Missed diagnoses are frequently associated with suboptimal image acquisition and inconsistent application of fundamental ultrasound optimization principles. High\u2010quality fetal cardiac assessment requires intentional optimization of technical parameters, in addition to acquiring the recommended anatomical views. We describe, in the context of fetal cardiac imaging, the \u2018DAZE\u2019 (Depth, Angle, Zoom, Enhancement) technique, an organized and reproducible approach for systematically optimizing two\u2010dimensional ultrasound imaging and the application of color Doppler. The DAZE technique consists of four sequential steps: \u2018D\u2019, adjustment of Depth and focal\u2010zone placement; \u2018A\u2019, optimization of sector Angle width and Angle of insonation; Z, appropriate Zoom magnification; and E, Enhancement of ultrasound system settings. Practical application of each component is described, with an emphasis on optimizing spatial and temporal resolution on two\u2010dimensional grayscale imaging, as well as optimizing the application of color Doppler. \u00a9 2026 International Society of Ultrasound in Obstetrics and Gynecology.<\/jats:p>","DOI":"10.1002\/uog.70282","type":"journal-article","created":{"date-parts":[[2026,7,2]],"date-time":"2026-07-02T12:40:42Z","timestamp":1782996042000},"page":"130-139","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["How to apply the\n                    <scp>DAZE<\/scp>\n                    technique: structured approach to fetal cardiac image optimization"],"prefix":"10.1002","volume":"68","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1186-5088","authenticated-orcid":false,"given":"M.","family":"Perez","sequence":"first","affiliation":[{"name":"Department of Obstetrics &amp; Gynecology, Division of Maternal\u2010Fetal Medicine Scripps Clinic  La Jolla CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Sklansky","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Pediatrics Cedars\u2010Sinai Guerin Children's  Los Angeles CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Anton","sequence":"additional","affiliation":[{"name":"Department of Reproductive Medicine University of California  San Diego, La Jolla CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.
