Using TI to convert a phisical machine to a virtual box machine

Hi,
I've read an article on "How to run Acronis bootable partition backup as virtual machine in VMware Workstation", see http://www.file-extensions.org/article/run-acronis-tib-as-virtual-machi….

I'd like to know if it's possible to do a similar operation in order to export my phisical machine running on Windows 7 on a Virtual Box machine and what version of TI should I use.

Thank you in advance.
