Re: K040378 Trade/Device Name: KODAK DirectView CR Cassette/GP/15x30 cm Regulation Number: 21 CFR 892.1850
The KODAK DirectView CR cassette holds a storage phosphor screen which is exposed by radiographic equipment for the recording of a patient radiation pattern. The cassette is loaded into a compact laser scanner capable of reading the latent image. The Kodak DirectView CR 15 x 30 cm cassette and storage phosphor screen can be used for general radiology and dental panoramic radiography applications.
The Kodak DirectView CR 15 x 30 cm cassette size is designed to perform general radiography and panoramic dental exams when used with the Kodak DirectView CR 850 and CR 950 systems. The cassette system (cassette and storage phosphor screen adhered to the cassette plate) can be used in common dental panoramic x-ray dental units designed to accept cassettes that meet the ISO 4090 standard. The CR cassette is a standard x-ray diagnostic cassette used for computed radiography. The panel materials are consistent with the current design of the CR cassette and include Corus Hylite and Toray Panel. The Corus Hylite panel includes two lavers of aluminum, with polypropylene (plastic) in the middle, and is covered with Omnova (clear viny) with printing on the second surface). On the tube side of the cassette there is Toray Carbon Fiber Panel that consists of four layers of carbon fiber. The storage phosphor plate is attached to the honeycomb panel. The lead mylar that is in place under the phosphor layer of the screen was removed in the CR 15 x 30 cm cassette in order to accommodate Automatic Exposure Control (AEC) in dental x-ray units.
This 510(k) submission (K040373) for the KODAK DirectView CR Cassette / GP / 15 x 30 cm does not describe a study with acceptance criteria and device performance in the typical sense of a diagnostic algorithm or predictive model. Instead, it focuses on demonstrating substantial equivalence of a physical medical device (an X-ray cassette) to a previously cleared predicate device. Therefore, the information provided in the input does not directly align with the requested structure for acceptance criteria and study details for an AI/algorithm-based device.
However, I can extract and present the relevant information provided in the context of substantial equivalence for a physical medical device. The "acceptance criteria" here are implicitly tied to the performance requirements for an X-ray cassette, and the "study" is the comparison made to the predicate device.
Here's an interpretation based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria Category | Implicit Acceptance Criteria (based on predicate) | Reported Device Performance (compared to predicate) |
|---|---|---|
| Functionality | Must hold a storage phosphor screen, be exposed by radiographic equipment, and be loaded into a laser scanner to read the latent image. | "identical in function" to the currently marketed Kodak DirectView CR cassette. |
| Radiographic Applications | Suitable for general radiology and dental panoramic radiography applications. | Can be used for general radiology and dental panoramic radiography applications. |
| Compatibility with Dental Units | Must be compatible with common dental panoramic x-ray units designed to accept cassettes that meet the ISO 4090 standard. | Can be used in common dental panoramic x-ray dental units designed to accept cassettes that meet the ISO 4090 standard. |
| Panel Materials | Materials should be consistent with current CR cassette designs, ensuring structural integrity and proper X-ray interaction. | Panel materials (Corus Hylite, Toray Panel, Omnova) "consistent with the current design." |
| AEC Compatibility | Must accommodate Automatic Exposure Control (AEC) in dental X-ray units (a design change from previous versions). | Lead mylar removed to "accommodate Automatic Exposure Control (AEC) in dental x-ray units." |
| Image Processing Software | Must function with existing image processing software without requiring modification. | "image processing software algorithm will not be modified" and remains the same as previously cleared. |
| Overall Performance | Performance should be equivalent to the predicate device for its intended use. | "identical in...performance" to the currently marketed Kodak DirectView CR cassette. |
2. Sample Size Used for the Test Set and Data Provenance
This is not applicable in the context of this 510(k) submission. The "test set" here would refer to the physical cassette itself being compared. The comparison is primarily based on design specifications, materials, and functional claims relative to a predicate device, rather than a clinical trial with a "test set" of patient data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. Ground truth for a physical X-ray cassette's performance is established by engineering specifications, material properties, and regulatory standards, not by expert interpretation of clinical images from a "test set." The FDA reviewers evaluate the technical documentation.
