WebApr 11, 2024 · Freehand 3-D ultrasound systems have been advanced in scoliosis assessment to avoid radiation hazards, especially for teenagers. This novel 3-D imaging method also makes it possible to evaluate the spine curvature automatically from the corresponding 3-D projection images. However, most approaches neglect the three … WebAug 28, 2014 · Freehand three-dimensional (3D) ultrasound has the advantages of flexibility for allowing clinicians to manipulate the ultrasound probe over the examined body surface with less constraint in comparison with other scanning protocols. Thus it is widely used in clinical diagnose and image-guided surgery. WebFeb 1, 2024 · A total of 120 ultrasound images at each depth (9, 11, 13, and 15 cm) were collected by freehand. The resolution of the ultrasound image was 900 × 680. In addition, a string mockup was constructed to evaluate ultrasound probe calibration accuracy. lag hundar
