深圳灣邊貿(mào)易美國(guó)cirs ct pmma 007 dose phantom ct模體價(jià)格優(yōu)惠 cirs ct模體價(jià)格優(yōu)惠 model 007 007a價(jià)格優(yōu)惠。

廠家：美國(guó)computerized imaging reference systems, incorporated (美國(guó)cirs)

for all computed tomography systems, the food【敏感詞】drug administration recommends measuring the ct dose index (ctdi). each section of the cirs ct dose phantoms can provide separate dose information.  the user can also measure maximum, minimum【敏感詞】mid-range values of the nominal tomographic section thickness when performing dose profile measurements.

each phantom consists of a【敏感詞】of nesting 15 cm thick solid pmma disks measuring 16 cm (head)【敏感詞】32 cm (body) in diameter.  the adult head disk is also suitable for pediatric body measurements. the model 007a includes a third nesting disk measuring 10 cm in diameter for pediatric head measurements. handles on the body【敏感詞】head are provided for ease in handling【敏感詞】maneuverability.

through holes measuring 1.31 cm in diameter will accommodate standard ct probes. acrylic rods are provided to plug the holes when not in use. the acrylic rods are machined to receive 1 mm diameter tld rods.

the model 007 & 007a are manufactured to comply with the fda’s performance standard, 21 cfr 1020.33 that details the measurement requirements. features:

abdominal, adult head, pediatric head configurations

pmma disks【敏感詞】plugs with density of 1.10 g/cc

1.31 cm diameter holes sized for standard ct dose probes

nesting pmma disks minimize storage space compatiblewith all ct scanners

an optional support bracket, model 007-01, can be used to suspend the ct dose phantoms above the imaging couch【敏感詞】align it along the axis of x-ray tube rotation.  this enables the phantom to be used to assess ct dose in helical mode【敏感詞】any mode that requires the extended travel of the imaging couch【敏感詞】a wide beam.  this set-up might be used to address the dosimetry approach described in tg111.  an additional application of the support bracket is to provide a body to simulate continous scatter radiation from the patient during helical ct for dose safety measurements inside【敏感詞】outside the exam room.
