9.3.1 Brief Description and Operating Principle
AIRO Description AIRO is a 3rd-generation high resolution, large bore (107 cm), 51.2 cm field of view, X-ray
Computed Tomography Scanner.
A ‘scan’ is comprised of a set of 2D axial slice images that are reconstructed from a series
acquisition of 2D-projection images. Its design accommodates intra-operative use. The surgical
column and patient support are controlled using an integrated keypad or a wireless remote control.
AIRO includes a hand-held control unit for imaging, transport, service, calibration, and
remote control used for the integrated table column and associated tabletops.
Essential
Performance
AIRO is a mobile system thats deliver X-ray computed tomography in various environments. When
in use, AIRO provides CT images with:
• No unrequested motion
• No unrequested X-rays
• No non-obvious image quality issues
• No incorrect transmission of image data
Helical Scan Mode
AIRO combines a treatment-specific patient support system and an x-ray imaging device that
produces high resolution helical images of the body.
It operates by continuous rotation of an x-ray tube and opposing detector elements that irradiate the
scanned object from 360 degrees while simultaneously translating with respect to the patient along
the patient Z-axis a (Figure 151) following a precise motion profile.
