Release of Neuro-Functionalized Male ViP Model Jeduk V4-0

Only six months after the release of Yoon-sun V4-0, IT’IS introduces its male counterpart, neuro-functionalized Virtual Population model Jeduk V4-0

We are excited to announce the latest achievement from our Swiss-Korean collaborative project NEUROMAN [1]: the release of next-generation computational phantom Jeduk V4-0! After completing the female phantom Yoon-sun V4-0 in December 2018, the Virtual Population (ViP) library now includes both a male and female Korean neuro-functionalized human computational model to study the mechanisms and optimization of neurostimulation treatments and ensure safety of corresponding devices.

Jeduk V4-0: The Virtual Population now includes both a female and male neuro-functionalized (V4-0) model.

Jeduk V4-0 consists of more than 1200 tissues and depicts an extremely detailed model of the human anatomy. Muscles, nerves, and blood vessels have been segmented, named, and meshed as separate objects, allowing for more accurate virtual placement of devices even by non-medically trained staff. Most importantly, it includes neuro-functionalized nerve trajectories that are modeled as splines and assigned default nerve physiology parameters from the literature. Note that the spline trajectories and tissue anatomy are compatible with ZMT’s Sim4Life NEURO simulation module.

While the development of Jeduk V4-0 has been driven by a vision to combine computational anatomy with neuro-physiology for applications such as magnetic resonance imaging (MRI) gradient safety or spinal cord stimulation for restoring motor control, the richness of the underlying cryosection image data, originally acquired by the Visible Korean (VK) project, offers many opportunities for other applications ‒ from blood flow simulations in the entire arterial/venous network to detailed cochlear modeling.

We are currently working on validating the two neuro-functionalized anatomical models in the context of MRI gradient coil safety, however, we welcome all efforts from the community to validate our next-generation models within different contexts of use. To facilitate this new field of computational neurostimulation research and to support our vision of validated computational simulations in and around the human body, we are releasing the new male model Jeduk V4-0 to the public today, directly after completion.
