From these, it is easy to calculate the area (in cm 2) of the aortic valve by simply dividing the LV stroke volume (in cm 3) by the AV VTI (in cm) measured on the spectral Doppler display using continuous-wave Doppler. [citation needed] Stroke volume = 0.785(π/4) x Diameter 2 x VTI of LVOT Cross sectional area of LVOT = 0.785(π/4) x LVOT ...
The VTi Engine (Variable Valve Lift and Timing injection) is a variable valve timing (VVT) system for Prince engine created jointly by both PSA (Peugeot, Citroën, DS Automobiles) and Mini from the BMW Group.
VLSI's datapath compiler (VDP) was the value-added differentiator that opened the door at Ericsson in 1987–1988. The silicon revenue and GPM enabled by VDP must make it one of the most successful pieces of customer-configurable, non-memory silicon intellectual property (SIP) in the history of the industry.
Velocity Time Integral is a clinical Doppler ultrasound measurement of blood flow, equivalent to the area under the velocity time curve. The product of VTI (cm/stroke) and the cross sectional area of a valve (cm2) yields a stroke volume (cm3/stroke), which can be used to calculate cardiac output.

The VTi is a continuously variable transmission for automobiles. It is fully-automatic, electronically-controlled, and designed for transverse front-wheel-drive use. The VTi is assembled at a General Motors/Fiat joint venture plant in Szentgotthárd, Hungary. Quality issues delayed the introduction of the VTi until the second quarter of 2002.
