Dose Area Product Measuring System VacuDAP

VacuDAP systems - patient safety by Dose Area Product monitoring

The European Guideline 97/43/EURATOM requires the determination of the patient dose in X-ray applications especially with children and when using higher doses. The VacuDAP system for automatic measuring of the dose area product complies fully with this requirement. (IEC 60580)

The modular VacuDAP dose area product measuring system offers various ionization chambers and configurations for a wide range of X-ray equipment. The VacuDAP measuring system is used to measure the Dose Area Product (DAP). This value is most suitable to indicate the patient dose in X-ray diagnostics.

The transparent ionization chambers fit easily into the accessory rails at the collimator. Adapted circular ionization chambers are used for complete integration into C-arm machines. All devices are equipped with a serial interface for transfer data files to a printer or a PC. Different printer, adaptor and PC software is available as an accessory.

VacuDAP systems - patient safety by Dose Area Product and Air kerma monitoring

The system VacuDAP duo allows to determine Dose Area Product, Dose Area Product Rate, Air Kerma, Air Kerma Rate and irradiation time.

So the system fully complies with international regulations for Patient Dosimetry in radiography and fluoroscopy systems (IEC 60601-2-54, IEC 60601-2-43, 21 CFR 1020.32, IEC 60580).

 

Radiation Measuring Technology in Medicine

Minimizing the radiation risk

VacuTec has specialized in the development and production of up-to-date measuring equipment for determining radiation doses in the medical sector. Today, diagnostic radiology is a main factor of the populations exposure to radiation. Therefore, major importance must be attached in modern radiation protection to minimize radiation doses while ensuring an optimum image quality at the same time.

X-ray Diagnostic Process

VacuTec gives particular attention to the development and manufacture of ionization chambers for the application as detectors in diagnostic X-ray apparatus. Ionization chambers for automatic X-ray exposure units (AEC Sensor) are used as sensor elements of the automatic exposure control function. They are situated in the optical path directly in front of the film cartridge or an image receiver. A charge equivalent to the dose is generated in the measuring chamber and a corresponding cut-off signal is created, thus ensuring a reproducible optimum film density or dose independent of the beam quality, object density and other factors. The ionization chamber of the VacuDAP dose area product measuring system attached to the collimator can detect the entire radiation load that the patient is exposed to during the X-ray diagnostic process.

Nuclear Medicine

Among the further features offered by VacuTec are several Ionization Chambers for Isotope Calibrators for determining the activity of radiopharmaceuticals in nuclear medicine.
