High impact information on Film Dosimetry

• For the evaluation of beam flatness and penumbra, off-axis ratios at 5 cm depth were measured by film dosimetry using polystyrene phantom [1].
• A dosimetric verification of the treatment procedure was performed with an anthropomorphic phantom: both absolute dose measurements (alanine and thermoluminescent detectors) and relative dose distribution measurements (film dosimetry) have been applied [2].
• The field penumbra width, defined as the mean of the separation between the 20% and 80% isodose lines along the normal of the prescription field edge, was calculated using both the MLC and conventional block film dosimetry and compared [3].
• The effect of the titanium plate on the radiation dose was measured using film dosimetry and soft tissue and bone-equivalent materials [4].
• The authors evaluated the attenuation and scattering properties of coralline hydroxyapatite implants using a 4 MV photon beam and film dosimetry [5].

Associations of Film Dosimetry with chemical compounds

• Results of dosimetry measurements using ionization chambers, lithium fluoride thermoluminescent dosimeters, a scanning scintillation probe, and film dosimetry, confirm theoretical predictions that these sources can deliver dose rates adequate for intracavitary irradiation [6].
• Radiochromic film dosimetry: recommendations of AAPM Radiation Therapy Committee Task Group 55. American Association of Physicists in Medicine [7].
• The detector head consists of a silicon photodiode with filter (Schott glass GG400) and diffuser for visible light measurements and a polysulphone film badge for ultraviolet-B (UVB, 290-320 nm) measurements [8].
• The methods used were (a) a phototherapy (UV-A) radiometer, (b) an electronic integrating dosimeter, (c) indirect spectroradiometry and (d) polysulphone and phenothiazine film badges for UV-B and UV-A respectively [9].
• Also, the wedge angles determined from the MRI ferrous sulphate gel agreed well with the values obtained by using film dosimetry and with calculations by use of TMS (treatment planning system) (Helax, Uppsala, Sweden) [10].

Gene context of Film Dosimetry

• As a result, in the dose range that is commonly used for film dosimetry for IMRT and conventional external beam therapy, the sensitometric curves of EDR2 films cannot be approximated as a linear function, OD = c * D [11].
• The dosimeters used in the measurement included dosimetry film, TLD chips, and rods [12].
• Using ring film-badge dosimeters, scatter radiation to the hands of the operating surgeon was measured during the transvenous insertion of nine permanent pacemakers and one inferior vena cava umbrella [13].
• GAF film dosimetry of a tandem positioned beta-emitting intravascular brachytherapy source train [14].
• In this study we have used a spherical acrylic phantom commercially known as the 'Lucy' phantom (Sandstrom Sandstrom Trade and Technology Inc.) to perform thermoluminiscent as well as film dosimetry for the HNL frame [15].