4. Adjudication Method for the Test Set
Not applicable. There isn't a "test set" of cases requiring adjudication in this type of submission.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This device is a passive X-ray cassette, not an AI or imaging interpretation algorithm. Therefore, an MRMC study related to human reading performance with or without AI assistance is irrelevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. The device is a physical X-ray cassette, not an algorithm.
7. The Type of Ground Truth Used
The "ground truth" implicitly used for demonstrating substantial equivalence are:
- Engineering Specifications: Design, materials, and manufacturing standards for X-ray cassettes.
- Regulatory Standards: Adherence to standards like ISO 4090 for dental panoramic cassettes.
- Predicate Device Performance: The established, cleared performance of the Kodak Ektascan SP Cassette (K925997) / Kodak DirectView CR Cassette serves as the benchmark for "truth."
8. The Sample Size for the Training Set
Not applicable. This is a physical device, not a machine learning algorithm, so there is no training set.
9. How the Ground Truth for the Training Set was Established
Not applicable. There is no training set for this device.
Summary of the Study that Proves the Device Meets Acceptance Criteria:
The "study" proving the device meets its (implicit) acceptance criteria is the Substantial Equivalence demonstration. The manufacturer asserts and provides documentation to support that the KODAK DirectView CR 15 x 30 cm cassette is substantially equivalent to the Kodak Ektascan SP Cassette (K925997) (currently marketed as the Kodak DirectView CR Cassette).
The key arguments for this demonstration are:
- Identical Function and Performance: The new cassette size is stated to be "identical in function and performance" to the predicate.
- Consistent Panel Materials: The panel materials are consistent with the current design, using Corus Hylite and Toray Panel.
- AEC Accommodation: A specific design modification (removal of lead mylar) was made to accommodate Automatic Exposure Control (AEC) in dental X-ray units, which is a functional enhancement for specific applications.
- Unchanged Image Processing Software: The device uses the same, previously cleared, image processing software algorithm, ensuring consistent image quality and processing characteristics.
- Broad Application: It maintains suitability for general radiology and dental panoramic radiography and is compatible with ISO 4090 standard dental X-ray units.
The FDA reviewed these claims and determined that the device is substantially equivalent, allowing it to be marketed. This regulatory approval serves as the "proof" that the device meets its acceptance criteria for safety and effectiveness, based on its equivalence to a device already on the market.

| Classification Name: | Radiographic film cassette (per 21 CFR 892.1850
Trade/Device Name: LifeRay™ FW Mammo Cassette LifeRay™ KW Mammo Cassette Regulation Number: 21 CFR 892.1850
Ferrania LifeRay™ Mammo Cassettes are intended for use during mammography diagnostic procedures to hold radiographic film in close contact with an x-ray intensifying screen and to provide a light proof enclosure for direct exposure of this film.
Ferrania LifeRay™ Mammo Cassettes are intended for use during mammography diagnostic procedures to hold radiographic film in close contact with an x-ray intensifying screen and to provide a light proof enclosure for direct exposure of this film. The Cassettes are available in two sizes and two models. The LifeRay™ KW Mammo Cassettes contain a window that is compatible with Kodak ID Printers for marking film with patient identification data. The LifeRay™ FW Mammo Cassettes contain a window that is compatible with Ferrania ID Printers for the same purpose as before.
Both Ferrania LifeRay™ Mammo Cassettes and the predicate device are composed of:
- a light tight chamber for preventing radiographic film exposure,
- a compressible backplate material to assure intimate film-screen contact,
- a latching mechanism for removal and replacement of radiographic film.
The provided text describes a 510(k) premarket notification for Ferrania S.p.A. LifeRay™ Mammo Cassettes. However, it does not contain information about acceptance criteria, device performance metrics, or a formal study proving the device meets specific criteria.
The submission states that the device is "substantially equivalent" to a predicate device (Kodak MIN-R 2 CASSETTE) based on technological characteristics and adherence to voluntary standards. This type of submission relies on demonstrating that the new device is as safe and effective as a legally marketed device, rather than proving performance against specific quantitative acceptance criteria through a dedicated performance study with human readers or standalone algorithm performance.
