美國(guó)CIRS 731-HN頭部模體產(chǎn)品簡(jiǎn)介：
The CIRS Proton Therapy Dosimetry Head is an anthropomorphic head phantom
designed for commissioning and treatment planning system (TPS) verification with
any conformal or IMRT Proton Therapy system1.
The phantom is constructed of CIRS tissue-equivalent materials, which mimic
reference tissues within 1.5% for protons and within 1% for photons from 50 KeV
to 15 MeV. The Proton Therapy Head can be used during all standard IMRT
procedures from CT image acquisition to proton beam delivery
verification1,3.
Tissue equivalency of detailed internal structures makes the phantom ideal
for treatment plan evaluation in high density-gradient locations, which are
specifically important in proton therapy2, such as air cavity vs. bone
structures. Internal structures include brain, bone with cortical and trabecular
distinction, larynx, trachea, fully-open sinus cavities, nasal and mouth
cavities, and teeth with distinct dentine, enamel and root structure.
Model 731-HN approximates the average male human head in both size and
structure to allow for intuitive set up with any patient positioning or fixation
device.
One half of the phantom is sectioned in 2cm increments for three film
locations in the cranio-caudal direction starting from the approximate center of
the sagittal plane. Because slices are orthogonal to the CT axial plane,
artifacts caused by residual air gaps are noticeably reduced compared to
standard axial slices.
Proton system commissioning is enhanced by placement of a tungsten BB in a
molar and a titanium prosthesis attached by two screws at C3 and C5
vertebra.
