Navigate Through Time‑Lapse Embryo View
The Embryo View organizes and controls the embryo'sover time in frames. Like films, Embryo View divides the length of time into frames.

The Current Time Display
Shows the timecode for the current frame in the time‑lapse represented as the time from fertilisation. To move to a different time, place the pointer over the time ruler.
Playhead indicates the current frame displayed in the time‑lapse. The playhead is an orange-colored time label in the ruler. A vertical line extends from the playhead to the top of the Graph area. The current number of cells is displayed on the top of the playhead's vertical line. You can change the current time by moving the mouse cursor.
The Time-Ruler measures the time‑lapse sequence's time horizontally. Tick marks and numbers indicating the sequence time from display mode. The next-nearest event is displayed as a blue circle.are displayed along the ruler. The time ruler also displays icons for markers and events according to the selected
By dragging the ruler, you can scroll the visible part of the time ruler. When you drag the ruler, you are not animating the time‑lapse.
Displays a set of graphs representing the activity of morphokinetic markers according to the selected display mode. You can display all six modes at a given time point in the Graph Area.
By dragging the graph area, you can scroll the visible part of the graph area. When you drag the graph area, you are not animating the time‑lapse.
By placing the pointer over the left or right edge of the graph area, you can scroll the visible part of the graph area.
When the timebase of the time‑lapse differs from the ICSI timing, there is a blank space at the beginning of the graph area representing the difference of ICSI timing and the time‑lapse start time.
Morphokinetic Display Modes
Display modes section lets you hide or show time‑lapse image and viability morphokinetic marker graphs such as, , , , .
Displays animated time‑lapse embryo photography. time‑lapse embryo photography is a series of microscope photos taken every 30 minutes. You can animate the time‑lapse by clicking on the Play Button or by hovering the mouse cursor over the Timeline or the Chart Area. To move the time‑lapse backward, move the mouse cursor to the left and vice-versa.
The time‑lapse, the Graph Area and the Timeline are animated simultaneously.
Cell Divisions Mode
Displays a binary tree representing series of the.
Parts of binary tree which are highlighted in light-blue color represent mitotic sequences
Because of the limited capabilities of time‑lapse Imaging systems, the most top node is used to display mitotic sequences.
Displays a graph of the. The horizontal axis of the graph represents time from fertilization and the vertical axis represents the output level of cell activity.Show on time‑lapse
Displays a graph of the. The horizontal axis of the graph represents time from fertilization and the vertical axis represents the area of the embryo inside the zona pellucida (in px).
The edges of the line segments display circle symbols that indicate the timing of three morphokinetic markers indicating embryo’s ability to hatch —, and .
Start of Expansion
Start ofis displayed as a circled upward-arrow symbol. The horizontal position of the symbol indicates the time when expansion starts. The vertical position of the symbol indicates the volume of the area of the embryo.Show on time‑lapse
End of Collapses and Mitotic Pulses
or are displayed as a circled downward-arrows symbol. The horizontal position of the circle indicates the time when expansion starts. The vertical position of the symbol indicates the volume of the area of the embryo. The symbol color varies by collapse type.Show on time‑lapse
Displays Show on time‑lapserepresented as horizontal bars. Caption above the bar indicates the name of the mitotic cycle. The mitotic cycle bar is grey by default and the bar gets highlighted in light-blue color when the playhead position matches the mitotic cycle time range.
Select this mode to displaycalculations. As the mitotic sequences, these are represented as horizontal bars. Caption above the bar indicates the name of the cleavage interval. The cleavage interval bar is grey by default and the bar gets highlighted in light-blue color when the playhead position matches the cleavage interval time range. Cleavage step-line chart is displayed along the bars, the chart is represented by a series of cleavage timings. The horizontal axis of the graph represents time from fertilization and the vertical axis represents the number of cells currently monitored.Show on time‑lapse
Embryo Day‑Five Grade
Shows the grade (e.g. 1AA) and its implantation potential according to Day‑Five Embryos Grading System methodology. The grading is at the upper left corner of embryo view.
Compare to Other Embryo
Time‑lapse embryo comparison allows you to compare different time‑lapse embryo images side by side. Learn how to do it.
