Block diagram describing the parallel classification strategy composed by three joint classifiers (“Elbow classifier”, “Wrist classifier” and “Hand classifier”), each trained with a different TrainingSet. F: elbow flexion; FO: elbow flexion with hand open; FC: elbow flexion with hand close; FS: elbow flexion with wrist supination; FP: elbow flexion with wrist pronation; FOS: elbow flexion with hand open and wrist supination; FOP: elbow flexion with hand open and wrist pronation; FCS: elbow flexion with hand close and wrist supination; FCP: elbow flexion with hand close and wrist pronation; E: elbow extension; EO: elbow extension with hand open; EC: elbow extension with hand close; ES: elbow extension with wrist supination; EP: elbow extension with wrist pronation; EOS: elbow extension with hand open and wrist supination; EOP: elbow extension with hand open and wrist pronation; ECS: elbow extension with hand close and wrist supination; ECP: elbow extension with hand close and wrist pronation; C: hand close; CS: hand close with wrist supination; CP: hand close with wrist pronation; O: hand open; OS: hand open with wrist supination; OP: hand open with wrist pronation; S: wrist supination; P: wrist pronation; NM: no motion class

Various radiographic modalities performed on a patient with elbow osteoid osteoma presented in this study: a plain radiography anteroposterior projection image of the right elbow affected by osteoid osteoma; b sagittal MRI projection image of the right elbow showing mild signs of elbow oedema; c axial MRI projection image of the right elbow showing signs of elbow oedema; d sagittal magnetic resonance arthrography projection image of the right elbow showing signs of elbow oedema; e axial magnetic resonance arthrography projection image of the right elbow showing signs of elbow edema; f sagittal CT projection image of the right elbow with an arrow pointing to the osteoid osteoma site in between coronoid and olecranon fossa; g axial CT projection image of the right elbow with an arrow pointing to the osteoid osteoma site in between coronoid and olecranon fossa; h 3D reconstruction CT image of the right elbow demonstrating osteoid osteoma site from the anterior view; i 3D reconstruction CT image of the right elbow showing osteoid osteoma site from the posterior view
