  2. 2. Nuclear Medicine: Introduction Let us introduce ourselves PTW-Freiburg is an internationally operating company, manufacturing and marketing specialized dosimetry and quality control equipment for the medical radiology market. Founded in 1922, the company is located in Freiburg on the western side of the famous Black Forest mountains in southwestern Germany. Our History In 1922, twenty-seven years after Roentgen discovered the X-rays, Professor Hammer from the Physics Institute of Freiburg University founded PTW to produce and market his development of an X-ray dosemeter based on the electrostatic relais, a revolutionary new electromechanical component for measuring very small electrical charges. In 1927, Dr. Herbert Pychlau took over the company and developed it during four decades into an internationally recognized manufacturer of quality dosemeters for medical radiology. PTW has developed and manufactured many generations of up-to-date products over the years, based on the newest technology. The company has grown continuously. Today, 140 employees achieve an annual turnover of 16 Million EUR. A new building has been constructed just recently, which enlarges the total production area to 3,500 m2. Our Operations PTW-Freiburg designs, develops, manufactures and distributes high quality dosimetry and QC equipment mainly for use in the medical field, especially in radiation therapy, diagnostic radiology and nuclear medicine. The development and production of mechanical, electronic and software components are all done in house. We have a well-equipped and modern workshop with 6 CNC machines. Our products, especially the PTW ionization chambers, are well known throughout the world and are recognized for their workmanship and high level of quality. PTW-Freiburg is the market leader in its major product lines. The PTW distribution is organized internationally. A number of exclusive PTW representations are established in many coun- tries around the world. In 1995, the PTW New York Corporation was established to improve our service to customers in America and to distribute and service PTW products all over the American continent. In January 2002, PTW-France was established. PTW-Freiburg runs an accredited secondary standard dosimetry laboratory. We perform radiological calibrations for dosemeters used in radiation therapy, diagnostic radiology and health physics, which are directly traceable to the primary standard. Our calibration lab provides a complete range of radiological calibrations from low X-ray energies up to 60Co and from low to high dose rates. We cooperate closely with official public agencies worldwide, and we participate actively in national and international work groups for the standardization of devices and procedures for dose measurement and quality control in medical radiology. Our Company Philosophy From the very beginning, PTW-Freiburg’s products have been optimized for practicability, precision and quality. All dosemeters are thoroughly tested in radiation beams, and calibration certificates are attached to every dosemeter. Thanks to the constant improvement of our quality standards and internal procedures, our quality assurance system was cer- tified in 1995 as compliant with the standards ISO 9001 and EN 46001. Our medical products are CE marked according to the European Medical Device Directive and they are FDA 510(k) approved. The calibration laboratories are part of the quality management system of PTW-Freiburg. We at PTW-Freiburg are proud to work with our customers as a competent and reliable partner. We provide you with prod- ucts, support and service in line with good manufacturing practice, with the added touch of personal attention from our motivated staff. We constantly strive to improve the international presence and reputation of PTW-Freiburg. We intend to continue our efforts in the future as we did in the past to develop the most useful, most reliable and highest quality dosimetry products possible. Our commitment to maximum customer satisfaction will remain unchanged. For more details please visit our websites at (PTW-Freiburg) and (PTW New York). N-02
