The description focuses on mechanical control and sequential processing of leaf positions based on pre-defined treatment plans, with no mention of learning, adaptation, or complex pattern recognition characteristic of AI/ML.
No.
The device is described as a "Micro Multi Leaf Collimating (MMLC) system" that assists in the delivery of radiation and shapes the Linac beam, meaning it is a tool used in a therapeutic procedure rather than a therapeutic device itself.
No
The device is described as a "LINAC based Micro-Multi-Leaf-Collimator (MMLC), used in radiation treatment" which aims to assist in the "delivery of radiation." It shapes the Linac beam and positions leaves for treatment, but it does not diagnose medical conditions.
No
The device description explicitly states that DART-12 is composed of hardware components including the MMLC module, the Linac interface module, and the Distribution module, in addition to the Workstation with DART-12 Control Software.
Based on the provided information, the DART-12 device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that DART-12 is "intended to assist the radiation oncologist in the delivery of radiation to well defined target volumes while sparing surrounding normal tissue and critical organs from excess radiation." This describes a device used in the treatment of a patient, specifically in radiation therapy.
- Device Description: The description details a "LINAC based Micro-Multi-Leaf-Collimator (MMLC), used in radiation treatment." It describes how it shapes the radiation beam and operates in conjunction with other radiation therapy equipment.
- Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The DART-12 does not interact with patient specimens in this way. Its function is to physically shape a radiation beam directed at the patient's body.
In summary, DART-12 is a medical device used in radiation therapy for treatment delivery, not for in vitro diagnostic testing.

DART-12 is intended to assist the radiation oncologist in the delivery of radiation to well defined target volumes while sparing surrounding normal tissue and critical organs from excess radiation.
DART-12 is a tertiary Micro Multi Leaf Collimating (MMLC) system. It performs the same functions as beam shaping blocks, circular or cut blocks collimators for Conformal and "step and shoot IMRT" treatments, and it also performs "dynamic arcs" and "dynamic IMRT" treatments.

Device Description
DART-12 is a LINAC based Micro-Multi-Leaf-Collimator (MMLC), used in radiation treatment.
It enables shaping the Linac beam according to target geometrical and clinical requirements.
The device is composed of the MMLC module, the Linac interface module, the Workstation (with DART-12 Control Software), and the Distribution module.
The device operates in conjunction with a Linac, a treatment couch, and any additional equipment required in radiation treatment.
The MMLC apertures, (defined in treatment data file), are generated by positioning the motor-driven leaves. The motors, controlled by DART-12, bring the leaves to specified positions. The DART-12 control software operates as a sequential linear process, where the apertures are performed one by one.
To form a desired aperture, DART-12 Control Software calculates leaves motion from knowledge of their current positions (measured) and desired destination (delivered by treatment plan).
DART-12 displays an image reflecting the leaves current position. Numeric indication of each leaf position is available.
DART-12 three operation modes are: Step-and-Shoot, Dynamic Arc. and dynamic IMRT.

(a)
Identification. A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.(b)
Classification. Class II. When intended for use as a quality control system, the film dosimetry system (film scanning system) included as an accessory to the device described in paragraph (a) of this section, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

- Step-and-Shoot: MMLC modifies the apertures prior to irradiation.
- Dynamic Arc: Irradiating Linac forms an arc while DART-12 forms apertures at a set of Gantry angles.
- DIMRT: Irradiating Linac is stationary while DART-12 modifies the apertures.
Substantial Equivalence:
The predicate devices for substantial equivalence are:
The Dart-12 is substantially equivalent to its predicate devices as the basic features design and intended use are the same or similar. The minor differences in design dimensions and features between the Dart-12 and its predicate devices raise no issues of safety and efficacy as these differences have no effect on the performance, function or intended use of DART-12.
