The Effect of Position on Radiographic Angle Measurements of the Lower Extremities

Figure 1

Models of three commonly used reconstruction algorithms. Each box indicates a voxel on the ray and a lighter box represents a higher Hounsfield value. Maximal intensity projection (MIP) represents the pixel with the highest Hounsfield number (a); the minimal intensity projection (MinIP) represents that with the lowest Hounsfield number (b); and the average intensity projection (AIP) represents the average (c).
