GAYA Analyzer SDD Presentation

GAYA Analyzer Introduction • OMS 40 G 256 is a hardware device used for detection of radioactive radiation for medical imaging systems. The detector is built from a matrix of 16*16 pixels • The detectors can connect to an electronic board – Hardware SDK. • The Hardware SDK registers events (radioactive particle impact) generated by the detectors. • The SDK can collect the events as raw data or build particles energy histogram for each pixel individually. • The collected data can be transferred to a PC for further processing.

GAYA Analyzer Working Environment

GAYA Analyzer Main Requirements • Allow the device developers to test it during the different development phases. This will include: o Retrieving data from the device o Analyzing the retrieved data using different algorithms o Displaying the histograms and the analyzed data received from SDK. • Allow calibration of the device for developers / future customers. • Provide an API to communicate with the device: o The API will include a variant set of methods that will allow the future customers to develop software that will be used to test / control the device. o The API will publish only the device abilities that Orbotech sees fitting to expose to future customers.

GAYA Analyzer Testing • Unit-Tests: Every method in the Service Layer API and the Application managers will have a test. • SDK “Simulation State”: In “simulation” state the SDK simulates an image acquisition and creates events and histograms as in operational mode. • Data Integrity Verification: Writing histogram into SDK memory and retrieving the histogram back via Service Layer API. • Functional Tests will be done on the UI, to verify completeness of the whole application.

GAYA Analyzer Task List Remaining tasks: 1 st Milestone: Prototype (End Of March) • Write the interface for image acquisition in the service layer API • Write the application layer code for retrieving the image from the services layer, and analyzing the results.

GAYA Analyzer Task List – Cont. 2 nd Milestone: Image Analysis (End Of April) • Write a generic system for sending commands to the device. • Write the image acquisition thread. • Write the image acquisition display. • Write the image analysis for other parameters.

GAYA Analyzer Task List – Cont. 3 rd Milestone: Calibrations (End Of May) • Write the service and hardware layers commands for calibrations. • Write the application calculation of gain and offset. • Write the code for initializing new module in all layers.

GAYA Analyzer Task List – Cont. 4 th Milestone: Testing (End Of June) • Run all the functional tests for the system, as detailed in the ADD. • Write all the documentation needed for the project: User Manual, Design Docs, etc.
