The device is a Positron Emission Tomography (PET) Imaging System. It is intended to produce images depicting the anatomical distributions of single photon and positron emitting radioisotopes with the human body for interpretation by medical personnel.

Device Description

The Allegro Imaging System is a Positron Emission Tomography (PET) system, a nuclear medical imaging system with capabilities to acquire, process, and display clinical images that can be utilized in both conventional, fixed installations or mobile environments. It is intended to produce attenuation and non-attenuation corrected images depicting the anatomical distribution of single photon and positron emitting radioisotopes within the head, body, or total body for interpretation by medical personnel. The system allows the reconstruction of high-resolution, three-dimensional, static, gated, and dynamic images of biochemical and metabolic processes.

AI/ML Overview

The provided text describes information about the Allegro Imaging System. However, it does not contain specific details about acceptance criteria and a study proving the device meets those criteria in the format requested in the prompt.

The document indicates:

Device Performance: "The device performance was measured in accordance with NEMA-NU2 standard." This suggests the NEMA-NU2 standard likely serves as a reference for performance, but no specific metrics or thresholds are provided.
Comparison to Predicate Device: The conclusion states that the device is "substantially equivalent to the predicate device based upon similar intended use, technological comparison, and system performance." This implies that the performance of the new device aligns with that of the predicate device (Allegro Imaging System K003434).

Therefore, I cannot fulfill the request for a table of acceptance criteria and reported device performance, nor can I provide information about sample sizes, ground truth establishment, expert qualifications, adjudication methods, MRMC studies, or standalone performance for a specific study. The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a predicate device rather than detailing specific performance studies with acceptance criteria.

Missing Information:

A specific table of acceptance criteria and reported device performance.
The sample size used for any test set.
The data provenance (country of origin, retrospective/prospective).
The number of experts and their qualifications used to establish ground truth.
The adjudication method.
Whether a multi-reader multi-case (MRMC) comparative effectiveness study was done, or its effect size.
Whether standalone performance was evaluated.
The type of ground truth used (e.g., pathology, outcomes).
The sample size for the training set.
How the ground truth for the training set was established.

Comparison to Predicate Device I.

The Allegro Imaging System software is an evolution of the features and functionalities of the existing Allegro Imaging System (K003434, 11/16/2003). Design modifications include enhancements in DICOM functionality, patient positioning capabilities, and cardiac imaging and analysis. Similarities and differences between the device and its predicate are described within the 510(k) submission.

In conclusion, the device is substantially equivalent to the predicate device based upon similar intended use, technological comparison, and system performance.

Dear Mr. Welte:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA), You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class 111 (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
