Strict aliasing échographie
A specific use for aliasing in echocardiography is the calculation of the effective regurgitation orifice area in the assessment of valvular regurgitation, most commonly involving the mitral valve. With color Doppler interrogation of a mitral regurgitant jet, a hemispheric flow convergence forms surface area tapering to form the vena contracta ... WebSpecifying Aliasing Restrictions in Source. The strict type aliasing restriction enforced by the C standard disallows pointers to incompatible types from aliasing each other. This allows the compiler to generate more efficient code sometimes.
