format supports 3D+t image sequences more cleanly. At the beginning, we used ITK’s reader/writer, but metadata handling was not fast enough and we also needed dynamic header construction and memory-cached compressed streaming image I/O. We are now also adding
support for lossy video codecs as non-standard extensions.<o:p></o:p></span></p>

<p class="MsoNormal">Hello, I was wondering if it is possible to store additional information about an image as part of an MHA file. Specifically, we are capturing ultrasound using an arm that has encoders attached that report position in space, and I'd like
to be able to include that information in the MHA file rather than keeping a separate record. Thanks in advance for the help.<br clear="all">
