A geometric model for the human pulmonary valve in its fully open case

Fig 1. Posterior view of the human pulmonary valve (cf. [3]).

Fig 2. A schematic plot of the human pulmonary valve. (a) is the pulmonary valve during diastole (cf. [15]) and (b) is the pulmonary valve during systole (cf. [18]) (c) is the expanded semilunar valve. A: anterior leaflet, L: left leaflet, R: right leaflet.

Fig 3. The model for the geometrical shape of a cusp in the pulmonary valve. The leaflets is considered to be one-third of the cylindrical shell.

Fig 4. (a)The leaflet shape shown in 3D (b)The leaflet shape shown “laid flat” in 2D.

Fig 5. The boundary curve of the semilunar valve.

Fig 6. Visualization of the right half of the valve cusp in three-dimensional space. (a) is the image of the front view of a single cusp and (b) is the side view.

Fig 7. The combined graph of the human pulmonary valve cusps in three-dimensional space. (a) is the image observed from the front and (b) is the image observed from the top.
