Orthopantomograph® OP200 (film unit) and OP200 D (digital unit) devices are intended to be used for producing X-ray radiographs of dentition, TM-joints and other oral structures. The units are capable of taking panoramic, TM-joint and maxillary sinus radiographs from patients. When the units are equipped with cephalometric option Orthoceph® OC200 (film unit) or OC200 D (digital unit) units can be used for cephalometric radiography and examinations related thereto. OP200 or OC200 units can also be equipped with Ortho Trans (OT) option, which is capable of taking both cross and longitudinal slices of region of interest. Ortho Trans uses linear tomography imaging principle.

Panoramic X-ray devices Orthopantomograph® OP200, OP200 D and cephalometric options Orthoceph® OC200, OC200 D are the next generation in the Orthopantomograph® and Orthoceph® family. In the case of OP200 and OC200 devices, the image is captured to the film whilst OP200 D and OC200 D offer digital imaging. The units include patented V-shaped X-ray beam that adapts to the bone density and structure of the human anatomy. In the OP200 D and OC200 D the imaging geometry remains the same as in film-based imaging (OP200, OC200), thereby enabling comparison to earlier film-based studies. The patient positioning is easy and accurate thanks to motorized movements and three light lines for correct positioning of the patient's head. The patient's midsagittal view can be seen in a panoramic mirror and the electrically locked rigid forehead support is used to stabilize the head. Patient positioning can be performed on the left or right side. When OP200 or OC200 units are equipped with CR option they have bigger 24x30cm cassette holder in panoramic side. Normal cassette holder size is 15x30cm. With this bigger 24x30cm cassette holder CR imaging plates can be used. Optional Ortho ID film marking system can be used to store exposure parameters, patient and clinic information to films. Ortho ID is connected to OP200 or OC200 film units. Equipments are designed to be field upgradeable. This means that for example basic OP200 film unit can be field upgraded to OC200 (cephalometric imaging) or OP200 D digital or OC200 D digital. All different options like OT, CR, etc. can be field upgraded afterwards.

Performa Stereo is intended to be used for breast biopsy or lesion marking with the base mammographic system Performa with stereo adapter.

Performa Stereo is a breast biopsy and lesion marking system in connection with the Performa mammographic system (#K981641). The Performa stereo is especially developed for fine needle aspiration (FNA), core biopsy, vacuum assisted biopsy and lesion marking. The Performa Stereo system consists of a biopsy unit with a needle guide and a breast support table, an adapter unit for making ±15° angles, and a film marker unit. A mechanical docking interface is used for connecting the Performa Stereo's stereo adapter and the biopsy unit together. There are no electrical connections between the biopsy unit and Performa.

The adapter unit is identical to adapter used in the case of Alpha Stereo 4 and Delta 16. The needle guide is a Cytoguide biopsy unit which is the same than used in the case of Delta 32.

In an examination two X-ray images are taken at angles of +15° and -15° degree of the region of interest in the breast. The image capturing will be made by 18x24 cm film cassette and the needle targeting driving will be made with the motorized Cytoguide needle guide unit which are the main functions of the biopsy unit. After making two individual stereotactic X-ray exposures to one film, the corresponding two images are shown side by side on the film reader unit. The user then marks the target point with a cursor on each image. Based on the marking the xyzcoordinates of target are calculated by the film marker unit. The needle holder is then automatically positioned, taking into account the coordinate information and the needle length selected. The tip of the needle, which is then inserted into the holder with correct bushings can now be used to penetrate the lesion area.

The provided document is a 510(k) premarket notification for a medical device called "Performa Stereo." This document primarily focuses on establishing substantial equivalence to predicate devices and does not contain detailed information about a study proving specific acceptance criteria for the device itself.

Here's a breakdown of the information that can be extracted and what is missing:

1. A table of acceptance criteria and the reported device performance

Missing. The document does not provide a table of acceptance criteria or reported device performance metrics. It focuses on the function and design of the device and its equivalence to previously approved devices.

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

Missing. There is no mention of a test set, sample size, or data provenance. The submission describes the device's mechanism and its intended use, rather than presenting results from a clinical or performance study.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

Missing. Since no specific test set or study is described, there is no information about experts or ground truth establishment.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

Missing. No test set or adjudication method is described.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Missing. The Performa Stereo is a mechanical system for breast biopsy and lesion marking, not an AI-powered diagnostic tool. Therefore, an MRMC study related to AI assistance is not applicable and not mentioned.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done

Missing. As the device is a physical, mechanical system, there is no "algorithm only" performance to evaluate in this context.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

Missing. No study or ground truth is described.

8. The sample size for the training set

Missing. This device is a mechanical system, not an AI model, so there is no concept of a "training set" in the context of this submission.
