are also available, which means that you can reconstruct your own 3D ultrasound with, for example, a different resolution.
