Aktina Thermoplastic Masks are medical devices used for patient positioning and immobilization during external beam radiation therapy procedures. Thermoplastic masks are intended for the duration of the treatment.
This is a Traditional 510(k) for the Aktina Medical Thermoplastic Mask. The low-temperature thermoplastic mask is made of Aquaplast polycaprolactone sheets. When immersed in water heated to 70-75°C [160 to 170°F], the material softens, allowing the user to shape or stretch the mask over the contours of the patient's anatomy while cooling. When the material reaches room temperature, the mask hardens into the anatomical shape. The mask can then be placed over the patient treatment area to consistently immobilize the area from treatment to treatment. Predicate device manufacturers have used polycaprolactone materials for this intended use for over 25 years. The mask also has a polycarbonate frame with holes for mounting to the user's existing patient support hardware.
The provided document is a 510(k) summary for the Aktina Medical Thermoplastic Mask, not a study describing the acceptance criteria and performance of an AI/ML-based device. This document is for a medical device (thermoplastic mask) used for patient immobilization during radiation therapy and does not involve AI/ML.
Therefore, I cannot extract the requested information (acceptance criteria, study details, sample sizes, expert qualifications, adjudication, MRMC, standalone performance, ground truth, training set information) as it is not present in the provided text.
The document primarily focuses on demonstrating substantial equivalence to a predicate device based on material properties, design, and intended use, rather than performance evaluation against specific acceptance criteria for an AI/ML algorithm.
§ 892.5050 Medical charged-particle radiation therapy system.
(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.
