| Automated Volume Count software in three-dimensional volume of left ovary, depicting 67 antral follicles |
SonoAVC was
introduced in 2008 (GE Medical Systems, Zipf, Austria), and automatically
identifies and counts follicles in a given ovarian volume because of hypoechoic
nature against hyperechoic ovarian tissue background.
SonoAVC
software is either integrated into the ultrasound device or it can be installed
separately on a PC for the offline analysis of data sets obtained using an
ultrasound device from the same manufacturer. Each volume has its own color,
making SonoAVC an ideal tool for studying follicular development within the
ovary.
Here is a beautiful
picture of the day published on January 3, 2018 in the Journal Ultrasound in Obstetrics
and Gynecology, which depicts the stark contrast between Grayscale
two-dimensional ultrasound images showing follicles vs. automated follicle
counting using Sonography-based Automated Volume Count software in
three-dimensional volume of left ovary, depicting 67 antral follicles.

• A
transvaginal ultrasound is performed using a 3D imaging probe (RIC 5-9 or RIC
6-12)
• Optimize
the gain and harmonics for optimum image quality
• Select 3D
imaging mode, adjust quality settings
• Adjust
volume angle to include entire ovary and acquire volume
• Adjust 3D
box over area of interest
• Select
SonoAVC to evaluate the ovarian follicles
• Increase
or decrease growth or follicular separation
• Select
follicles manually if they are not identified
• Display report and chart
