DEVICE DESCRIPTION The device is represented by a software computer program installed on regular computers. The device has two types of users: a web and a local user. The web user submits an image set for processing to the local user via internet to the device's database. The local user is viewing the images of the image set, process the image set and sends a PDF report with calculations for the web user. #### Workflow details Working a mage is transferred to the device database by a web user. An operator (a local user) then uses a workstation to analyze AOMSI and generate a PDF (a look abol ations, which is then available for viewing on the web for the web user. The local user/operator/server is installed at only one core location and X-ray images from different users are sent to the location for analyses. The device is primarily intended for viewing digital spinal X-ray images and to prepare analyses of alteration of motion segment integrity (AOMSI). ### Automated part of the reporting process - 1. Automatic limitation of points placed respective to the number of vertebras - 2. Automation of 4th point positioning. - 3. Automatic mathematical calculations - 3. Automatic notice to calibrate an image upon placement of first point on an image in image editor window - 5. Automation of notification of an improper order of points - 6. Automatic user password retrieval - 7. Automatic submission of PDF report via e-mail to the web user ### What is needed to perform the analysis? {2}------------------------------------------------ #### Page 3 of 11 #### Traditional 510 (k) Submission ### Submission Date: K092427 3/2/2010 - 1. The analyses are to be performed only by a licensed medical practitioner who is knowledgeable of specific spinal anatomy and specific protocols for image analysis - 2. Medical Device Spinal Guides PACS - Spinal pure lateral X-ray views in flexion and extension taken with the calibrator 3. in place - 4. Computer hardware - 5. Internet with enough available speed #### Processing For all square vertebras the first point (I) is placed on the superior anterior external line angle of the vertebral body. For all square vertebras the second point (II) is placed on the superior posterior external line angle of the vertebral body. For all square vertebras the third point (III) is placed on the inferior posterior external line angle of the vertebral body. For all square vertebras the forth point is computer generated. The 4th point (IV) is placed to the location to make the inferior side of the figure equal and parallel to the same of the upper. For the vertebra without vertebral body (C1) the point locations are as follows: - The first point is placed on the Superior Anterior External Line 1. Angle formed by dens of C2 and the most proximal point to it on C1 {3}------------------------------------------------ #### Page 4 of 11 Traditional 510 (k) Submission ## Submission Date: K092427 3/2/2010 The second point is placed on the Superior Posterior Internal Line 2. Angle formed by radiographic laminar-pedicle junction of C1 and the superior border of C1 at the end point of that junction The third point is placed on the Inferior Posterior Internal Line 3. Angle formed radiographically by laminar-pedicle junction of C1 and the inferior border of C1 at the very end point of that junction. The forth point is computer generated, as described above For triangular vertebra (C2): The first point is placed on the Inferior Anterior External Line 4. Angle of the vertebral body. The second point is placed on the Inferior Posterior External Line 5. Angle of the vertebral body. The third point is placed on the next Superior Posterior External 6. Line Angle formed between transverse processus of C2 and the dens of C2 vertebrae > 7. The forth point is computer generated {4}------------------------------------------------ ### Page 5 of 11 ### Traditional 510 (k) Submission ## Submission Date: K092427 3/2/2010 Once the third point is placed, the fourth one is generated by a computer. The fourth point is placed to complete a proper quadrangle to form square, parallelogram or rhombus. The fourth point is placed by a computer to make the lower side equal and parallel to the upper side and the opposing internal line angles equal to each other. Measuring Before placement of points the local user has to calibrate the image. Once we have placed the points we can relate them to each other by calculating degrees of their planes. After the points are placed and proper geometrical figures are created the device will measure relative metric discrepancies. The device measures relative angulation as well as specific metric relationship of shifts in millimeters and in percentages relative specific points. Then, the data is compared with known norms and abnormalities respective to the specific points and spinal parts. Significance of the study In order to treat the patient better, estimate prognosis of the patient's condition and quantify the patient's impairment due to damages to the spine the AMA published certain criteria by which a doctor has to formulate a diagnosis 5 of 11 {5}------------------------------------------------ #### Page 6 of 11 Traditional 510 (k) Submission ### Submission Date: K092427 3/2/2010 and treatment plan, as well as quantify the patient's permanent impairment rating. The last edition, the 6th Edition of AMA published in 2008 specific limitations in norm and abnormalities for spinal evaluations of alteration of motion segment integrity calculations. Using computerized technology installed within the device a doctor can spend almost no time in completion of otherwise lengthy mathematical calculations and get precise diagnostic report ready to apply for the best patient's care. Once specific measurements of relationship of one vertebra to another are obtained, they are compared to norms and abnormalities. The patient will be treated better and treatments will get better outcomes. The individual and third party payers will save money when treatments are not indicated. The device does not read pathologies. It is an AOMSI (alteration of motion segment integrity) specific. #### Quality control functionality If the order of the points placed are not followed the above protocol (not as 1, 2, 1. 