Computer Vision Tutorial: Lateral Cervical

Print
< Back

The computer vision module requires a valid technical support maintenance agreement and is available only in the CBP Technique version. Currently it is offered on lateral cervical, lateral cervical flexion, and lateral cervical extension radiographs, with additional views planned as research progresses. This module interfaces with our proprietary patent-pending cloud software; an active internet connection and current technical support maintenance agreement are therefore required. If the technical support maintenance agreement is cancelled or expires, access to the computer vision module, PostureRay online database backups, and the browser-based Virtual ViewBox will be discontinued. PostureRay remains fully functional in manual digitization mode, exactly as it operated prior to versions 25 and 26.

Computer vision is solely a time-saving tool that places measurement points in an approximate location. It does not replace clinical judgment. The doctor remains fully responsible for validating every single point before completing an assessment. Just as the doctor would be required to review and correct points placed by an assistant, the doctor must review and, when necessary, drag every computer-vision point into the precise anatomical location. Any mis-marked segment must be corrected by the doctor. Only after the doctor has personally validated and accepted all digitization points may the resulting measurements be incorporated into the patient’s health-care record.

The doctor remains fully responsible for any clinical significance assigned to the documentation, because the doctor alone retains complete control over editing and finalizing every annotation point.

In the above example we demonstrate proper bounding box technique for application of the computer vision This step is done after the cropping of the x ray if that step is needed Please note that you must use a close and tight bounding box which includes anterior and posterior tubercle of C1 and vertbral body of C7 Do not include T1 The inferior boarder will be right outside the vertbarl body into the disc space based on overall alignment of the cervical spine On some neck postures the bounding box will be very narrow however in larger forward head postures the bounding box will need to be wider In the case of flexion and extension films the mox is wider as well for obvious reasons however you always should attempt to only include the vertbral body of C7 up to C1 If this box is too large you will introduce increased incidence of error As always make sure to double check and correct any anatomical landmarks if needed and after the application feel free to add additional anatomical locations not included in the computer vision
