No
The summary describes image processing ("FineView") but does not mention AI, ML, or any related concepts like deep learning, neural networks, or training/test sets for algorithmic development. The performance studies focus on image quality and dose, not algorithmic performance metrics.
No
The device is used for imaging breast tissue samples to verify that the correct tissue has been excised during a biopsy procedure; it does not directly treat a disease or condition.
No
The device is intended to provide rapid verification that the correct tissue has been excised during a biopsy procedure by imaging the excised breast tissues, not to diagnose a condition.
No
The device is described as an "additional option" that "builds upon" a previously cleared hardware device (Pristina Serena Stereotaxy biopsy device). It enables imaging and image processing, which are functions of a larger hardware system. While it involves software for image processing, it is not solely software and relies on the underlying hardware for image acquisition.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease. This examination is performed outside of the living body (in vitro).
- Device Function: The described device, Sample Imaging for Senographe Pristina, is an imaging device that takes digital X-ray images of excised breast tissue samples. Its purpose is to visually verify that the correct tissue has been excised during a biopsy procedure.
- Method of Analysis: The device uses X-ray imaging to analyze the physical structure of the tissue sample. It does not perform any biochemical, immunological, or molecular analysis of the sample itself.
- Intended Use: The intended use is to provide images for rapid verification of tissue excision, not to diagnose a disease based on the composition or characteristics of the tissue sample itself.
While the device works with a tissue sample, the analysis is based on imaging the sample's physical presence and structure, not on performing in vitro tests on the sample's biological components. It's a tool to aid in the biopsy procedure by providing visual confirmation, not a diagnostic test performed on the sample in a lab setting.

Device Trade Name: | Sample Imaging for Senographe Pristina |
Common/Usual Name: | Sample Imaging option for the Biopsy applications (Pristina Serena and |
Pristina Serena 3D) for the Senographe Pristina mammography platform. | |
Classification Names: | 21 CFR 892.1715, Class II |
Product Code: | MUE |
Predicate Device: | MAMMOMAT Revelation with InSpect feature (K173408) |
Reference devices: | Pristina Serena (K173576) |
Device Description: | Sample Imaging for Senographe Pristina is an additional option that |
builds upon the Pristina Serena Stereotaxy biopsy device cleared on May | |
14, 2018 (K173576). | |
The Sample Imaging option enables the imaging of breast tissue samples | |
collected during biopsy medical application. In other words, the Sample | |
Imaging option provides the capability to image, within the same | |
examination, and while the patient is still under compression, the breast | |
tissue samples collected during biopsy procedures performed with any | |
biopsy medical application available on the system. The acquisition of | |
such images is done with dose to the patient limited to scatter radiation | |
from the samples. | |
Intended Use: | The Sample Imaging option is intended to provide digital X-ray images |
of biopsy excised breast tissues. | |
Indications for Use | The Sample Imaging option for Senographe Pristina™ with Pristina |
Serena™ biopsy option is intended to provide digital X-ray images of the | |
biopsy excised breast tissues while the patient is still under compression, | |
to allow rapid verification that the correct tissue has been excised during | |
the biopsy procedure. | |
Technology: | The Sample Imaging option uses an angulated 2D view acquired either at |
+15° or -15° gantry angulation to image breast tissue samples collected | |
during biopsy procedures performed during biopsy procedures with any | |
biopsy medical application available on the system. The angulated image | |
is acquired without moving the patient from the position in which the | |
sample collection was performed, nor modifying the compression applied | |
to the breast. Therefore, sample imaging does not affect the biopsy setup. | |
The Sample Imaging option can be used to image breast tissues extracted | |
during micro or macro biopsy with a vacuum assisted device or core | |
biopsy device for histopathology analysis. | |
Substantial Equivalence | |
/ Predicate and | |
Reference Devices | The proposed device Sample Imaging for Senographe Pristina™ and the |
predicate device InSpect feature on the Mammomat Revelation | |
(K173408) share an equivalent intended use and indications for use and | |
are used for the purpose of providing digital X-Ray images of biopsy | |
excised breast tissues. | |
Both features provide the capability of continuous zoom which allows the | |
user to reach a zoom identical or better that what the magnification glass | |
offers. | |
The fundamental principles of operation, functionalities, specifications | |
and technological characteristics of Sample Imaging option are | |
equivalent to InSpect feature on the MAMMOMAT Revelation. | |
The proposed device Sample Imaging for Senographe Pristina™ and the | |
reference device Pristina Serena™ offer the same image chain but | |
different image processing are applied. | |
The Sample Imaging function was designed to provide an image quality | |
performance equivalent or better than Pristina SerenaTM as demonstrated | |
in Image Quality Performance Bench Testing results. | |
The image quality and dose characteristics and performances of the | |
Sample Imaging are equivalent to those of the reference device Pristina | |
SerenaTM. | |
Determination of | |
Substantial Equivalence: | The device has successfully completed required design control testing per |
GE Healthcare's quality management system. No unexpected test results | |
were obtained. The Sample Imaging for Senographe Pristina option was | |
designed and will be manufactured under the Quality System Regulations | |
of 21CFR 820 and ISO 13485. The following quality assurance measures | |
were applied to the development of the system: | |
Risk Analysis Design Reviews Software Development Lifecycle Testing on unit level (Module verification) Integration testing (System verification) Performance testing (Verification) Safety testing (Verification) Simulated use testing (Validation) The safety and performance of the Sample Imaging option was | |
demonstrated through full verification testing and additional engineering | |
bench performance testing such as: | |
Non-Clinical Data: | |
Image Quality test that demonstrates that images | |
acquired with Sample Imaging are of same quality as | |
images acquired with Pristina Serena or Pristina | |
Serena 3D. The image quality assessment conducted | |
shows that Sample Imaging views have better | |
performance than 2D scout biopsy and DBT biopsy | |
views. The image quality assessment was performed | |
with the ACR mini stereotactic breast biopsy | |
accreditation phantom. The test results demonstrate | |
that image quality of Sample Imaging mode is | |
sufficient to verify the presence of targeted tissues in | |
the samples and to achieve its indications for use. |

