No
The description focuses on hardware modifications (dual energy x-ray, filter wheel) and image processing techniques to combine images. There is no mention of AI or ML algorithms for image analysis, interpretation, or other functions. The "Automatic Optimization of Parameters (AOP)" feature is described as selecting parameters based on breast density, which is a rule-based or algorithmic approach, not necessarily AI/ML.
No
The device is used for diagnostic imaging (mammography) to localize lesions, not for treating any condition.
Yes
The device, CESM, is an extension of diagnostic mammography and is used as an adjunct following other exams to localize a known or suspected lesion, indicating its use in diagnosing health conditions.
No
The device description clearly outlines hardware components like a digital detector, x-ray tube, generator, and filter wheel, which are integral to the device's function. While software modifications are mentioned for acquisition control and image processing, the device is fundamentally a hardware system with software components, not a software-only device.
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 such as blood, urine, or tissue that have been taken from the human body. They are used to detect diseases, conditions, or infections.
- Device Function: The description clearly states that this device is a mammography system that uses X-rays to image the breast. It is an imaging device that works externally to the body, not by analyzing samples taken from the body.
- Intended Use: The intended use is for contrast enhanced breast imaging as an adjunct to mammography and ultrasound exams to localize lesions. This is an imaging procedure, not a diagnostic test performed on a biological sample.
- Device Description: The description details the components of an X-ray imaging system (digital detector, x-ray tube, generator, filters), not equipment for analyzing biological samples.
Therefore, this device falls under the category of medical imaging devices, not in vitro diagnostics.

Intended Use / Indications for Use
Contrast Enhanced Spectral Mammography (CESM) is an extension of the existing indication for diagnostic mammography with the Senographe Essential or Senographe DS. The CESM application shall enable contrast enhanced breast imaging using a dual energy technique. This imaging technique can be used as an adjunct following mammography and ultrasound exams to localize a known or suspected lesion.

Device Description
The Senographe DS and Senographe Essential are both full field digital mammography systems consisting of a digital detector, a dual track x-ray tube (molybdenum / rhodium) and an x-ray generator with control. The digital detector is a flat panel of amorphous silicon on which cesium iodide is deposited to maximize the detection of x-rays. The x-ray filter is a wheel with both a molybdenum and a rhodium filter to allow various combinations of x-ray tube track and filter when imaging breasts of different radiological densities. The system includes a feature called Automatic Optimization of Parameters (AOP) that automatically selects the kVp, the optimal x-ray tube track and beam filtration and then terminates the exposure based on the breast density to provide consistent image quality for the user across a wide range of breast sizes and densities.
The subject of this submission is a modification that will introduce a new imaging option based on a method of image acquisition involving a x-ray exposures at two energy levels. The two exposures will be completed at the simultaneously using a technique known as "dualenergy". This x-ray acquisition methodology has been previously cleared by GE Healthcare in K013481, although that clearance excludes mammography. This Premarket Notification will implement this technology on GE Healthcare's existing Full Field Digital Mammography systems as an upgrade to existing systems, or as an option to new installations. The dualenergy exposures will be done with a single breast compression and will be following an iodine based contrast injection of an existing approved x-ray contrast agent, using the approved rate, route of administration, and dosage of the contrast agent. The new mode of operation is referred to as Contrast Enhanced Spectral Mammography (CESM) due to the nature of taking an exposure with the x-ray spectrum optimized for general mammographic imaging and a second exposure with the x-ray spectrum optimized for the iodine based contrast image. The modification also includes the implementation of an additional x-ray beam filter. The change in x-ray exposure energy, plus the change in beam filtration allow the system to optimize the x-ray spectrum for the iodine based contrast when acquiring the second exposure of the dual-energy acquisition. This filtration change is done by rotating the filter wheel and changing the beam filter selected for the high energy exposure.
These two images are combined to allow visualization of the breast tissue in a way that is typical and familiar for mammographic imaging, while being able to visualize the x-ray contrast enhancement in the breast at the same time.
The Contrast Enhanced Spectral Mammography Option when utilized with the Senographe DS or Senographe Essential introduces 3 main differences:
- Modifications to the control of the x-ray acquisition sequence to allow dual energy exposures.
- Modifications to the x-ray beam filter wheel to add a new filter that changes the beam characteristics during the high energy exposure.
- Modifications to the software that is used for acquisition control and for image processing to reconstruct the image for review.

Intended Use: Indications for Use:
Contrast Enhanced Spectral Mammography (CESM) is an extension of the existing indication for diagnostic mammography with the Senographe Essential or Senographe DS. The CESM application shall enable contrast enhanced breast imaging using a dual energy technique. This imaging technique can be used as an adjunct following mammography and ultrasound exams to localize a known or suspected lesion.
Technology: The Contrast Enhanced Spectral Mammography (CESM) imaging option is a technique based on image acquisition from x-ray exposures at two different energy levels. This option utilizes a technique known as "dual-energy" which entails obtaining one exposure immediately after another. The dual energy exposures will be performed with a single breast compression and will be following an iodine based contrast injection of an existing approved x-rav contrast agent, using the approved rate, route of administration, and dosage of the contrast agent. This new mode of operation is referred to as CESM due to the concept of taking an exposure with the x-ray spectrum optimized for general mammographic imaging and a second exposure with the x-ray spectrum optimized for the iodine based contrast image.
The Contrast Enhanced Spectral Mammography Option when utilized with the Senographe DS or Senographe Essential introduces 3 main differences:
- Modifications to the control of the x-ray acquisition sequence to allow dual energy exposures.
- -Modifications to the x-ray beam filter wheel to add a new filter that changes the beam characteristics during the high energy exposure.
