Intended Use

Advanced Lung Analysis II is intended to provide an optimized non-invasive application to measure abnormalities in the lung (for example, nodules, lesions, etc.) from a set of Computed Tomography (CT) images. The software is designed to support the physician in confirming the presence or absence of physician identified lung lesions (e.g. nodules). The software allows measurement of volume over time using a consistent standardized measurement protocol, thus providing an estimation of the volume doubling time. ALA II software allows analysis and displays statistics for nodule characterization all the different nodule types. ALA II optional Digital Contrast Agent (DCA) module is an automated highlight feature for the visual identification of possible lesions. Digital Contrast Agent (DCA) is a 3D filter that produces images that highlight spherical (S) and cylindrical (C) anatomical regions, such as nodules, cysts, scars, and vessels. Images are made available to the physician to aid in characterization of suspicious nodules and thus, the patient management care decision process. ALA II provides to physician with additional information, meant to complement diagnosis based on classical techniques.

Indications for Use

Indicated for physicians to assist in the assessment and measurement of lung abnormalities (e.g., nodules, lesions) in patients undergoing CT imaging. Supports confirmation of lesion presence, volume measurement over time, and estimation of volume doubling time. Optional DCA module highlights spherical and cylindrical anatomical regions (nodules, cysts, scars, vessels) to aid characterization.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

### Device Description:

K04269y

CT Advanced Lung Analysis (ALA 2 / ALA II) is a post processing analysis software package designed to assist radiologists and other clinicians in the evaluation and assessment of nodules and other lesions in the lung.

Advanced Lung Analysis II provides an effective solution for providing quick analysis and measurements to help differentiate the radiologist's findings during the primary read. The software assesses and measures all lung nodule types, including measuring volume and their changes over time. Following a C1 scan, the user clicks on a specific nodule and the software automatically calculates and displays a 3-dimensional volume and rendering of the nodule as well as the associated measurements. Advanced Lung Analysis II also offers functionality for quick comparisons between the current and previous patient procedures.

The Digital Contrast Agent (DCA) option will further compliment the Radiologist's diagnostic capability by highlighting spherical (S) and cylindrical (C) anatomical regions, such as nodules, cysts, scars. and vessels.

ALA II and DCA are software options that operate on the GE family of LightSpeed multi-slice CT scanners. Advantage Workstation 4.2 (or higher), and GE PACS systems.

#### Indications for Use:

Advanced Lung Analysis II is intended to provide an optimized non-invasive application to measure abnormalities in the lung (for example, nodules, lesions, etc.) from a set of Computed Tomography (CT) images.

The software is dcsigned to support the physician in confirming the presence or absence of physician identified lung lesions (e.g. nodules). The software allows measurement of volume over time using a consistent standardized measurement protocol, thus providing an estimation of the volume doubling time. ALA II software allows analysis and displays statistics for nodule characterization all the different nodule types.

ALA II optional Digital Contrast Agent (DCA) module is an automated highlight feature for the visual identification of possible lesions. Digital Contrast Agent (DCA) is a 3D filter that produces images that highlight spherical (S) and cylindrical (C) anatomical regions, such as nodules, cysts, scars, and vessels. Images are made available to the physician to aid in characterization of suspicious nodules and thus, the patient management care decision process.

ALA II provides to physician with additional information, meant to complement diagnosis based on classical techniques.
