An experimental in vitro setting with a latex miniature balloon was designed to test the accuracy of volumetric measurements by spatiotemporal image correlation. Two‐dimensional images clearly showed the round balloon as a thin echogenic ring in a translucent area. Four‐dimensional reconstructed images, however, showed a severely distorted balloon. The artifacts disappeared when the surroundings of the balloons were made echogenic, mimicking the in vivo setting. We hypothesize that the artifacts were the result of gating errors. These experiments can be relevant for analysis of spatiotemporal image correlation volumes in daily practice.
