This Chrome extension ("Synthesis Worksheet Import - TA," "the Extension") is provided by Radiology Associates of San Luis Obispo ("RASLO," "we," "our") for internal use by our authenticated workforce. It is not publicly distributed and is not intended for use by individuals outside our organization.
The Extension assists radiologists by extracting data from technologist worksheets and measurement screenshots displayed in Synthesis Health PACS, then importing that data into the FINDINGS section of the radiologist's active report. The radiologist reviews and edits all output before signing the report.
Pathology Report Addendum. When the radiologist uses the addendum workflow, the extension captures images of pathology reports displayed in the Synthesis PDF viewer or imaging panels. These images are transmitted to our backend for AI-assisted transcription and inserted into the radiologist's addendum field. Patient identifiers visible in pathology report images are redacted by the AI during transcription. The same data handling, audit logging, and retention policies described above apply.
When you use the Extension, the following data is transmitted from your browser to our internal backend:
Authentication data. Your Google Workspace email address (associated with your @ra-slo.com account) and an OAuth bearer token obtained via Chrome's identity service. These are used to verify that you belong to our organization and to associate each request with a specific user for audit purposes.
Report content. The text of the radiology report draft you are currently editing, including any pre-populated metadata, clinical information, and findings text. This may contain Protected Health Information (PHI).
Worksheet and measurement images. Image captures of technologist worksheet panels and measurement screen snapshots that you explicitly select within the imaging viewer. These images may contain PHI, including patient identifiers visible on worksheets or screen captures.
Operational metadata. Exam type, request timestamp, latency, image counts and sizes, and processing status. Used for performance monitoring and audit logging.
Data submitted through the Extension is processed for one purpose: to assist you in drafting the FINDINGS section of a radiology report. The processing pipeline is:
Your browser sends the report draft and selected images to a Google Apps Script web app deployed within our Google Workspace organization.
The Apps Script calls Google's Gemini API to extract structured findings from the images and merge them into the report template.
The Apps Script returns the generated text to the Extension, which displays it for your review.
You decide whether to insert the generated text into your report.
A record of each request is logged to an internal Google Sheet within our Workspace, accessible only to RASLO administrators. The log includes the requesting user's email, timestamp, exam type, image count, the system prompt sent to the AI, the AI's output, and any error information.
Data is transmitted to two Google services:
Google Apps Script, which hosts our internal backend. Apps Script operates within our Google Workspace and is governed by our existing Google Workspace agreements.
Google Gemini API, which performs the AI text extraction. This service is operated by Google. RASLO is in the process of executing a Business Associate Agreement (BAA) with Google for HIPAA-eligible AI services (Vertex AI). Until that BAA is in effect, the Extension is treated as a limited-deployment internal tool and PHI exposure is mitigated through user training, restricted distribution, and audit logging. Patient names are stripped from the request payload by the Extension before transmission.
We do not transmit data to any other third party. We do not use the data for advertising, profiling, training of external AI models, sale, or any purpose unrelated to the Extension's stated function.
Audit log entries in the internal Google Sheet are retained indefinitely by default; we may establish a periodic retention policy based on operational needs. The Extension itself does not persist any data on your device beyond Chrome's standard short-lived OAuth token cache, which Chrome manages independently of the Extension. No browser-local copy of report content is retained between sessions.
Use of the Extension is voluntary and may be discontinued at any time by uninstalling the Extension or by signing out of your Google Workspace account. As a member of our workforce, your use of the Extension is also governed by our organization's HIPAA, security, and acceptable use policies.
If you have questions about how data is handled, or if you wish to request review of an audit log entry associated with your account, contact: tauran@ra-slo.com.
Communication between the Extension and the backend is conducted over HTTPS. Authentication is gated by Google Workspace single sign-on; only users authenticated against our ra-slo.com domain can access the backend. The Gemini API key used by the backend is held in Google Apps Script's protected Script Properties storage and is never transmitted to client devices.
We may update this policy from time to time. Material changes will be communicated to RASLO workforce members through our standard internal channels. The "Last updated" date above reflects the most recent revision.
