Orbitometer flow and thrombus formation.

Orbitometry (Hartert) is a rheological ex-vivo method to follow up physical assembly of a coagulum in layers during natural intensity of flow by orbital movement. Fibrin elasticity in the Orbitometers mode of Resonance Thrombography is differentiated from platelet activity as well as e.g.

Fibrin elasticity and coagulation.

Sudden increase of viscosity in former times indicated the start of coagulation. Yet its measurement destroyed the structure of coagulum. By the precursor method of thrombelastography the author 1944 found elasticity to be the essential physiological property of coagulum.

Resonance thrombography.

Resonance Thrombography is a method to follow up the coagulation process ex vivo from its very beginning up to its final consolidation phase resp. fibrinolysis. The mode of measurement is adopting the resonance effect of fibrin elasticity.
