1. A medical training model, comprising:
at least one blood vessel model having a hollow anatomically replicated lumen that corresponds to a vascular anatomy, the at least one blood vessel model configured to be connected in at least one practice region to an anatomically replicated substitute blood circulation system, wherein the anatomically replicated substitute blood circulation system is configured to circulate a fluid through the hollow anatomically replicated lumen of the at least one blood vessel model to simulate a physiological property, and wherein the at least one blood vessel model is adapted to receive a non-transparent medical instrument for practice;
an image recording device configured to create measured images of the at least one blood vessel model; and
an image processing device configured to convert the measured images into an imaging blood vessel representation and to display the imaging blood vessel representation on a screen, wherein:
the image recording device comprises a photo-optical system configured to record transmitted-light images as the measured images of the at least one blood vessel model for simulation of medical activity;
the at least one blood vessel model is replicated within a transparent solid-body block, such that a contrast is created between the transparent solid-body block and the non-transparent medical instrument;
the photo-optical system comprises at least one camera and at least one backlight panel, wherein the at least one blood vessel model replicated within the transparent solid-body block is positioned between the at least one camera and the at least one backlight panel such that the transmitted-light images are recordable as measured images of the at least one blood vessel model in backlight; and
the transparent solid-body block is made of a casting compound having a lost shape of an inversely replicated blood vessel model or by an additive manufacturing process.
