The document describes image processing software (MUSICA) but does not mention AI, ML, or related terms. The focus is on image processing algorithms and dose reduction claims.
No.
The device is indicated for capturing diagnostic quality radiographic images, not for providing therapy.
Yes
Explanation: The device is indicated for use to "capture for display diagnostic quality radiographic images of human anatomy." This explicitly states its role in producing images used for diagnosis, which classifies it as a diagnostic device.
No
The device description explicitly states it is a "solid state x-ray system, a direct radiography (DR) system" and a "combination of Agfa HealthCare's NX Workstation, one or more flat-panel detectors, needlephosphor detectors". This indicates it includes significant hardware components beyond just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The description clearly states that the Agfa HealthCare's DX-D Imaging Package is an x-ray system used to capture radiographic images of human anatomy. It works by using x-rays to create images of internal structures, not by analyzing biological specimens.
The device is a medical imaging system, specifically a Direct Radiography (DR) system, used for diagnostic imaging in vivo (within the living body), not in vitro (in glass or outside the body).

Device Description
Agfa HealthCare's DX-D Imaging Package is a solid state x-ray system, a direct radiography (DR) system (product code MQB) intended to capture images of the human body. It is a combination of Agfa HealthCare's NX Workstation, one or more flat-panel detectors, needlephosphor detectors for direct radiography (DR) applications.
DX-D Imaging Package uses the NX Workstation to process data utilizing Agfa HealthCare's MUSICA image processing software, which includes optional image processing algorithms for adult, pediatric and neonatal images that were previously cleared for use in Agfa HealthCare's DX-D Imaging Package (K122736). The acronym MUSICA stands for Multi-Scale-Image-Contrast-Amplification. MUSICA acts on the acquired images to preferentially enhance the diagnostically relevant, moderate and subtle contrasts.
This submission is to obtain clearance for Agfa HealthCare to market the DX-D Imaging Package using a minimum of 50% dose reduction marketing claims.
Principles of operation and technological characteristics of the DX-D Imaging Package and predicate devices are the same. The DX-D Imaging Package is physically and electronically identical to the predicate K122736 since it is the same device; however, Agfa HealthCare would like to include a minimum of 50% dose reduction claims for marketing purposes. It uses the same workstation and same scintillator-photodetector flat panel detectors, needle-phosphor detectors and cassettes, or photo-stimulable imaging plates to capture and digitize the image.

Description of the test set, sample size, data source, and annotation protocol
An image quality evaluation was conducted with five board certified radiologists. The goal was to demonstrate that a minimum of 50% dose reduction can be achieved when using the DR DX-D30C flat panel detector or the CR HD5.0 image plate instead of the CR MD4.0 imaging plate. The study compared the computed radiography (CR) MD4.0 imaging plates to a DX-D30C digital radiography (DR) flat panel detector and to computed radiography (CR) HD5.0 imaging plates. The study confirmed that the dosage using the DR system DX-D30C and CR system HD5.0 was at least 50% lower than the CR system MD4.0.
The evaluation used five different anatomical phantoms; skull, chest, hand, abdomen and neonatal. Each phantom type was exposed using each detector type. For each condition (phantom and detector type) all the exposure parameters (kVp, grid, distance, etc) remained the same except the time (ms) which was varied. For each condition 13 exposures were made with a difference between exposures of 0.10 log E, the total range of exposures from highest to lowest was a factor of 16 times or 1.2 log E. All the acquired images were processed with the appropriate Musica 3 settings. This resulted in 13 exposures for each condition with 39 exposures on each phantom for a total of 195 images.
The images were displayed on a high quality diagnostic monitor. The left image was always the reference image; the right image was the image under evaluation. The left (reference) image was always exposed with a specific detector (CR MD 4.0) at a fixed exposure condition; the right images were a series of 13 images from a different detector type (CR HD5.0 or DR DX-D30C) to be compared to the reference image. The right (test) images were varied from high to low exposure while the left image remained the same.
For each condition the radiologists were asked to match the test images to the reference image. This was be done by scrolling through the test images until the right (test) image matched the reference image as closely as possible and the results recorded. All the images were coded and the Radiologists were not aware of the exposure conditions or detector types used.
To confirm the Radiologists' reading consistency, the image positions (left or right monitor) were reversed and a second reading session was done using a reference image from a different detector (CR HD5.0 or DR DX-D30C) and different test images (CR MD 4.0).
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Study Type: Laboratory testing and image evaluations (Image Quality Technical Evaluation and Image Quality Evaluation with radiologists).
Sample Size: Not explicitly stated for DQE. For radiologists' evaluation: 5 board-certified radiologists, 195 images (13 exposures per phantom type x 3 detector types x 5 phantom types).
