Verista Imaging ISOCAM II Gamma Camera is intended to image the distribution of radionuclides in the body by means of photon radiation detector(s).
The ISOCAM II Gamma Camera is a medical imaging device used in nuclear medicine. It produces gamma ray distribution emitting radionuclides. It consists of one or more detectors mounted on a gantry that is connected to an acquisition system for operating the camera and storing the images. The base unit is a nuclear imaging device which utilizes gamma ray scintillation technologies. The modification to the device is limited to an upgrade to the mechanical operation of the device. The modifications improve patient safety through changes to the arm drive mechanical components and the addition of a weighted counter balance system.
The provided text describes a 510(k) summary for the Verista Imaging ISOCAM II Gamma Camera. It focuses on demonstrating substantial equivalence to predicate devices, primarily due to a mechanical upgrade, rather than a clinical performance study involving acceptance criteria for diagnostic accuracy. Therefore, several requested tables and sections are "Not Applicable" or cannot be filled due to the nature of the submission.
Here's a breakdown of the requested information based on the provided text:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Not specified. This submission focuses on mechanical upgrades and substantial equivalence, not clinical performance metrics with defined acceptance criteria. | Not specified. The submission states that modifications improve patient safety through changes to mechanical components. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample size for test set: Not applicable. No clinical test set involving patient data was used for this submission. The testing conducted was non-clinical, focusing on mechanical changes.
- Data provenance: Not applicable.
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)
Not applicable. No expert review of a test set for ground truth establishment was conducted or mentioned, as the submission is for mechanical modifications, not clinical performance.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. No test set requiring adjudication was used.
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
Not applicable. This device is a gamma camera, not an AI-powered diagnostic tool, and the submission is for mechanical upgrades. No MRMC study was conducted.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This is a medical imaging device (gamma camera), not an algorithm or AI. The submission focuses on device mechanics.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not applicable. No ground truth for diagnostic accuracy was established or used, as the submission is for mechanical modifications to an existing device. The software "remains identical" to the predicate device.
8. The sample size for the training set
Not applicable. No training set was used. This submission is for mechanical modifications to an existing device, not for training a new algorithm or AI model.
9. How the ground truth for the training set was established
Not applicable. No training set was used.

6. Intended Use:
Verista Imaging ISOCAM II Gamma Camera is intended to image the distribution of radionuclides in the body by means of photon radiation detector(s).
7. Comparison to Predicate Devices:
The base device pf the modified Verista Imaging ISOCAM II Gamma Camera has the same technological characteristics as the predicate gamma cameras. The software contained in the subject device has not been modified as a result of the modifications made to the device and remains identical to the software contained in the predicate device(s). The modifications made to the subject device do not raise any new issues of safety or effectiveness.
Discussion of Non-Clinical Tests Performed for Determination of 8. Substantial Equivalence are as follows:
Verista Imaging, Inc. has conducted testing to verify and validate the changes made to the previously cleared Park Medical Systems ISOCAM Gamma Camera.
9. Discussion of Clinical Tests Performed: Not Applicable
10. Conclusions:
Verista Imaging's ISOCAM II Gamma Camera that is the subject of this submission is a modification to the previously marketed Park Medical System's ISOCAM Gamma Cameras, to re-design an arm drive mechanism. The modified subject device has the
{2}------------------------------------------------
same intended use and indications for use, similar principles of operation, and similar technological characteristics as the previously cleared predicate device(s). Thus, the modified subject device is substantially equivalent to the predicate device(s).
