Automated and guided
- Scanning queue definition
The user defines the correct scanning queue based on the local LINAC and TPS setup. This is supported by templates specific to the TPS. The queue can be easily adapted. SMARTSCAN gives guidance for correctly chosen equipment and protocols.
- Measurement parameter optimisation. Automated.
For every beam profile and depth dose curve in the queue, SMARTSCAN automatically determines the optimal scan speed and output step-width.
It chooses the right sensor and electrometer input sensitivity to measure the signal at the highest precision.
- Organising the work. Automated.
Now SMARTSCAN runs a background measurement for every electrometer channel and sensitivity, followed by LINAC dose-rate measurement to determine the characteristics of the LINAC.
For all scanning groups in the queue, SMARTSCAN determines the required LINAC Monitor Units. Based on all this information, SMARTSCAN now sorts the work items to reduce the number of required user interactions and the movement path of the sensor to a minimum.
- Setup alignment check. Automated.
SMARTSCAN performs an automatic LINAC alignment check. This ensures the perfect alignment of the central axes of the beam to the axes of the 3D mechanics, as well as to the water surface.
It automatically corrects minor adjustments to the centre where necessary and appropriate.
- Full system check. Automated.
SMARTSCAN confirms the accuracy of the entire system set-up by running a small set of selected key measurements. If the data quality is poor, the physicist can now tune the setup before starting the extensive series of measurements. Key checks include beam symmetry, dmax value, signal noise, background noise, and scatter influence.
SMARTSCAN now executes an extensive and optimised worklist.
While performing as many measurements as possible automatically, SMARTSCAN guides the user through all required detector changes and inputs on the LINAC console.
- Signal input normalisation. Automated.
SMARTSCAN automatically performs an electrometer signal normalisation at each change of field size, energy or detector.
- Online QA check. Automated.
SMARTSCAN performs an immediate quality check for each measured profile and informs the user in case of detected deviations. SMARTSCAN automatically checks for the correct field size and signal noise behaviour.
