What is the dose area product (DAP)?

The DAP is the result of the multiplication of the entrance dose (air kerma)and the area of the beam. It can be measured by a flat ionization chamberwhich is mounted directly to the light beam housing between the X-rayfocus and the patient surface. Following the inverse square law, the DAPis independent of this distance between focus and patient.This relationship indicates that doubling the distance between a radiationsource and a measuring chamber increases the radiation area by a factorof four, while the dose (air kerma) decreases simultaneously by a factor offour. Both effects cancel out each other. Therefore the dose area productis independent of the distance and it determines in an elegant way allvariable parameters like tube voltage, tube current, filtration, irradiationtime and field size during an examination.

PTW DIAMENTOR systems are setting a worldwide standard

There is no interference with routine work, since the ionization chambers are firmly mounted to the collimator.

The highly transparent ionization chambers ensure proper operation of the light system.

Optimally coordinated components enable convenient and fast installations.

Fast calibration and constancy checks can be performed by means of a built-in test function.

Easy and uncomplicated RIS or HIS connection can be realized straightforward via the RS232 interface.

The user friendly design of the devices ensures easy handling.

Uncomplicated and easy evaluation of the total amount of radiation applied to patients.

For more than 40 years, PTW-Freiburg has worked success-fully in developing and manufacturing DAP meters for dia-gnostic radiology, which are manufactured in line with thestrictest quality standards and completely fulfill therequirements of IEC 60580 and FDA 21 CFR Part 1020.

Application areas:

radiography

fluoroscopy

angiography, DSA, cardiological series

interventional radiography

What are the advantages of a DIAMENTOR system?

[1] Council Directive 97/43/EURATOM of 30 June 1997 on health protection of indi-viduals against the danger of ionizing radiation in relation to medical exposure[2] USA Food and Drug Administration (FDA), Federal Register Part III, Departmentof Health and Human Services – 21 CFR Part 1020 (Electronic Products; Performan-ce Standard for Diagnostic X-Ray Systems and Their Major Components; Final Rule)[3] IEC 60580 Medical electrical equipment – Dose area product meters

The use of radiation in medicine is of great value,but it contributes by far the greatest part of the man-maderadiation dose. Especially diagnostic radiology delivers thehighest share of radiation exposure to the population.

Radiation protection procedures are therefore mandatory in many countries such as the countries of the European Community and the USA. A European Directive requires the“assessment and evaluation of patient doses” [1]. Accordingto a publication of the Food and Drug Administration (FDA)[2], fluoroscopic equipment manufactured on or after June10, 2006, must display at the fluoroscopist’s working positionthe air kerma rate (AKR) and the cumulative air kerma.According to clause 1020.32(k) of this publication, a fluoro-scopic air kerma display device signifies a device that providesthe display of AKR and the cumulative air kerma – such asthe DIADEM patient dosemeter from PTW-Freiburg.

Dose area product (DAP) meters and dosemeters, firmlyinstalled to the X-ray unit, make it possible to determine theradiation load to which patients are exposed during X-rayexaminations. The exposures can be reduced by a measuringdevice informing the practitioner of the total amount ofradiation applied to the patient. Especially high dose andhigh risk X-ray examinations such as fluoroscopy require adevice to determine the radiation exposure to patients.

Measuring devices of the DIAMENTOR series and the DIADEMpatient dosemeter provide for patient dosimetry solutionscovering every application and budget and help to protectpatients against the risk of radiation exposure in medicaldiagnostic radiology.

In 1922, twenty-seven years after Röntgen discovered X-rays, Professor Hammer from the Physics Institute of Freiburg University founded PTW to produce and markethis development of an X-ray dosemeter based on an electrostatic relay, a revolutionary new electromechanicalcomponent for measuring very small electrical charges.

In 1927, Dr. Herbert Pychlau took over the company anddeveloped it during four decades into an internationallyrecognized manufacturer of quality dosemeters for medicalradiology.

During the second half of the 20th Century, the businessgrew into an acknowledged international company, acquiring a good reputation as a pioneer with both scientists and users.

PTW-Freiburg’s production area, which in the very beginning was located in Professor Hammer’s gardenshed, covers a total area of 4000 m2 today. PTW employs a staff of 200 all over the world. The company, which scores steady growth, is the recognized market leader in medical dosimetry today.

We at PTW constantly strive to be competent and reliablepartners for our customers all over the world, which includes maintaining demanding quality standards aswell as comprehensive service and support standards. We will continue our efforts to develop the most reliableand highest quality dosimetry products in the future aswe have in the past, products in which users and patientsput their trust.We are committed to upholding this trust, because weknow what responsibility means.
