The Siemens SOMATOM Perspective system is intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from either the same axial plane taken at different angles or spiral planes* taken at different angles.
In addition the SOMATOM Perspective is able to produce additional image planes and analysis results by executing optional post-processing features, which operate on DICOM images.
For cardiac imaging, which is an option on the system, a new reconstruction algorithm (iTRIM - Iterative Temporal Resolution Improvement Method) is used. iTRIM improves the temporal resolution of cardiac CT images compared to conventional cardiac CT image reconstruction. Actual results obtained with iTRIM can vary depending on the particular clinical situation.
The images and results delivered by the SOMATOM Perspective can be used by a trained physician as an aid in diagnosis.
(*spiral planes: the axial planes resulting from the continuous rotation of detectors and x-ray tube, and the simultaneous translation of the patient.)
Similar to the predicate device (Siemens SOMATOM Emotion 16 premarket notification K050297, clearance date 03/01/2005), Siemens SOMATOM Perspective is a Computed Tomography X- ray System, which features a continuously rotating tube-detector system and functions according to the fan beam principle. The system software is a command-based program used for patient management, data management, X-ray scan control, image reconstruction, and image archive/evaluation.
The SOMATOM Perspective system produces CT images in DICOM format, which can be used by post processing applications commercially distributed by Siemens and other vendors.
SOMATOM Perspective operates with software version SOMARIS/5 which is a Windows XP®1 based program used for patient management, data management. X-ray scan control, image reconstruction, and image archive/evaluation.
The key software new features for SOMATOM Perspective are iTRIM (Iterative Temporal Resolution Improvement Method) to improve the temporal resolution to a value of about 80% of that of conventionally reconstructed images, and ECO Mode (eMode) to increase the tube life by reducing the tube power.
The computer system delivered with the CT scanner is able to run such post processing applications optionally.
The provided document is a 510(k) summary for the Siemens SOMATOM Perspective CT system. It does not contain acceptance criteria for device performance or the details of a study demonstrating that the device meets such criteria in terms of clinical output or diagnostic accuracy.
The summary focuses on demonstrating substantial equivalence to a predicate device (Siemens SOMATOM Emotion 16) based on technical characteristics and intended use. The "Nonclinical Testing" section mentions verification and validation testing, as well as phantom testing, but it does not provide specific acceptance criteria or detailed results from these tests in relation to clinical performance or diagnostic outcomes.
Therefore, for almost all of the requested information, the answer will be "Not provided in the document."
Here's a breakdown based on the information provided:
Acceptance Criteria and Device Performance Study for SOMATOM Perspective
The 510(k) summary provided does not detail specific acceptance criteria related to clinical performance (e.g., diagnostic accuracy, sensitivity, specificity) for the SOMATOM Perspective, nor does it present a study demonstrating the device meets such criteria for clinical or diagnostic endpoints.
The document primarily focuses on demonstrating substantial equivalence to a predicate device based on technical specifications and functionality, particularly for the new features like iTRIM and eMode. It mentions that "The testing results supports that all the software specifications have met the acceptance criteria," but these "software specifications" are not defined in terms of clinical outcomes or performance metrics in a way that would answer the specific questions below.
The "Nonclinical Testing" section refers to phantom testing and verification/validation, which are typical for medical device submissions, but no specific performance statistics are presented.
Therefore, the following information is largely not available from this document:
-
Table of Acceptance Criteria and Reported Device Performance: This information is not provided. The document states that "all the software specifications have met the acceptance criteria" but does not define these criteria or report specific performance metrics (like diagnostic accuracy, sensitivity, etc.) relevant to a clinical study.
-
Sample Size Used for the Test Set and Data Provenance: Not provided. The document mentions "nonclinical tests" including "phantom testing" but does not describe a test set based on patient data, its size, or provenance.
-
Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of those Experts: Not provided. Since a clinical test set with ground truth is not described, this information is not applicable here.
-
Adjudication Method for the Test Set: Not provided. As no clinical test set for diagnostic performance is described, no adjudication method is mentioned.
-
Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study: No MRMC comparative effectiveness study is mentioned in the provided text. The document refers to the iTRIM algorithm improving temporal resolution, stating that "Actual results obtained with iTRIM can vary depending on the particular clinical situation," but it doesn't quantify this improvement in terms of human reader performance or diagnostic effectiveness compared to a standard method.
-
Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study: No standalone diagnostic performance study (e.g., sensitivity, specificity, AUC) for the algorithm itself is presented. The document states that the images and results "can be used by a trained physician as an aid in diagnosis," implying human-in-the-loop operation, but no performance metrics for such use are provided.
-
Type of Ground Truth Used: Not provided. Since no clinical performance study is detailed, the type of ground truth is not mentioned.
-
Sample Size for the Training Set: Not provided. The document does not describe the development or training of an AI model with a training set.
-
How the Ground Truth for the Training Set was Established: Not provided. As no training set is described, this information is not applicable.

Dear Ms. Magnum:
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 class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
