Select this button to invoke the Past exam dialog. (Only available if application is OB)
It is possible to switch between fetus tables, if more than one fetus is entered in the patient
dialog page.
This dialog is used to enter data from previous ultrasound exams, performed on other
systems. This data can then be used for fetal trending (graphs). Which measurements are
listed depends on the current measure setup settings. On all further pages the measurement
columns change but the exam date column remains the same.
If no LMP is available the system uses the current date – the length of pregnancy used for
calculations.
This field shows the start and the end date of the Exam.
