accelerator gantry isocentricity,
table positioning, laser alignment,
and collimators
LUCY 3-D Plus sphere shown on standard alignment base
LUCY 3-D Plus is a spherical, acrylic phantom precision-machined to simulate a patient’s
head. It contains known markers and spatial relationships which are detectable by CT,
angiography, and MRI imaging modalities, as well as various therapeutic equipment.
The LUCY 3-D Plus Phantom was developed to simulate clinical situations, verify
hardware and software components, and detect system errors.
LUCY supports all 3-D stereotactic radiotherapy and small field IMRT Systems, for
localization and treatment verification using major commercially available treatment
planning and delivery systems.
Use of the LUCY Phantom permits quantitative assessment and calibration of parameters
described in established quality assurance protocols and the commissioning of new
equipment and procedures, such as fusion and IMRT.
•  Verify planned vs. delivered dose
distribution using radiochromic film,
ion chambers, MOSFETs, TLDS,
and gel
•  Adapts to any stereotactic frame to
verify material or geometry effects
•  A commissioning tool for hardware
and software
•  A useful teaching aid
Detector in open LUCY sphere
Film cassette
Multiple detector cassettes
The LUCY phantom sphere is constructed of acrylic, a standard radiation
calibration material recommended by the AAPM Task Group 21
All screws and plugs are made of white plastic material
A 360° rotation scale is located on the vertical support, around the
sphere axis for sagital or coronal mounting
The LUCY sphere is 140 mm in diameter
Upper Hemisphere Cavity: 81 x 81 x 35 mm, for insertion of an MRI
signal generator or other 3-D volumes, e.g. stacked film or gel
Lower Hemisphere: has four cylindrical chambers 10 mm Ø x 25 mm
deep, for placement of radiological markers
A second cavity of 85 x 85 x 10 mm is located at the center of the
sphere, for placement of accessories and cassettes. An accessory port
of 8 mm in diameter allows for insertion of dosimetry sensors to the
center of the sphere, in the transverse mount
Weight: 11.8 lb (5.3 kg)
