Table 3.
A description of how each breast measurement was digitally calculated, as well as a visual depiction of the measurement in Geomagic.
| Measurement | Description of how the measurement was calculated in Geomagic | Visual depiction of the measurement |
|---|---|---|
| Breast Volume (mL) | From each participant's scan, a three-dimensional, isolated model of each breast was created by outlining the breast (A), removing the breast from the torso (B) and attaching it to the corresponding anterior chest wall (whose curvature approximated the superficial surface of the pectoralis major muscle; C,D). These steps were performed to create a closed three-dimensional breast model (E,F), from which breast volume (mL) was calculated. |
|
| Breast Surface Area (cm 2 ) | Using the closed three-dimensional breast model (E,F), the surface area (cm2) of each participant's right and left breast was calculated. |
|
| Anterior Breast Projection (mm) | Using the closed three-dimensional breast model (E,F), the distance from the posterior breast wall to the most anterior point of the breast was calculated. |
|
| Breast Length (mm) | The linear distance (mm) between the inferior and superior borders of each participant's right and left breast was measured at the longest vertical point. |
|
| Breast Width (mm) | The linear distance (mm) between the medial and lateral borders of each participant's right and left breast was measured at the widest point. |
|
| Sternal Notch to Nipple Distance (mm) | The linear distance (mm) from the sternal notch (where a marker had been placed before scanning) to the nipple of each participant's right and left breast was measured. |
|
| Sternal Notch to Superior Breast Distance (mm) | The perpendicular distance (mm) between the sternal notch and a horizontal line drawn across the torso at the level of the superior border of each participant's right and left breast was measured. |
|
| Sternal Notch to Inferior Breast Distance (mm) | The perpendicular distance (mm) between the sternal notch and a horizontal line drawn across the torso at the level of the superior border of each participant's right and left breast was measured. |
|
Unless otherwise stated, all measurements were taken on each participant's right and left breast and the mean value was recorded.
