Intended Use

The Precise Position is intended for use with Philips Incisive CT systems. The following guided workflow. - Patient orientation identification - · Surview range recommendation - · Automatic centering the patient anatomy - · Provide visual images of patient on the table Precise position is indicated for use for CT imaging of the head, chest, abdomen, pelvis, and combination of those anatomies. Patient population limitation: Patient younger than 16 years are not supported.

Device Story

Precise Position is an optional feature for Philips Incisive CT systems to assist patient positioning. A ceiling-mounted camera with color and depth sensing captures images of the patient on the table. Data is transmitted via high-speed fiber/copper hybrid USB cable to the system. An AI algorithm (Convolutional Neural Network) processes input to detect patient joints, orientation, and anatomy center, and recommends surview start/end positions. The system displays visual images of the patient to the operator. Used in hospitals and clinics by radiology staff, the device automates positioning, reducing setup time and improving vertical/horizontal centering accuracy and consistency. It benefits patients by streamlining the workflow and enhancing positioning precision before CT scans.

Clinical Evidence

Clinical evaluation involved 80 scan positions (40 with Precise Position, 40 without) assessed by 5 experts. Results showed up to 23% reduction in patient positioning time, up to 50% increase in vertical (iso)center accuracy, and up to 70% increase in vertical/horizontal positioning consistency. No radiation was delivered to volunteers. Study concluded the device performs as intended with a favorable benefit-risk ratio.

Technological Characteristics

Ceiling-mounted color/depth camera; high-speed fiber/copper hybrid USB connectivity; powered by CT gantry. Software utilizes a Convolutional Neural Network (CNN) for joint detection and anatomy localization. Complies with AAMI/ANSI ES60601-1, IEC 60601-1-2, ISO 14971, and IEC 62304. Operates as an integrated feature of the Philips Incisive CT system.

Indications for Use

Indicated for CT imaging of head, chest, abdomen, pelvis, and combinations thereof. Patient population: adults and children 16 years and older. Contraindications: patients younger than 16 years; decubitus orientations.

| Summary of<br>Clinical Data: | Precise Position is evaluation covered total 80 clinical scan positions in which 40 cases used with Precise Position and another 40 cases without the usage of Precise Position in order to meet the sample size calculation of 40 cases performed average on a CT scanner per day.<br>The thorough clinical evaluation of this feature is done by 5 Clinical experts.<br>The testing did not deliver radiation to volunteers as Precise Position is only for supporting the positioning of the patient for the localization radiograph and therefore “radiation" was not required for those volunteers. |
| | |
| | The clinical evaluation was done with 3 major objectives as follows, |
| | To calculate the time saved per surview planning with and without |
| | Precise Position. |
| | To calculate the accuracy of vertical (iso)center positioning and |
| | Surview (horizontal) start /end position with and without Precise<br>Position |
| | Intra operator consistency in positioning the patient and surview scan<br>range |
| | The summary of clinical evaluation testing was clearly demonstrating<br>the objectives in terms of user benefits as shown below<br>Average Time taken to position without Precise Position and with<br>Precise Position is recorded. Time at user select the patient from<br>Gantry Panel, to time when user pressed Go button from Gantry Panel<br>is measured and concluded that up to 23% time reduction in patient<br>positioning achieved with “Precise Positioning workflow”. |
| | The average offset in mm for vertical (iso) center position among 5<br>operators without Precise Position and with Precise Position is<br>recorded and results shown that with "Precise Position" the vertical<br>position accuracy is increased up to 50%. |
| | Standard deviation in mm for vertical (iso)center positioning &<br>Surview (horizontal) start position among 5 operators without Precise<br>Position and with Precise Position is recorded and results shown up to<br>70% increase in Vertical and horizontal position consistency with<br>Precise Position. |
| | Overall, the Precise Position Clinical Review Report. (Appendix_007)<br>concluded that Philips Incisive CT systems with Precise Position,<br>under normal condition of use, perform as intended, are safe for its<br>intended use and have a favorable benefit-risk ratio. Further clinical<br>investigations are not necessary, as sufficient evidence exists to<br>support these conclusions. |

| | substantial equivalence was demonstrated with non-clinical |
| | performance tests, which complied with the requirements specified in |