AUC: Not Found
MRMC: Not Found
Standalone performance: Not Found
Key Results:
DQE Image Quality Technical Evaluation: Values are provided for Detective Quantum Efficiency (DQE) for the direct radiography Cesium Iodide (CsI) flat panel detector (DX-D35C), the computed radiography Cesium Bromide (CsBr) HD5.0 imaging plate, and the computed radiography Barium Fluoro-bromide (BaFBr) MD4.0 imaging plate. Both CsBr CR and CsI DR had better image quality than the predicate device (CR MD4.0); the DQE is more than double that of the predicate device (CR MD4.0).
Radiologists' Image Quality Evaluation: The average dose reduction for the first set was 58.7%, the average dose reduction for second set was 59.5%. The test results showed that a 58% dose reduction was possible with the DX-D30C DR detector and a 60% dose reduction with the HD5.0 CR plates when both were compared to images produced with MD4.0 CR plates which use BaFBr phosphors. These results confirm the possibility of at least a 50% dose reduction when comparing CsBr CR (HD5.0) plates or CsI DR (DX-D30C/DX-D35C) detectors to standard CR plates (MD4.0) using BaFBr or other detectors types with similar DQE to standard CR plates.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Detective Quantum Efficiency (DQE):
"Both systems have better image quality than the predicate device (CR MD4.0); the DQE is more than double that of the predicate device (CR MD4.0)."
Dose Reduction (based on radiologists' evaluation):
"The average dose reduction for the first set was 58.7%, the average dose reduction for second set was 59.5%."
"The test results showed that a 58% dose reduction was possible with the DX-D30C DR detector and a 60% dose reduction with the HD5.0 CR plates when both were compared to images produced with MD4.0 CR plates which use BaFBr phosphors."

TECHNOLOGICAL CHARACTERISTICS E.
Agfa HealthCare's DX-D Imaging Package is a solid state x-ray system, a direct radiography (DR) system (product code MQB) intended to capture images of the human body. It is a combination of Agfa HealthCare's NX Workstation, one or more flat-panel detectors, needlephosphor detectors for direct radiography (DR) applications. The NX Workstation allows users to view and processes images, and forward them to other devices (e.g. a PACS or printer).
Principles of operation and technological characteristics of the DX-D Imaging Package and predicate devices are the same. The DX-D Imaging Package is physically and electronically identical to the predicate K122736 since it is the same device; however, Agfa HealthCare would like to include a minimum of 50% dose reduction claims for marketing purposes. It uses the same workstation and same scintillator-photodetector flat panel detectors, needle-phosphor detectors and cassettes, or photo-stimulable imaging plates to capture and digitize the image.
6
The DX-D Imaging Package is integrated with compatible x-ray systems such as the DX-D 100 (K103597), DX-D 300 (K103050), DX-D 600 (K112670), DX-G (K092238), DX-M (K111324), and CR 30-X (K062223).
F. TESTING
Laboratory testing and image evaluations using equivalent test protocols as used for the cleared detectors and imaging plates were evaluated by qualified individuals employed by the sponsor to demonstrate that adequate design controls (according to 21 CFR 820.30) were in place.
. DQE Image Quality Technical Evaluation
A laboratory image quality technical evaluation was performed comparing the computed radiography and direct radiography detectors. Values are provided for Detective Quantum Efficiency (DQE) for the direct radiography Cesium Iodide (CsI) flat panel detector (DX-D35C), the computed radiography Cesium Bromide (CsBr) HD5.0 imaging plate, and the computed radiography Barium Fluoro-bromide (BaFBr) MD4.0 imaging plate.
The technical evaluation of the CsBr CR and the CsI DR illustrated a similar image quality for both systems at RQA3 and RQA5 beam qualities. Some differences can be indicated, which might be used in specific applications to optimize image quality. Both systems have better image quality than the predicate device (CR MD4.0); the DQE is more than double that of the predicate device (CR MD4.0).
The DQE is generally accepted to be the most suitable parameter for describing the imaging performance of an X-ray imaging device. It describes the ability of the imaging device to preserve the signal-to-noise ratio from the radiation scene to the resulting digital image. Since in X-ray imaging, the noise in the radiation field is intimately coupled to the air kerma level, DQE values can be considered to describe the dose efficiency of the device. The higher DQE for the CsBr CR and CsI DR as compared to the predicate device, guarantees that with both systems, the same image quality can be obtained as for the predicate device but at significant lower exposure level.
Agfa used generally accepted standards such as IEC 6220-1 when doing DOE testing. The range of exposure and doses used were designed to cover the normal ranges encountered in clinical use.
