Regional Models - Lower Limb

[RobFarrugia]

Hello!
I am trying to create a bioheat simulation of the human lower limb. I am currently using the latest Yoon-sun posable model. I would require detailed vascular anatomy of the forefoot for this (beyond the tibial artery).

Are there any available lower limb regional models? What is the best way to go about this?

Thank you in advance,
Robert