3, but 1, 3, 2) the 4th point will be placed away from the field of the column by the computer making the operator aware of the error made. 6 of 11 {6}------------------------------------------------ ### Page 7 of 11 Traditional 510 (k) Submission 2. 3. # Submission Date: K092427 3/2/2010 The error figure will be seen by the local user immediately during processing. No points can be placed on an image without prior calibration > X-ray images have to be taken with the calibrator, a small quadrangular metal plate with known dimensions. The calibrator will be affixed on the patient's skin in the designated area with the help of special, made out of paper, holder. The holder will position the metal plate vertically. The plate will be shown on an image as a quadrangle. A local user (operator) will be adjusting the image's size according to the calibrator's image and its known dimensions. The image set will be reviewed for quality before the processing can be done. If images sent are not in the appropriate quality, the image set will be rejected by the local user. The web user will see the specific image set rejected and why and will consider for a resubmission a better quality image 4. 7 of 11 {7}------------------------------------------------ ### Page 8 of 11 Traditional 510 (k) Submission న. # Submission Date: K092427 #### 3/2/2010 Buttons: 1) "Undo"- returns to the previous state, 2) "Zoom In"- increases the image in size, 3) "Zoom Out"- decreases the image in size, 4) "Reset to Original"- returns the image to the original size, 5) "Trace Image" guides the operator through the processing of the image 6) "Test Points" retrieves the points from the database on the processed image from the database The architecture of the device is represented by the following diagram: {8}------------------------------------------------ Page 9 of 11 Image /page/8/Figure/2 description: This image shows a diagram of a traditional 510(k) submission process.

INTENDED USE ー、 Spinal Guides PACS is intended to perform: operations relating to the acceptance of spinal X-ray medical images and patient demographic information, their display, digital processing, review and editing, measurements report generation with respective storage and teleradiology exchange capabilities. They are intended to be used by a physician to view the images and use as an aid in calculation of alteration of motion segment integrity (AOMSI) of human spine. This device is not intended to be used for mammography images and does not require usage of 5 Mega pixel monitors. # D. SUBSTANTIAL EQUIVALENCE SUMMARY "Spinal Guides" PACS has substantially same indications for use as the legally marketed predicate device Opal-Rad manufactured by Viztek, Inc., K063337 with major differences being: - 1. It does not process images for mammography and does not require 5M pixel monitors, nor does it display 3D images acquired from CT and MR modalities. - 2. It was created in C# computer language - 3. Spinal Guides PACS were specifically made viewing of the images and for calculation of Alteration of Motion Segment Integrity (AOMS) of human spine. This indication difference does not modify the intended use- to assist users performing quantifications and qualifications common to the general medicine, orthopedic, radiologic, and chiropractic specialty. The new device has substantially the same control methods and operating principles as the predicate (both are computer systems and software installed in them, both intended for viewing of images) with the following major differences: - 1. Images for Spinal Guides are to be taken with the calibrator affixed on the patient's skin - Web users are opening the images and enter all required demographic information 2. and complete an image set for submission to database in "Pending" status - 3. Local users are able to open image sets and view the images as well as process the images using automatic calculation process and formulate a PDF report turning "In process" and "Waiting for Completion" and "Complete", or turn the image sets into "Reject" to reject the image set. {10}------------------------------------------------ #### Page 11 of 11 Traditional 510 (k) Submission ### Submission Date: K092427 .3/2/2010 - 4. Once the image set turned to "Complete" by the local user the PDF report is automatically available to the web user Descriptive characteristics and data provided in this submission are sufficiently precise, to the best of our knowledge, to assure substantial equivalence. # E. TECHNOLOGICAL CHARACTERISTICS Both the new device and the predicate are software applications installed on standard computers and servers, and utilize teleradiology via internet. The technological characteristics are substantially the same in the proposed and predicate devices, with major differences are as follows: - 1. Visual Studio 3.5.net C# programming language - 2. The new device does not require usage of 5 megapixel monitors since the application is not intended to use mammography images #### F. TESTING Nonclinical tests for Spinal Guides PACS (software verification and validation) have been performed in conformance to specifications and the application is in conformance to DICOM standard PS3 NEMA 3.0 1/1/2008 #### G.
