No
The description focuses on standard digital image processing tools and volumetric analysis, with no mention of AI or ML techniques.
No.
The device is an image analysis software package designed to support physicians in evaluating, documenting, and following up on lung lesions. It provides tools for volumetric analysis and classification, which are diagnostic and monitoring functions, not therapeutic.
Yes
The device is designed to support physicians in confirming the presence or absence of lung lesions and evaluating, documenting, and following up on such lesions using volumetric analysis, which directly aids in diagnosis and disease management.
Yes
The device is explicitly described as a "self-contained image analysis software package" and its description focuses solely on software functionalities and algorithms for processing CT data. There is no mention of accompanying hardware components or hardware-specific validation.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that Lung CARE CT is an image analysis software package that evaluates CT volume data sets. This data comes from medical imaging, not from biological samples.
- Intended Use: The intended use is to support physicians in evaluating and following up on lung lesions identified in CT scans. This is a diagnostic aid based on imaging, not a test performed on a biological sample.
The device processes medical images to provide information to a physician, which falls under the category of medical imaging software or a diagnostic imaging device accessory, not an in vitro diagnostic device.

Intended Use / Indications for Use
Lung CARE CT is a self-contained image analysis software package for evaluating CT volume data sets. Combining enhanced commercially available digital image processing tools with optimized workflow and reporting tools, the software is designed to support the physician in confirming the presence of absence of physician-identified lung lesions (eg. nodules) in addition to evaluation, documentation and follow-up of any such lesions using standard or low-dose spiral CT scanning. This evaluation tool allows for volumetric analysis of pulmonary nodule or lesion size over time, helping the Physician to assess the changes in their growth. It is also designed to help the physician classify conspicuous regions of tissue unambiguously, with respect to their size, dimensions, shape and position.

Device Description
This premarket notification covers Siemens LungCARE CT software package. It is based on Siemens syngo software platform.
Lung CARE CT is a self-contained image analysis software package for cvaluating CT volume data sets. Combining enhanced commercially available digital image processing tools (MIP, MPR, SSD, VRT), evaluation tools (volumetric estimation using consistent standardized measurement protocol, comparator tool for nodule matching by synchronization of two datasets, classification of nodules using configurable descriptors) and reporting tools (targeted presets, saved lesion) with optimized workflow palette, the software package is designed to support the physician in confirming the presence of physician identified lung lesions (eg. nodulcs) in addition to evaluation, documentation and follow-up of any such lesions using standard or low-dose spiral CT scanning. This visualization tool allows for volumetric analysis of pulmonary nodule or lesion size over time, helping the Physician to assess the changes in their growth. It is also designed to help the physician classify conspicuous regions of tissue unambiguously, with respect to their size, dimensions, shape and position.

Summary of Performance Studies
Kohl et al., performed a Lung Phantom bench testing study to determine the influence of the scanning and reconstruction parameters on reproducibility of volume measurements using LungCARE CT. The results indicate that the reproducibility of volumetric mcasurements is independent of reconstructed field of view but is slightly dependent on the reconstruction kernel used to perform the evaluation. The results also clearly demonstrate the advantage of using thin slice collimations for better reproducibility of volume measurements. Comparison of volument measurements performed at various dose levels clearly demonstrates that the usage of normal dose versus low dose brings no additional benefit to the volume estimation. In conclusion, the authors propose that the end-user should use thin slice collimations, medium kernel, low radiation dose with a full field of view reconstruction and last but not the least consistently use the same protocol for the best reproducibility of volumetric estimation.
Wormanns et al., performed a clinical evaluation of the reproducibility of volumetric measurements using LungCARE CT in 10 patients with pulmonary metastatic disease. In total 150 pulmonary nodules were manually marked and then evaluated. Volume and diameter of the nodules was calculated with the LungCARE CT software package. The proposed segmentation results, provided by the software package, were not modified by the user. The results indicate that the clearly defined compact type of pulmonary nodules have a better volume reproducibility, than the ill-defined types of nodules with multiple connections to pleura and/or vessels without user intervention by modifying the segmentation results. The authors concluded that they had evaluated a method that allows for the reliable estimation of volume growth but the user is cautioned to carry out the evaluation carefully and always critically assess the visual representation of the software proposed segmentation results especially for ill-defined nodules.

General Safety and Effectiveness Concerns:
The device labeling contains instructions for use and any necessary cautions and warning, to provide for safe and effective use of the device.
Risk management is cosured via a hazard analysis, which is used to identify potential hazards. These potential hazards arc controlled via software development, verification and validation testing. To minimize electrical, mechanical, and radiation hazards, Siemens adheres to recognized and established industry practice and standards.

Substantial Equivalence:
The LungCARE CT software package, addressed in this premarket notification, is substantially equivalent to the following commercially available software package:
| Manufacturer | Product | 510(k) | Clearance date |
|---|---|---|---|
| GE Medical | Advanced Lung Analysis-I | K013381 | 10/26/01 |
The LungCARE CT software package described in this 510(k) has the same intended use and similar technical characteristics as the commercially available software listed above.
In addition, the image processing, display and evaluation components of LungCARE are currently available software components on CT systems like Siemens Somatom Plus 4 with Volume Zoom option, K941546, cleared on September 20th, 1994, software options like the Volume Rendering Technique option, K923524/S2, cleared on May 17th 1994 and the Calcium Scoring Software package, K990426 cleared on 04/30/99, and Workstations like the Siemens RealTime 3D Diagnostic Workstation (3D Virtuoso), K973010, which received clearance on Nov 10th 1997 and the syngo Multimodality Workstation. K010938, cleared on 26th June 2001. LungCARE packages these image processing and image display components in an optimized workflow palette.
In summary, Siemens is of the opinion that LungCARE CT software package does not introduce any new potential safety risks and is substantially equivalent to and performs as well as the predicate software components and the predicate device.
