IODOSE DOSIMETRY SYSTEM
The IODOSE dosimetry system was developed by Intelligent Operating Technologies
(IOtech) to provide an automated method of radiation process dosimetry.
The IODOSE system can be easily applied to any radiation dose program which
uses Far West Technology FWT-60 radiochromic film dosimeters. The IODOSE
system includes an automated technique for:
- Dosimeter Batch Acceptance
- Dosimeter Batch Calibration Curve Fitting
- Dosimeter Dose Value Assignment Based on a Simple Power Function
- Simple Dosimetry Worksheet and Process Record Printout
IODOSE eliminates the need for hand-drawn calibration curves, arduous batch
acceptance routines and cumbersome look up tables for dose value assignment.
IODOSE was developed to conform to ASTM standards and meet current AAMI/ISO/ANSI
guidelines.
IODOSE is an automated dosimetry system designed to operate with Far West
Technology FWT-60 radiochromic film dosimeters. Screen formats and printed
forms are easily customized for the user's process and facility application
purposes. IODOSE can also be adopted to use Harwell PMMA dosimeters.
System Features
Templates containing formulae and data transforms have been developed to
allow the user to perform the dose response curve fitting for two dosimetry
wavelengths. The templates provide the means for measuring system variance,
uncertainty, performing dosimeter batch acceptance, fitting the dose response
curves by means of regression, establishing the dose response formulae components
used to calculate and assign the dose, and printing the curve.
System Supplied Items:
User site specific authorization. IOtech proprietary Microsoft Excel templates
with associated instructions and procedures.
Cost and Delivery
$5,000.00 per customer site; 50% due with order: Delivery: 30 days from
date of order. (Does not include cost of site installation, training and
certification which are quoted separately.)
System Description:
- Uses Excel templates to load data and perform data transforms and
calculations.
- Multiple films may be used in each dosimeter. User selectable from
one to five films per dosimeter.
- Full manual input of all process and dosimetry information.
- Capability to accept data via a communications link to a spectrophotometer.
Absorbance readings can be made and processed simply by pressing the Enter
key.
- Dosimetry macros perform either routine measurement or dose map diagrams.
IODOSE CUSTOM INTEGRATION OPTION
Spectrophotometer Integration Capability:
IODOSE was developed to allow direct integration with spectrophotometers
via a serial output. This provides simple electronic integration and eliminates
a source of transposition error. This has been field tested since 1987 and
proven to be an effective means of reducing overall dosimetry error and
improving efficiency in dosimetry reading.
User Specific Requirements:
- Spectrophotometer with serial output port.
- Null modem cable to connect spectrophotometer and computer.
- Communications software program.
IODOSE System Custom Options Available
- Spectrophotometer integration option to provide automated data transfer
directly to the IODOSE system program.
- Product specification database linking and automation macro program
to maintain product or product group historical databases. Process databases
can be automatically updated with process information. Statistical analysis
and quality control charts can be supplied with automated report generation
for user analysis and review.
- Operating manual and on-site training.
Costs for custom options and integration efforts are quoted separately:
