| "goal_text": "The orthogonal scouts have been acquired. Accurately prescribe the initial two-chamber long-axis localizer; its row is open.\n\nANATOMICAL CRITERIA:\nThe plane should contain the LV apex and midpoint of the LV–LA junction and show the LV and left atrium without foreshortening. Where available, a four-chamber view provides a long-axis reference. Where a ventricular SAX stack is available, the intersection should follow the LV anterior/inferior-wall orientation, approximately parallel to the lateral wall where identifiable, while remaining outside RV tissue at the relevant LV-containing levels. The long-axis plane should be approximately perpendicular to the SAX planes. Consistency across reference views matters more than an appealing appearance in one image.\nThese XCAT reference images are diastolic; valve leaflets may not be visible. Use the midpoint of the LV–LA junction and the LV apex to define the LV long axis. A short-axis plane is perpendicular to that long axis.\n\nENDPOINT: The requested prescription has been successfully submitted. Return done at that point; later workline rows are outside this task. Completion of later acquisitions is not required.", | |