CR MD4.0 (BaFBr -PIP) vs. CR HD5.0 (CsBr-NIP) & DX-D30C (CsI-NIP) Comparison ●
An image quality evaluation was conducted with five board certified radiologists. The goal was to demonstrate that a minimum of 50% dose reduction can be achieved when using the DR DX-D30C flat panel detector or the CR HD5.0 image plate instead of the CR MD4.0 imaging plate. The study compared the computed radiography (CR) MD4.0 imaging plates to a DX-D30C digital radiography (DR) flat panel detector and to computed radiography (CR) HD5.0 imaging plates. The study confirmed that the dosage using the DR system DX-D30C and CR system HD5.0 was at least 50% lower than the CR system MD4.0.
The evaluation used five different anatomical phantoms; skull, chest, hand, abdomen and neonatal. Each phantom type was exposed using each detector type. For each condition (phantom and detector type) all the exposure parameters (kVp, grid, distance, etc) remained
7
the same except the time (ms) which was varied. For each condition 13 exposures were made with a difference between exposures of 0.10 log E, the total range of exposures from highest to lowest was a factor of 16 times or 1.2 log E. All the acquired images were processed with the appropriate Musica 3 settings. This resulted in 13 exposures for each condition with 39 exposures on each phantom for a total of 195 images.
| Detector name and (Phosphor Type) | ||||
|---|---|---|---|---|
| Phantom Type | MD 4.0 (BaFBr) | HD 5.0 (CsBr) | DX-D 30c (Csl) | Total Exposures |
| Skull | 13 | 13 | 13 | 39 |
| Chest | 13 | 13 | 13 | 39 |
| Abdomen | 13 | 13 | 13 | 39 |
| Hand | 13 | 13 | 13 | 39 |
| Neonatal | 13 | 13 | 13 | 39 |
| Total Exposures | 65 | 65 | 65 | 195 |
The images were displayed on a high quality diagnostic monitor. The left image was always the reference image; the right image was the image under evaluation. The left (reference) image was always exposed with a specific detector (CR MD 4.0) at a fixed exposure condition; the right images were a series of 13 images from a different detector type (CR HD5.0 or DR DX-D30C) to be compared to the reference image. The right (test) images were varied from high to low exposure while the left image remained the same.
For each condition the radiologists were asked to match the test images to the reference image. This was be done by scrolling through the test images until the right (test) image matched the reference image as closely as possible and the results recorded. All the images were coded and the Radiologists were not aware of the exposure conditions or detector types used.
To confirm the Radiologists' reading consistency, the image positions (left or right monitor) were reversed and a second reading session was done using a reference image from a different detector (CR HD5.0 or DR DX-D30C) and different test images (CR MD 4.0). The average dose reduction for the first set was 58.7%, the average dose reduction for second set was 59.5%. This is a minimal difference.
The primary endpoint was that the test images would demonstrate a minimum of a 50% dose reduction using the CsBR CR (HD5.0) imaging plate and the CsI DR (DX-D30C) detector compared to the BaFBr CR (MD4.0) imaging plate.
The test results showed that a 58% dose reduction was possible with the DX-D30C DR detector and a 60% dose reduction with the HD5.0 CR plates when both were compared to images produced with MD4.0 CR plates which use BaFBr phosphors.
These results are consistent with the technical evaluation of each system and confirm the possibility of at least a 50% dose reduction when comparing CsBr CR (HD5.0) plates or CsI DR (DX-D30C/DX-D35C) detectors to standard CR plates (MD4.0) using BaFBr or other detectors types with similar DQE to standard CR plates.
No animal or clinical studies were performed in the development of the DX-D Imaging Package.

G. RISK ASSESSMENT AND MANAGEMENT SUMMARY
During the final risk analysis meeting, the risk management team concluded that the medical risk is no greater than with conventional x-ray film previously released to the field.
There are no residual risks for the released NX software versions NX8800 (NX Ikonos) in the ALARP region after mitigation. Only two risks were identified in the Broadly Acceptable Region. Therefore the device is assumed to be safe, the benefits of the device are assumed to outweigh the residual risk.
The term "Level of Concern" means the level of risk that the software device is determined to be if the software were to fail. The Level of Concern for the device has been determined to be moderate.
H. CONCLUSIONS
The DX-D Imaging Package indications for use is equivalent to both predicates (K122736 and K092238). Both the DX-D Imaging Packag and predicate devices (K122736 and K092238) include the statement that the device is not indicated for mammography, and include pediatric and neonatal patient populations. The predicate device (K092238) includes system options and accessories; which are also available on the DX-D Imaging Package and predicate K122736.
