Results
3 tests were performed on real-time fusion imaging between US,
pSWE and MRI in vivo,
using Automatic Registration algorithm.
6 tests were performed in vitro on the Abdominal multimodality phantom,
regarding real-time Fusion Imaging and Virtual Biopsy.
In all the tests it was possible to perform the US-MRI real-time fusion imaging with automatic target saving of the performed pSWE measurements.
The virtual biopsy test was performed using the mimicking-lesions present in the phantom with the needle guidance; the insertion phase was performed without the US real-time image active (US General Gain temporarily decreased to zero value) and then re-activated after the complete insertion of the needle,
to check the accuracy of the sampling.
The tool worked properly both regarding the phantom tests for manual registration and for virtual biopsy,
being able to center the virtual target.
The co-registration of real time US and pre-acquired MRI scans was always feasible for in-vivo and in-vitro tests,
with a spatial error between 2 and 5 mm.
The automatic registration algorithm increased the level of repeatability,
having the potential to increase the ease of use of real-time multimodality fusion imaging also for non-expert users.
