The unit is not intended to treat, prevent, cure, mitigate or otherwise medicate ailments.

## Device Story

Mobile X-ray unit (Compact/Comp-X) provides diagnostic imaging in hospitals/clinics; used where stationary units are unsuitable. Operator (technician/physician) positions unit via wheeled base and articulated arm (45-inch extension, ±90-degree pivot, ±180-degree gimbals). System uses X-ray tube with rotating anode (40-120 kVp) and Beam Limiting Device (BLD). Operator selects kVp/mAs settings; two-step push-button initiates 'prep' (filament warming, anode spinning at 3000rpm) followed by high-voltage exposure. Inverter transforms mains current to high-frequency, medium-voltage, then to high-voltage via monoblock generator. Controller monitors parameters; aborts exposure if errors occur or if button released. Provides radiological exposure on film/receptor to aid diagnosis of fractures/illnesses. Benefits include portability for remote/bedside imaging.

## Clinical Evidence

Bench testing only. No clinical data provided.

#### Summary of the safety and effectiveness information in the premarket notification (510(k) Summary)

DEC 1 2 1997

Submitted by: Eurotec, srl Address: Via Aldo Moro 5/7, 24020 Scanzorosciate (Bergamo) Italy Telephone: (++39.35) 655-557 Contact Person: Christian Bonazzi (Official Correspondent, Technical Director of Electronic Design Department) 510(k) Number: K972365 Owner Operator ID Number: 9030797

This Summary was prepared on August 23, 1997

(1) This 510(k) summary is part of the premarket notification documentation for the unit "Compact" or "Comp-X", an X-ray mobile unit intended to be moved in a hospital or clinic or other facility to provide capability of X-ray exposures in remote areas, or in instances where stationary devices are unsuitable. Its classification name is X-ray mobile unit (RAD only). Its classification number is IZK.

(2) The device for which this 510(k) Summary is prepared is substantially equivalent to the model MU125, manufactured by Shimadzu (510(k) number: K955036) . This device was found to be substantially equivalent through the 510(k) premarket notification process.

(3) The device that is subject to this 510(k) premarket notification document will be labeled on all promotional material and within all documents as "X-ray mobile unit with HF generator". The device appears as a mobile unit and is composed of three parts:

The X-ray generator (monoblock) is constituted of an X-ray tube with rotating anode, encased in metal casing which also contains the high voltage generator. High voltage is required by the X-ray tube to generate a usable X-ray beam. The X-ray tube emits radiations when supplied with between 40,000 and 120,000 Volts. The monoblock is attached in a non-permanent manner to a Beam Limiting Device (BLD), which will limit the X-ray beam exiting the window of the monoblock by means of adjustable shutters. The combination of monoblock and BLD create the X-ray source.

The monoblock and the X-ray emission are controlled by an X-ray controller an electronic device connected to the monoblock through low tension cables.

X-ray generator and X-ray controller are enclosed in mechanics which allow the device to be moved on wheels, as well as the X-ray generator to be positioned as required by the operator.

The material used are metal and radiation insulating material (lead (Pb() for the X-ray head (monoblock and BLD). The mechanics are constructed of zinc coated metal.

{1}------------------------------------------------

The device is designed to be transported on wheels: the main structure contains the electronics and sits on a triangular base with two set of wheels; two larger wheels are located at the rear of the base, while two smaller wheel (nose gear) are located at the front of the device. The top of the main structure is equipped with a column (perpendicular to the ground), which supports the arm structure; this (at the end of which is located the X-ray source) extends for 45 inches and allows vertical movements (up and down) and pivotal movements. The latter is achieved by moving the arm around its column for a total of ±90 degrees.

The X-ray source is attached to the arm by mean of gimbals, which allow z-axis rotation and x-axis rotation for a total of ±180 degrees each.

The BLD is also capable of movements, swiveling on its vertical axis for a total of ±90 degrees.

The device is designed to perform X-ray exposures by means of a two-step push button (attached to the unit by mean of a 13ft coiled cord). The operator chooses the preferred setting by selecting kVp (ranging from 40 to 120) and the mAs (ranging from 0.5 to 100). After selecting the appropriate settings and positioning the device, the operator will initiate exposure by 'prepping' the exposure. This is achieved by pressing the first step of the push button. This step will feed the appropriate mA (current) to the filament of the tube, thus warming it, and will begin spinning the anode at 3000rpm At this stage, however, there is no radiation emission, since the tube is not fed with high voltage current. Emission will begin once the unit has prepped, and will prompt (by means of a led located on the control panel) the operator to push the second step of the push-button. At this point, the current drawn from the mains and stored by capacitors will be released in one-350 Vac shot, which will be directed to the electronics and processed by an Inverter. The inverter fulfills the duty of transforming this current in High Frequency 350 Vac shot, which will be directed in this form and fed to the monoblock. This high frequency, medium-voltage current is transformed to high voltage current through a HV generator located in the monoblock. The generator will create the high voltage technique (40 to 120 kVp) set by the operator. Only after the HV reaches this point (and after all settings and parameters have been controlled and stabilized by the X-ray controller on their way to the tube) the tube emits its radiation is emitted for a time which varies, according to the technique pre-set by the operator, between 5 milliseconds and 4 seconds.

Any problem encountered during the control by the X-ray controller, will result in an abortion of the exposure and an indication (both visual and audible) of such action.

Any exposure can also be manually aborted by the operator by releasing the push-button before the emission is terminated. This action will also result in an audible and visual signal to the operator.

After an exposure is terminated, the operator can perform another exposure after 8 to 10 seconds.

#### (4) INTENDED USE STATEMENT

The device is intended to be moved in a hospital or clinic or other facility to provide capability of X-ray exposures in remote areas, or in instances where stationary devices are unsuitable. The device is designed to be used in conjunction with a cassette film or other image receptor, in order to provide a radiological exposure of the human body, to serve as an aide in diagnosing illnesses and fractures. The unit is not intended to treat, prevent, cure, mitigate or otherwise medicate ailments.

(5) In brief, the device has the same technological characteristics and uses as the predicate devices stated in paragraph (2) of this Summary, in that all devices referenced in paragraph (2) are X-ray mobile units, which move on wheels, composed of a main structure, containing electronics for the control of the radiographic exposures, used within hospitals or other structures to provide capability of radiographic exposures used in the diagnosis of ailments. Furthermore, all predicate devices are furnished with an Xray head, a high tension transformer to supply the tube with the necessary high tension, and a BLD to limit the projection of the X-ray beam as well as to give a visual indication of the area where the beam is going to be projected. These devices might, however, present some minor differences. These differences might be:

- k Vp range: might slightly vary from device to device I.
- II. focal spot: might vary from device to device depending on the maximum kW output of the unit
- III. mAs range: might vary from device to device
- IV. Shortest exposure time: might vary depending on the technique settings range of a specific device
- V. motorized movements: some devices might have motorized movements in light of their weight
- VI. operating frequency: some devices might operate on low frequency, which implies a lower quality image and longer X-ray emission
- VII.mechanical movements: some devices might be equipped with mechanical movements that differ from other devices (i.e. telescopic movement of the Xray head).
