QRM-MicroCT-Dose is a dosimetry phantom with

a length of 120mmfor determination of DLP (Dose

Length Product ) and CTDI (Computed

Tomography Dose Index). The central bore hole fits

a standard pencil ionization chamber of 100 mm

length.

The removable insert is commonly used in

standard dosimetry phantoms where ionization

chambers can be inserted at the center and at 10

mmfrom the periphery of the phantom.

The standard Micro-CT phantoms are scaled down

from the diameter of an average human trunk (32

cm) to that of a fat mouse or lean rat (32 mm).

Dimensions other than specified here can be

produced upon request.

Base material ............... tissue-equivalent plastic

Diameter of central bore hole ................. 9 mm

Dimensions for mouse-size phantom:

Diameter ................... 32 mm

Length ..................... 120 mm

Weight ........................ 105 g

Specifications

other hole diameter upon request.
