Table 1. The Exradin A1SL type with an applied polarizing voltage of 150 V was chosen as an LNE-LNHB reference chamber type in 2 × 2cm2 radiation fields. There is interest in the variation of the response of an ionization chamber with a high-Z electrode in high-energy photon beams as these chambers are often used for relative dosimetry. Iba ® CC01, Iba ® CC04, Iba ® CC13 ion chambers placed at a depth of 5cm in solid phantom (RW3). Also we scanned this phantom with ion chambers by Siemens ® Biograph mCT. PTW, Exradin A14SL and Exradin A16 do not. (Some figures in this article are in colour only in the electronic version) 1 Former student interns at LNHB. 30002 w/cap CV50-2 … Parameters of cc13 and cc01 Ion chambers. This phantom and chamber were positioned using room lasers and the accelerator crosser as can be seen in Figure 1. To investigate this, P The IBA Compact Chamber CC01 cylindrical ionization chamber was inserted into the center of the phantom in parallel to the beam plane. CC01 IBA CC01 0.01 cm3 Micro chamber Exradin A12 0 6 cm3 A12. Only three types of chambers were deemed suitable as reference chambers according to LNE-LNHB requirements and specifications from McEwen (2010 Med. AccessGUDID - CC01 Ion chamber (EIBADS050000)- CC01 Ion chamber: 0.01 ccm, for stereotactic, IMRT and any small field measurements, TNC triax (not recommended for use in absolute dosimetry due to small volume) the IBA CC01 chamber to test the effects of a reduction by a factor of 10 and confirmed that the results are not affected. C I R S I DS I (IS) C R M DOSIMETER CAVITY CODES Manufacturers Model # CIRS CV # Availability (Model # or Series) PTW (Cont.) 2 IBA DOSIMETRY ABSOLUTE DOSIMETRY Air Ionization Chambers ... CC01 and CC04 CC01 and CC04 are the conventional ionization chambers for measurements of small fields and of ... CC13 is the standard chamber for clinical use in water phantoms and for output factor measurements. (2) IBA CC01, IBA CC04 and Exradin A1SL show a proper response as a function of applied voltage for both polarities. Sensitivity of cc13 is 3.8 × 10−9 C/Gy and of cc01is 4× 10−10 C/Gy. The smallest-volume chamber (IBA CC01) had the smallest correction followed by the other micro chambers Exradin-A14 and A14SL. IBA CC01 (1/3). Some parameters of these two ion chambers are given in Table 1 below [1] [7]. A COMPARISON OF COMPACT IONIZATION CHAMBER PERFORMANCE AND RELATIVE READINGS Abstract approved: Kathryn A. Higley . Phys. The equivalent square fields sizes were found to be 3.6 cm and 4.8 cm for the 10×2 cm 2 and 10 × 3 cm 2 field sizes respectively. Manufacturer Specifications - CC01, Scanditronix Wellhoefer Please note: None of the equipment posted for sale on MedWOW.com is owned by MedWOW, should you have any questions regarding a specific item, please direct them to the appropriate seller by making use of the available communication channels on the items page. QA plans were prepared by transferring twenty five patient plans to phantom assemblies for three ion chambers. ionization chambers cc13 (IBA company) with active volume 0.13cm3 and cc01 (IBA company) with active volume 0.01 cm3 are used. IBA cc01 ion chamber: 10.0: 2.0: 3.60: Gafchromic EBT3 film was cut into pieces and placed between slabs of Gammex Solid Water Type 457 – …
