Oblique Axis Rib Stretch and Curved Planar Reformats in Patients for Rib Fracture Detection and Characterization: Feasibility and Clinical Application

Figure 2

Hand-drawn graphics (A1–D1) showed the reconstruction orientation of OARS (A1, C1) and CR (B1, D1) of anterior or posterior limbs: more fracture lines can be shown when using the vertical fracture line reconstruction method (OARS). Orientation (red lines or yellow lines) of OARS and CR of anterior or posterior limbs on 3D images (A2–D2) and sagittal (or coronal) images (A3–D3). Anterior or posterior limbs’ fractures (red circles) displayed on axial images using OARS (A4, C4) and CR (B4, D4). OARS: oblique axis rib stretch. CR: conventional reconstruction.
