The description focuses on surface matching, continuous monitoring, and comparison to a reference image, which are standard image processing and comparison techniques, not explicitly AI/ML. There is no mention of AI, ML, or related terms like neural networks or deep learning.
No.
The device provides interactive guidance, motion detection, and respiratory gating during radiation therapy. It does not directly treat or prevent a disease or condition, but rather assists in the accurate and safe delivery of radiation therapy.
No
The device is described as a system for patient positioning, motion detection, and respiratory gating during radiation therapy. It provides interactive guidance and monitors patient movement to ensure accurate treatment delivery. While it measures and detects errors, its primary function is not to diagnose medical conditions but to aid in the precise application of a therapeutic intervention (radiation therapy).
No
The device description explicitly states that the Catalyst product consists of "projector unit hardware and Windows based software." It also mentions "two additional units (Catalyst* system without back projection)" which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The Catalyst+ system works by acquiring a 3D image of the patient's surface using near UV light. It then compares this surface image to a reference to guide patient positioning and monitor motion during radiation therapy. It does not analyze any biological specimens.
- Intended Use: The intended use is clearly stated as providing interactive guidance for setup and positioning, intra-fraction motion detection, and respiratory gating during radiation therapy. These are all related to the physical positioning and monitoring of the patient, not the analysis of biological samples.
The device is a medical device used in a clinical setting for patient management during a therapeutic procedure (radiation therapy), but it does not fit the definition of an In Vitro Diagnostic device.

Device Description
The Catalyst product consists of projector unit hardware and Windows based software. The product is intended to be used in radiation therapy clinics for patient positioning, patient monitoring and respiratory gating.
A 3D image of the patient surface can be acquired and compared to a reference image that was either imported from e.g. a treatment planning system, or acquired by surface scanning earlier. The Catalyst system computes the optimal couch correction as well as errors in the patient's posture.
Measurements are done continuously using near UV light (405 nm). The detected errors are in parallel projected using visible light (red and green) in real-time e.g. as a distance map directly on the patient's surface to indicate which body parts that need to be adjusted and how. The rigid-body couch correction is projected numerically and can be sent to the couch control system to enable auto-setup of the couch.
Once that patient is in the correct position, the Catalyst system will continue to monitor the patient during treatment delivery to ensure that it doesn't move out of position. If a large movement is detected, a warning can be issued for the personnel to react on, and/or an interlock can be triggered automatically to shut off the beam.
For optimal coverage of the patient and to support couch kicks, two additional units (Catalyst* system without back projection) can be installed in an angle from the main unit. The configuration is called Catalyst+ HD/PT.
The following application modules are provided:
- cPosition - is the application module that provides a reproducible way of accurately positioning patients. It compares the current patient position with a reference setup bv using surface matching software for calculating adjustments in the patient's position.
- cMotion - is the application module for supervising patient motion during treatment. During treatment the system shall record the patient's position continuously and signal or interrupt treatment when the patient is moving outside specified tolerance intervals.
- cRespiration is the application module for respiratory tracking and gating. ● During treatment the module is able to give a warning or to turn the beam on or off depending on the acquired respiratory signal and on the gating parameters established in the treatment plan. The cRespiration in Catalyst* is based on reference data created in the CT room.

Technological comparison:
The Catalyst* system is substantially equivalent to its predicate device Catalyst (K113276) in terms of intended use and technological characteristics as well as its safety and efficacy profile.
The hardware changes introduced to the Catalyst system consists of the replacement of the old optical 3D scanner devices with new 3D-scanners. The new scanners are based on the same optical 3D scanning technology. The change was driven by an EOL (End of Life) situation of the camera in the old scanner. The supplier and the basic

principle of the scanner (structured light) are unchanged but improvements of primarily the camera has been introduced. To give the Catalyst a more compact and modern look and feel, the scanner chassis have been redesigned. As the new chassis and interior mechanical designs have been well verified and approved to constitute no new risks or decrease in performance.
The c4D software version 6.0.0 is supporting 64-bit architecture. In earlier versions the software was only supporting 32-bit architecture. In c4D 6.0.0 all program components have been compiled for 64-bit architecture. The functionality of the software with respect to the 64-bit support is unchanged. Complete re-verification has been performed to verify that the design outputs meets the design inputs after the change from 32-bit to 64-bit support.
Safety and effectiveness:
Performance data has been submitted to show that the Catalyst system achieves its intended use and that the hardware and software updates raise no new issues of safety or efficacy.
