A revolutionary 3D imaging solution for patient positioning and real time surveillance, providing speed and accuracy, driven through a simple and intuitive user interface. This non-invasive system does not require the use of any markers and adds no further irradiation. 
AlignRT® employs proprietary 3D imaging technology to produce high resolution and accurate 3D surface data referenced to the treatment isocentre. AlignRT® utilises two or three ceiling mounted 3D camera units, designed to image the patient at simulation or treatment. Before commencing treatment, a reference surface model is produced by either acquiring a 3D surface with AlignRT®, or by importing contours, extracted from CT data, via the DICOM RT import module. At each treatment fraction, the system images the current patient position instantaneously. AlignRT® is able to gate its image capture so that 3D data are acquired at a reproducible point in the breathing cycle. State of the art surface matching software registers these data to the reference surface within seconds. Couch shifts are displayed to show inconsistencies between existing and ideal treatment positions. New co-ordinates for the optimal couch position are then displayed and may be applied. Interfaces are available to allow auto adjustment of certain third party treatment couches*. < Back to AlignRT Overview | Tools are provided to allow the user to compare the treatment position with the reference surface both inside the room and remotely. These include a colour coded display, quantitative statistics and SSD checking functionality. With the advent of image guidance and higher precision radiotherapy, there is an increasing need for continuous surveillance and the monitoring of any intra-fraction patient movement. AlignRT® provides an advanced real time 3D surveillance capability which may be used remotely from the control room. This tracks patient motion in all six degrees of freedom, displaying translations and rotations about all three axes, in real time. Any movement that exceeds user defined tolerances is detected and the radiation beam is held automatically*.