Here's an analysis of the requested information based on the provided text, highlighting what is present and what is absent:
Description of Acceptance Criteria and Study to Prove Device Meets Criteria
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Not Explicitly Stated | The device "performs as well as the predicate device" (Kodak MIN-R 2 CASSETTE). This is a qualitative comparison rather than specific quantitative performance metrics. |
| Conformity to ANSI PH1.49 1995² (Radiographic Film Cassettes) | Yes, the device conforms to this standard. |
| Conformity to ISO/FDIS 4090: 2000 (Non-screen-type Medical Radiographic Films) | Yes, the device conforms to this standard. |
Explanation: The document does not define specific quantitative acceptance criteria such as sensitivity, specificity, or image quality metrics. Instead, the "acceptance" is based on substantial equivalence to a predicate device and conformity to relevant industry standards. The reported performance is a qualitative statement of equivalence.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not applicable. No test set of radiographic images or patient data is mentioned. The assessment relies on a comparison of device characteristics and adherence to standards, not a clinical performance study.
- Data Provenance: Not applicable. No clinical data or test data is mentioned.
Explanation: This 510(k) summary is for a radiographic film cassette, not an imaging algorithm or a device that produces diagnosable images itself. Therefore, a "test set" of images or patient data with an established ground truth is not relevant to this submission. The device's performance is intrinsically linked to its physical characteristics and ability to hold film and screens properly, as assessed against standards and a predicate device.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- Number of Experts: Not applicable. No "ground truth" was established for a test set as there was no study comparing diagnostic outcomes.
- Qualifications of Experts: Not applicable.
Explanation: As no clinical performance study involving diagnostic interpretation was conducted for the cassette itself, there were no experts used to establish a ground truth.
4. Adjudication Method for the Test Set
- Adjudication Method: Not applicable. No test set requiring expert adjudication was used.
Explanation: Without a clinical or image-based test set, adjudication methods are irrelevant here.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- MRMC Study: No, an MRMC comparative effectiveness study was not done.
- Effect Size: Not applicable.
Explanation: An MRMC study is typically performed for AI or imaging devices where human interpretation is involved. This device is a passive film cassette, and its effectiveness is not measured by its ability to assist human readers in interpretation.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
- Standalone Study: No, a standalone performance study was not done as this is not an algorithm or an AI device.
Explanation: This device is a physical component (a cassette) for mammography, not an algorithm. Therefore, a standalone algorithm performance study is not relevant.
7. Type of Ground Truth Used
- Type of Ground Truth: Not applicable. No "ground truth" (such as expert consensus, pathology, or outcomes data) was used in the context of a clinical performance study for this device. The "ground truth" for the submission is based on engineering specifications, material characteristics, and conformity to voluntary standards for film cassettes.
Explanation: The "safety and effectiveness" conclusion for this device is based on its engineering design, materials, and its ability to meet published industry standards for film cassettes (e.g., maintaining light-tightness and intimate film-screen contact), as well as its substantial equivalence to an existing predicate device. This does not involve clinical diagnostic ground truth.
8. Sample Size for the Training Set
- Sample Size: Not applicable. There is no mention of a training set as this is not an AI/ML device.
Explanation: As this is not an AI/ML device, the concept of a "training set" for an algorithm is not relevant.
9. How the Ground Truth for the Training Set Was Established
- Ground Truth Establishment: Not applicable.
Explanation: Since there was no training set, there was no ground truth established for one.
Summary of this 510(k) Submission:
This 510(k) submission for the Ferrania LifeRay™ Mammo Cassettes is a "substantial equivalence" filing. It demonstrates safety and effectiveness by:
- Technological Comparison: Highlighting that its components and function are similar to the predicate device (Kodak MIN-R 2 CASSETTE).
- Standards Conformance: Stating that the device conforms to relevant voluntary industry standards (ANSI PH1.49 1995 and ISO/FDIS 4090: 2000) for radiographic film cassettes.
Crucially, this type of submission does not involve clinical performance studies with patient data, human readers, or AI algorithms that would require the establishment of ground truth or the measurement of diagnostic performance metrics like sensitivity and specificity. The "acceptance criteria" are implied by the standards and the features of the predicate device, with the "study" being the engineering assessment and comparison presented in the submission.
