No
The description mentions "pattern recognition techniques" for determining position, which is a form of image processing, but does not explicitly state or imply the use of AI or ML algorithms for this or any other function. The core function is described as calculating translations based on user-aligned overlays of ultrasound and CT data.
No.
The device is for patient positioning and tumor localization prior to radiation therapy delivery, not for treating diseases or conditions directly.
No
The device is a patient positioning system that uses ultrasound images and pattern recognition to confirm the location of target organs or tumors for accurate radiation therapy delivery. It provides alignment information and assists in repositioning, but it does not diagnose medical conditions.
No
The device description explicitly mentions hardware components like a camera, an ultrasound transducer body, and a custom "clamshell" that are part of the I-Beam system. It also describes the system receiving a signal from the camera. While it uses software for image processing and calculations, it is not solely software.
Based on the provided information, the I-Beam device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The I-Beam system directly interacts with the patient using ultrasound and camera technology to determine the position of internal organs or tumors. It does not analyze biological samples like blood, urine, or tissue in a laboratory setting.
- The intended use and device description clearly focus on patient positioning for radiation therapy. The system uses imaging data (ultrasound and CT) to guide the physical movement of the patient, not to diagnose a disease or condition based on the analysis of a biological specimen.
- The device description details the use of ultrasound and camera technology to determine spatial relationships. This is a form of medical imaging and positioning, not in vitro testing.
Therefore, the I-Beam device falls under the category of medical devices used for imaging and patient positioning, not in vitro diagnostics.

Intended Use / Indications for Use
I-Beam is a self-contained mobile patient positioning system that uses real time ultrasound images of patient target organs or tumors while the patient is positioned on the couch of the linear accelerator to confirm the location of these patient target organs or tumors prior to delivery of external beam radiation therapy.

Device Description
The I-Beam Patient Positioning System provides a method for a hospital/clinic to accurately position a patient prior to delivery of external beam radiation therapy each day such that the patient tumor volume on the day of therapy coincides with the tumor volume from the treatment plan. Patient positioning may be necessary because of day-to-day movement of the soft tissue target within the patient. Closer alignment assures proper tumor coverage and a minimum of dose to healthy tissue and structures surrounding the target.
I-Beam achieves this alignment by having a camera provide a signal to I-Beam. The camera is attached to an ultrasound transducer body by use of a custom "clamshell" in an orientation that points the camera in a direction 180 degrees from the plane of the transducer output. As the transducer ultrasound system (not part of I-Beam) images the patient target, the camera is looking up at a targeting grid located on the shadow tray of the linear accelerator. Using pattern recognition techniques, the I-Beam system is able to determine the position of the isocenter of the target volume relative to the isocenter of the linear accelerator. The user then superimposes the ultrasound tumor volume data obtained from this scan on that from the original treatment plan data input to I-Beam earlier. This treatment plan is based on a CT study set, and the user aligns the two tumor volumes by "moving" one relative to the other. I-Beam senses this relative movement of the ultrasound tumor volume to that from the treatment plan and converts that into a three axis "translation" figure which gives the operator the amount and direction the patient must be moved in each axis to achieve alignment with the treatment plan and thus the linear accelerator. Correct re-positioning of the patient is verified by performing a second ultrasound scan of the patient and overlaying that with the original CT-based treatment plan tumor volume information. The translation figures will advise the user of any remaining misalignment should there have been a misinterpretation of the translation date and/or patient positioning.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Summary of Clinical Testing: Actual testing in a clinic was not performed as part of the development of this feature. Clinical testing is not required to demonstrate substantial equivalence or safety and effectiveness of the device.
Summary of Non-Clinical Testing: Both verification and validation test cases were written and executed to assure the system is correctly measuring patient tumor volume shift as well as outputting correct patient "translation" to achieve alignment of planned versus actual patient tumor volume. This testing also verified correct operation of the optical alignment target and the camera and the ability of I-Beam to convert this information into clinically correct patient repositioning information.

Device Intended Use: I-Beam is a self-contained mobile patient positioning system that uses real time ultrasound images of patient target organs or tumors while the patient is positioned on the couch of the linear accelerator to confirm the location of these patient target organs or tumors prior to delivery of external beam radiation therapy.
Summary of Technological Characteristics Compared to Predicate Devices: The predicate devices can both use ultrasound imaging of the target volume on the day of treatment to determine the amount of target movement relative to the original treatment plan data and provide the user feedback on correct patient positioning for that day's therapy.
ExacTrac outputs the automatic couch movement in three dimensions necessary to reposition the tumor volume. BAT has an interface to the treatment couch to determine when the necessary patient movement to achieve alignment has been performed. I-Beam outputs the direction and amount of patient movement to achieve alignment onto the system display and this is verified during a second patient scan after repositioning.