MTF was measured using the same acquisition O techniques and compared between biopsy area and sample imaging area. Images were processed with "FineView" adapted to biopsy and simple imaging parameters respectively. With "FineView" applied, the MTF of the Sample images is higher than the MTF for the Biopsy 2D images at any frequency. Patient Radiation Dose Testing: Since the breast of the O patient is not in the primary X-ray beam, no direct radiation dose is delivered to the patient. However, since the primary X-Ray beam can be in close proximity to the breast, scatter radiation from the samples and detector were measured. The Air Kerma at the point of skin entry in the patient's breast closest to the biopsy samples being imaged was measured at 1.99% of the Entrance Skin Air Kerma (ESAK) from a biopsy AOP scout view for an average breast. Sample Imaging Design and Usability Validation Report contains evidence of validation of claims and performance bench testing. These tests were performed to provide the requisite data to substantiate performance, claims, and ultimately substantial equivalence. The testing demonstrated that Sample Imaging for Senographe Pristina performs according to specifications and functions as intended. Conclusion: Based on: conformance to standards; development under GE Healthcare's quality management system and design controls; successful verification/validation testing; utilization of the very well established stereotactic imaging principles and additional bench performance testing, GE Healthcare believes that the optional Sample Imaging for Senographe Pristina is substantially equivalent to its predicate device MAMMOMAT Revelation with InSpect feature (K173408) and reference device Pristina Serena (K173576). Therefore, GE Healthcare concludes that Sample Imaging for Senographe Pristina is as safe and as effective as the Predicate device for its intended use.

predicate device InSpect feature on the Mammomat Revelation | |
(K173408) share an equivalent intended use and indications for use and | |
are used for the purpose of providing digital X-Ray images of biopsy | |
excised breast tissues. | |
Both features provide the capability of continuous zoom which allows the | |
user to reach a zoom identical or better that what the magnification glass | |
offers. | |
The fundamental principles of operation, functionalities, specifications | |

equivalent to InSpect feature on the MAMMOMAT Revelation. | |
The proposed device Sample Imaging for Senographe Pristina™ and the | |
reference device Pristina Serena™ offer the same image chain but | |
different image processing are applied. | |
The Sample Imaging function was designed to provide an image quality | |
performance equivalent or better than Pristina SerenaTM as demonstrated | |
in Image Quality Performance Bench Testing results. | |
The image quality and dose characteristics and performances of the | |
Sample Imaging are equivalent to those of the reference device Pristina | |

MTF was measured using the same acquisition O techniques and compared between biopsy area and sample imaging area. Images were processed with "FineView" adapted to biopsy and simple imaging parameters respectively. With "FineView" applied, the MTF of the Sample images is higher than the MTF for the Biopsy 2D images at any frequency. Patient Radiation Dose Testing: Since the breast of the O patient is not in the primary X-ray beam, no direct radiation dose is delivered to the patient. However, since the primary X-Ray beam can be in close proximity to the breast, scatter radiation from the samples and detector were measured. The Air Kerma at the point of skin entry in the patient's breast closest to the biopsy samples being imaged was measured at 1.99% of the Entrance Skin Air Kerma (ESAK) from a biopsy AOP scout view for an average breast. Sample Imaging Design and Usability Validation Report contains evidence of validation of claims and performance bench testing. These tests were performed to provide the requisite data to substantiate performance, claims, and ultimately substantial equivalence. The testing demonstrated that Sample Imaging for Senographe Pristina performs according to specifications and functions as intended. Conclusion: Based on: conformance to standards; development under GE Healthcare's quality management system and design controls; successful verification/validation testing; utilization of the very well established stereotactic imaging principles and additional bench performance testing, GE Healthcare believes that the optional Sample Imaging for Senographe Pristina is substantially equivalent to its predicate device MAMMOMAT Revelation with InSpect feature (K173408) and reference device Pristina Serena (K173576). Therefore, GE Healthcare concludes that Sample Imaging for Senographe Pristina is as safe and as effective as the Predicate device for its intended use.
