Identification of the Devices: ruentification of the Devices. Proprietary-Trade Name: "Pulmoscan," "Uniscan," and "Pulmoscan-T" Digital Radiographic Systems Classification Name: Stationary X-Ray System, Product Code KPR and MKP Common/Usual Name: Stationary or Transportable X-Ray System - 2. Equivalent legally marketed devices This product is similar in function to the Siemens Multix FD and Thorax FD Stationary X-Ray System (K983732) - 3. Indications for Use (intended use) The "Uniscan" model is a stationary general-purpose diagnostic (universal) system for obtaining standard planar X-ray images of the bone structure and soft tissues of a patient in the standing, sitting and lying position . and Tyng Position : - The "Pulmoscan" model is a stationary specialized-purpose diagnostic system for mass examination (screening) of wide groups of population, first of all, in polyclinics at the stage of before-doctor examination with the purpose of early diagnostics of the thorax organs. Giagnostics of the thorax organs. - The "Pulmoscan-T" model is a mobile specialized-purpose diagnostic system, particularly, for mass examination (screening) of wide groups of population directly at the places of their maximum concentration (in educational institutions and at cnterprises), in remote areas (villages, military units), in institutions with the special access regime (refugees camps, penal jurisdiction) with the purpose of early diagnostics of the thorax organs. - 4. Description of the Device: The principal of functioning of the DRS system is based on: - generation of highly stable low-energy X-ray radiation (from 40 up to 150 keV) with controllable parameters (voltage, current, time, exposure duration) by means of an X-ray source connected to the X-ray power supply unit; - formation of a flat narrow with the width D fan-shaped X-ray beam with the possibility of masking according to the radiation angle a by means of the adiustable diaphragm; adgustere of the area of the patient's body to be examined (input dimensions A B) by scanning with a flat X-ray beam in the field of the scanning angle b with the possibility of specifying and visual control of the scanning (exposure) field; - magnification of the planar X-ray image of the patient with the specified enlargement by projecting it to the scanning X-ray detector located at a {1}------------------------------------------------ K0 33577 considerable distance from the patient; - obtaining the digital X-ray image of the area to be examined by means of the scanning X-ray detector (on the basis of a linear matrix multiclement semiconductor detector), converting the absorbed X-ray radiation into digital form; - formation of the two-dimensional digital projection image on the computer monitor with the possibility of manipulation and archiving by means of the special software - 5. Safety and Effectiveness, comparison to predicate device. The results of bench and user testing indicates that the new device is as safe and effective as the predicate devices. | Characteristic | Siemens Multix FD and<br>Thorax FD Stationary | "Pulmoscan," "Uniscan,"<br>and "Pulmoscan-T" | |----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------| | | X-Ray System<br>(K983732) | Radiographic Systems | | Intended Use: | Intended for use by a<br>qualified/trained doctor or<br>technician on both adult and<br>pediatric subjects for taking<br>diagnostic radiographic<br>exposures of the skull, spinal<br>column, chest, abdomen,<br>extremities, and other body<br>parts.

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of {3}------------------------------------------------ medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 796-5450.
