Intended Use

The Veraviewepocs is an extraoral source X-ray unit that is used for dental radiographic examination and diagnosis of teeth, jaw, and oral structure by exposing an X-ray image receptor to ionizing radiation.

Device Story

Veraviewepocs is an extraoral panoramic X-ray unit for dental imaging. System comprises base, support column, patient frame with chin rest/temple stabilizers, C-arm assembly, and remote control box. Operator (dentist, physician, or technician) positions patient within C-arm; initiates exposure via remote button. C-arm rotates around patient head, emitting X-rays toward a cassette containing intensifying screen and film. Device offers standard, pediatric, maxillary sinus, and TMJ quadruple imaging modes with varying magnifications. High-speed mode reduces radiation exposure time by 50% using high-sensitivity intensifying screens. Automatic exposure mode utilizes a sensor to detect X-rays passing through the patient, adjusting tube voltage and current to ensure consistent image density across varying patient sizes. Output is an X-ray film image used for clinical diagnosis of dental and oral structures.

Clinical Evidence

No clinical data. Substantial equivalence is based on technological characteristics and performance comparisons to the predicate device.

Technological Characteristics

Extraoral X-ray system; 184 kg; 235.5 x 100 x 122 cm. Components: C-arm, support column, patient positioning frame. Energy source: Ionizing radiation. Imaging: X-ray film with intensifying screens (e.g., Fuji Grenex HR-12, Kodak Lanex MEDIUM). Modes: High-speed and normal-speed radiographic modes. Automatic exposure control via sensor-based feedback loop adjusting tube voltage and current. Manual and automatic exposure control.

Indications for Use

Indicated for dental radiographic examination and diagnosis of teeth, jaw, and oral structures in patients requiring dental imaging.

Regulatory Classification

Identification

An extraoral source x-ray system is an AC-powered device that produces x-rays and is intended for dental radiographic examination and diagnosis of diseases of the teeth, jaw, and oral structures. The x-ray source (a tube) is located outside the mouth. This generic type of device may include patient and equipment supports and component parts.

Predicate Devices

• Orthopantomograph OP100

#### Intended Use

The Veraviewepocs is an extraoral source X-ray unit that it used for dental radiographic examination and diagnosis of teeth, jaw, and oral structure by exposing an X-ray image receptor to ionizing radiation.

## Technological Characteristics and Substantial Equivalence

The Veraviewepocs includes a base, a support column, a patient frame mounted to the support column, a C-arm assembly, and a control box. The unit weighs approximately 184 kilograms and has dimensions of 235.5 cm (height), 100 cm (width), and 122 cm (depth). The patient frame and the C-arm assembly are mounted to the support column. The control box, which includes operational lights and an emission button, is typically placed in a separate room from the rest of the system. The patient frame includes patient handles for the patient to hold, a chin rest on which to position the patient's head, and temple stabilizers to position the patient's head during the X-ray session. A lip and nose positioner can optionally be used with the chin rest. The C-arm assembly includes a cassette holder to hold an X-ray cassette on one side of the patient's head, an X-ray head on the other side of the patient's head, a Frankfurt plane light beam, a Frankfurt plane light beam knob, a temple stabilizer knob, an image layer light beam, and a control panel. The Frankfurt plane beam, Frankfurt light beam knob, the temple stabilizer knob, and the image layer light beam are used to position the patient's head for optimal X-ray performance. The control panel also is used to position the patient with respect to the Carm. With the patient positioned within the C-arm, the operator leaves the room and uses the emission button mounted to the control box to expose an X-ray. Pressing the emission button causes the C-arm to rotate around the patient's head while the X-ray

head emits X-rays in the direction of the X-ray cassette, which contains an intensifying screen and X-ray film, to expose the X-ray film.

The Veraviewepocs can be used to take standard panoramic images, pediatric panoramic images, maxillary sinus panoramic images, and TMJ quadruple images (i.e., four views of the TMJ, one each of both sides of the mouth with the mouth open and closed). A different button on the control panel is used to set the parameters for that type of image. The standard panoramic images can be magnified at 1.3X or 1.7X. The pediatric panoramic image has a magnification of 1.3X, reduces the X-ray image emission by 10 to 15 percent relative to the standard panoramic image, and reduces the angle of the C-arm's rotation to better coincide with the smaller size of a child's dental arch. The maxillary sinus panoramic image has a magnification of 1.5X and is used to examine the maxillary sinus and facial injuries. The TMJ quadruple image has a magnification of 1.3X and causes the C-arm to rotate twice - once with the patient's mouth open and once with the patient's mouth closed.

The Veraviewepocs operates in either a high speed radiographic mode or a normal speed radiographic mode, and with automatic or manual exposure. Use in the high speed radiographic mode causes the C-arm to rotate approximately twice as fast as many conventional extraoral X-ray source units, such as the Veraviewepocs, while still using conventional exposure rate factors, such as tube voltage and tube current (amperage). The benefit of operating in this mode is that the radiation exposure time is reduced by approximately 50% and the amount of ionizing radiation received by the image receptor, is approximately 50% less than during operation in the normal mode of operation. This mode is made possible by using a conventional high sensitivity intensifying screen, and results in the image density remaining the same as in conventional or normal modes. The intensifying screen fluoresces in response to the X-ray radiation. A high sensitivity intensifying screen merely fluoresces more, relative to a low sensitivity intensifying screen, when exposed to the same level of X-ray radiation. The X-ray film is exposed to the fluorescence from the intensifying screen to impart the image on the film.

One example of a screen and film combination is a combination of a conventional Fuji Photo Film Grenex HR-12 Intensifying Screen with conventional Kodak T-Mat G film. The Veraviewepocs also can be operated in the normal speed mode and use a normal speed radiographic screens, such as the Kodak Lanex MEDIUM.

When used in the automatic exposure mode, the X-rays passing through the patient are detected by a sensor. The device uses the signal received to control the tube voltage and current with respect to the speed of the film's movement. The objective of operating in this mode is to ensure a high quality image with a consistent level of density for patients varying in size from small children to large adults.

The Veraviewepocs is substantially equivalent to Instrumentarium Corporation Imaging Division's Orthopantomograph OP100 ("OP100"). The Veraviewepocs and its predicate device are both panoramic X-ray units. The Veraviewepocs is substantially equivalent to the OP100 because both devices have the same general intended use, and similar technological characteristics and operating principles. Specifically, the intended use of

the Veraviewepocs is for dental radiographic examination of teeth, jaw, and oral structures by exposing an X-ray image receptor to ionizing radiation. The Veraviewepocs is intended to be operated by physicians, dentists, and X-ray technicians. The intended use of the OP100 is for producing diagnostic X-ray radiographs of dentition, TM-joints, and skull, and has an ortho trans option for producing crosssectional and lateral images of the dental arch using linear tomographic methods. Although the wording of the two intended uses is not word-for-word the same, the general intended use is the same.

The principal differences in the technological characteristics between the Veraviewepocs and the OP100 are: (1) the availability of operation of the Veraviewepocs at a high speed radiograph mode and the resulting differences in exposure time; (2) the availability of the preprogrammed exposure control on the OP100, which is not available on the Veraviewepocs; (3) the differences in nominal magnifications available to the operator: and (4) the unavailability of the TMJ postero anterior mode on the Veraviewepocs. These differences do not raise any new issues of safety or effectiveness. As such, the Veraviewepocs raises no new issues of safety or effectiveness.
