Experimental setup to investigate chondral regeneration potential using biosensitive MR sequences on an established minipig model. (A) Knee specimens (*) were placed in the supine position, feet first, in a clinical knee coil (ρ₁, which is open for better illustration) and fixed with mechanical positioning aids such as pads (§) and cloths ($). Marker lines (black arrows) located on the coil were used for standardized specimen placement. Here, the knee joint (blue ellipse) was placed centrally in the coil. (B) Once the knee sample was centrally positioned in the knee coil, the coil was closed (ρ₁ and ρ₂) and then positioned centrally in the MRI using the reference markings on the top (𝝯) of the coil.
