Stability Study of Ionization Chambers in Standard Mammography Radiation Beams
The ionization chambers are widely utilized in diagnostic radiology quality control and dosimetry. They are simple to use, and can be found commercially in various types depending on their applications. They are the recommended devices for the determination of the beam qualities in mammographic range. To assure the reliability of the measurements, the stability of the response of the ionization...
متن کاملHeavy-Ion Computed Tomography applying a stack of ionization chambers
In particle therapy there are basically two novel lowdose 2D and 3D in-vivo imaging techniques alternative or complementary to Positron-Emission-Tomography (PET) which probe the density matrix in the target volume (Fig. 1): A) As a more indirect probe prompt particle emission during irradiation like emerging secondaries [1], in particular gammas or protons, from the therapeutic beams (Etreatmen...
متن کاملStandard calibration of ionization chambers used in radiation therapy dosimetry and evaluation of uncertainties
Background: Absolute dosimetry of external beam radiotherapy is carried out by the use of ionization chambers. These chambers must be calibrated at a standard dosimetry laboratory before any use in clinical dosimetry. The secondary standard dosimetry laboratory of Iran (SSDL) has the duty of calibrating the ionization chambers used in radiotherapy centers in Iran. Materials and Methods...
متن کاملIonization Chambers for Monitoring in High-IntensityCharged Particle Beams
Radiation-hard ionization chambers were tested using an intense electron beam from the accelerator test facility (ATF) at the Brookhaven National Laboratory (BNL). The detectors were designed to be used as the basic element for monitoring muons in the Main Injector Neutrino beamline (NuMI) at the Fermi National Accelerator Laboratory (FNAL). Measurements of linearity of response, voltage depend...
متن کاملCorrelation Between Tissue Densities in Computed Tomography and Three Different Cone-Beam Computed Tomography Units (In Vitro)
Background and Aim: Bone density is of great assistance in the selection of the proper implant site. The present study aimed to assess the correlation between tissue densities in computed tomography (CT) and three different cone-beam computed tomography (CBCT) units. Materials and Methods: In this descriptive study, a radiographic phantom consisting of a transparent polymethyl methacrylate (PM...
