Introduction to CTB - Video Tutorial
Video format on the use of Harrison.ai CT Brain (CTB)
Frequently Asked Questions
- Do I use CTB in place of my PACs viewer?
No, the CTB viewer displays a compressed JPEG rather than the full DICOM image. We recommend using the Harrison Viewer along-side your PACs to interrogate the findings listed.
- Can I expand the application automatically to reduce clicks?
Yes, the application behaviour can be adjusted using the settings (cog) icon. See the Settings Guide (interactive or video) for more details.
- What does the term child findings refer to?
Child findings are additional clinical detail provided by the model. For example, haematoma (parent finding) can be further classified into extra-axial or subdural (child findings).
- How should I interpret the confidence bar and the detection threshold?
The confidence bar provides a human element to the AI output. This can be used to inform your clinical judgement as to the presence/absence of each finding. Each finding must meet a threshold to be listed in the viewer; this threshold is shown as the vertical white bar on the confidence scale.
- Can I change the group which a finding belongs to?
Yes, this can be updated to match your practices clinical needs. Contact your customer success manager for more information.
- Is it possible to adjust the thresholds of findings?
In most cases yes, contact your customer success manager for more information.
- What findings does CTB detect?
There is a full ontology tree (findings list) available here. Keep in mind that your specific practice may have a customised findings list, contact your system administrator or customer success manager for the exact configuration.
