Automatic Evaluation of Progression Angle and Fetal Head Station through Intrapartum Echographic Monitoring

Figure 7

Scatter plot showing the progression angle (PA) measurements, performed on a 32-year-old parturient at the 38th week of gestation, obtained through the automatic algorithm against the measurements obtained from the expert operator (standard reference), provided with the respective 𝑅². The line of equality is also shown. At the stage of labor corresponding station “−1” and “0”, 1 point out of 20 is overlapped due to the lack of progression in consecutive PA measurements.
