With the launch of the Solar Dynamics Observatory (SDO) we now have access to images of the Sun taken continuously, combining unprecedented spatial and temporal resolution. Meridional circulation, an important component in flux-transport solar-dynamo models, is one of the keys to understanding the solar cycle. In this work we concentrate on preliminary attempts at evaluating the constraints of time-distance helioseismology in measuring meridional flows in the convection zone of the Sun by analyzing data from the Helioseismic and Magnetic Imager (HMI) aboard SDO. We estimate the maximum depth into the convection zone that can be achieved using deep-focus time-distance analysis and compare results with current ring-diagram techniques.
