10 Measuring Wound Area
The iX Camera App wound measurement functionality features wound border detection, wound area measurement, and
wound length & width measurement capabilities. The wound border may be traced automatically (Auto Mode) or manually
(Manual Mode). Wound area measurement should only be performed on images captured in Standard Imaging Mode with
the use of MolecuLight WoundStickers. Refer to Appendix E for additional details on the iX Camera App wound
measurement functionality.
The wound measurement functionality should only be used on images captured in Standard Imaging
Note
Mode and should not be used on images captured in Fluorescence imaging mode.
The use of 2 MolecuLight WoundStickers may produce an average wound measurement error (Area
Note and Dimension) of 5%, when the image is taken with MolecuLight WoundStickers in the plane of the
wound.
Note In the absence of MolecuLight WoundStickers, no area measurement is provided.
The use of only 1 MolecuLight WoundSticker may produce an average wound measurement error (Area
Caution and Dimension) of 15%, when the image is taken with MolecuLight WoundStickers in the plane of the
wound.
Caution Only MolecuLight WoundStickers should be used for the wound measurement functionality.
Caution Do not place MolecuLight WoundStickers on the wound.

10.1 Settings Menu

The Settings Menu accessed from the Menu Bar enables customization of the wound border thickness, and display of
reported length and width dimensions. The Album
described in Section 9.5.
10.1.1 Wound Border Thickness
The displayed wound border thickness can be modified from the Settings Menu
accessed from the Menu Bar.
By default, the medium border thickness is selected.
Use the slider to modify the border thickness to the desired setting.
The 3 available settings are
1) Thin
2) Medium
3) Thick
10.1.2 Display of Length & Width Dimensions
The display of the Length and Width dimensions can be disabled or enabled using the switch
accessed from the Menu Bar.
When enabled, a selection between "Length & Width"
& Width" setting is enabled where the maximum length and perpendicular width of the wound is displayed on screen
whenever a wound measurement is taken.
When display of dimensions is disabled using the switch
dimensions will no longer be reported on the wound image when a wound border is drawn and saved.

10.1.2.1 Length & Width
By default, the Length & Width setting is enabled:
Once the desired wound border is drawn, Length & Width dimensions will appear as blue and
green lines on the wound and their measurements will be reported in cm.
Wound length (blue line, L) represents the longest dimension of the wound in any direction.
Wound width (green line, W) is drawn perpendicular to wound length.
As wounds change in size over time the orientation of the maximum length of the wound may
also shift and therefore the maximum length may not always be reported from the same part
of the wound using this length and width option.
10.1.2.2 Vertical & Horizontal
Wound dimensions are also available in vertical and horizontal format:
Vertical length (blue line, V) represents the longest vertical distance (top to bottom of the
screen) within the wound boundary. Horizontal length (green line, H) represents the longest
horizontal distance within the wound boundary.
Selecting this method of measuring wounds will allow you to consistently measure the same
axes of the wound for tracking changes in vertical and horizontal wound distances over time.
To measure the wound consistently, wound images must be taken with consistent orientation.
This method of measurement can be combined with the well documented clock method to
accurately detect changes in the vertical and horizontal distances of the wounds.
To take measurements according to the clock method, capture wound images with the
as
MolecuLight i:X in a portrait orientation such that the top of the device is aligned with the head
of the patient and the bottom with the feet of the patient. The measured vertical distance will
be a measurement of the wound from 12-6 o'clock and the horizontal distance will be a
measurement of the wound from 9-3 o'clock.

10.2 Auto Mode

The iX Camera App can automatically trace and measure the area of a wound. The following steps are required for
automated wound area measurements:
1. Ensure the Standard Imaging Mode wound image is captured with 2 MolecuLight WoundStickers (P/N 1266) placed
close to and within the plane of the wound. Measurement accuracy will be degraded if the MolecuLight WoundStickers
are off plane, in which case stickers may appear elliptical. For optimal results, ensure the MolecuLight WoundSticker
placement is at the 1 and 7 o'clock position or at the 11 and 5 o'clock position when holding the MolecuLight i:X in a
portrait (vertical) orientation, as depicted in Figure 22 and Figure 23.
2. When capturing an image, ensure the MolecuLight i:X Camera Sensor is parallel to the wound and the MolecuLight
WoundStickers are in field of view.
3. Open the image of interest from the Image Library
4. The Auto Trace feature traces the border of the wound with a white line (the MolecuLight WoundStickers will be
highlighted with a blue circle during this auto detection process).
5. When selecting Auto Trace, additional icons are available to expand
these icons expands or contracts the wound border as desired.
6. Once the desired wound border is achieved, a Checkmark
