Description, patients and keywords:

The OnSight 3D Extremity System, developed by Carestream, is a cone-beam computed tomography (CBCT) scanner designed to provide 3D images of arms and legs. OnSight is intended to be used for the diagnosis of bone and soft tissue problems of the upper and lower extremities including the elbow, wrist, hand, knee, ankle and foot in patients aged 12 years and over.

OnSight has a swinging door that allows the patient to step into the device. The detector and source rotate around the patient, acquiring multiple projections from different angles. The images are then reconstructed into a 3D model using software. The system can also produce 2D images. The lower extremities can be imaged in both weight-bearing and non-weight-bearing positions, while delivering a lower radiation dose compared to large conventional CT scanners. According to the company, the test and review of the scan can be performed at the point of care and may help reveal subtle or occult fractures.
