The document describes a digital replacement for film/cassette systems for radiation therapy imaging. It mentions image processing but does not mention AI, ML, or any related technologies. The performance studies focus on comparing the digital system to film-based systems in terms of image quality and dose linearity.
No.
The device is used for imaging and localization in radiation therapy planning and quality control, not for directly treating a disease or condition.
No
This device is an accessory to megavoltage radiation therapy systems, primarily used for portal localization imaging and to aid in radiation therapy planning and quality control. It is a digital replacement for conventional film/cassette imaging systems, designed to acquire images for therapeutic purposes, not for diagnosing medical conditions.
No
The device is a physical cassette with lead and a compression plate designed to hold an imaging plate. While it interacts with software for image processing, the core device described is hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for radiation therapy portal localization imaging, planning, and quality control. This involves imaging the patient's anatomy to ensure accurate delivery of radiation therapy.
- Device Description: The device is a cassette and imaging plate system used with radiation therapy systems (linear accelerators or cobalt 60 units) to capture images. It's a digital replacement for conventional film/cassette systems used in this context.
- Lack of IVD Characteristics: An IVD device is used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not interact with or analyze such specimens. It's used for imaging the patient directly during a medical procedure (radiation therapy).
The device is clearly intended for use in a clinical setting for medical imaging related to radiation therapy, not for in vitro diagnostic testing.

Device Description
The Fuji IP Cassette Type PC will be used as an accessory to medical charged particle radiation therapy systems providing radiation therapy (portal localization) imaging. The Fuji IP Cassette Type will be used with a FDA-cleared radiation treatment linear accelerator or cobalt 60 unit. The Type PC cassette is a digital replacement technology for conventional film/cassette imaging systems. This cassette is appropriate to accommodate energies up to 18 MV and higher.
Due to the high dose rates associated with this oncology indication, a 0.5 mm lead (Pb) absorber was added to the front of the cassette. In addition, a compression plate was added to the back of the cassette to place the imaging plate (IP) in contact with the lead cassette front during exposure. The compression mechanism was developed to maintain contact between the cassette front and IP during exposure to ensure maximum resolution and contrast.
Instead of film, a Fuji Imaging Plate (IP) is loaded into the cassette for exposure. Before exposure, the compression plate is engaged by moving the thumb sliders on the cassette to the EXPOSE position. After exposure, the compression plate is returned to its retracted position by moving the slide button from the EXPOSE position to the READER position. The cassette is then inserted into the appropriate Fuji image reader for scanning. After processing the IP in the CR reader, the IP is erased and returned to the cassette for reuse. No new software modifications to the CR reader or workstation are needed for this indication.
The imaging plate is processed in the CR reader according to exam and user-specified parameters. Images are processed using currently-cleared MFP image processing with FNC applied. The resulting image may be displayed on a cleared CRT or LCD monitor, printed by a hard copy device onto film, or output to a cleared diagnostic workstation, optical disk file, PACS or therapy planning workstations that accepts DICOM images. FDA has cleared Fuji's imaging plate, image readers, and image processing applications in previous 510(k)s.
Note: Fuji Imaging Plates (IP) belonging to the Type ST (Standard) family, are to be used for this product.
The Fuji IP Cassette Type PC is offered in three sizes: 14"x17" (35 x 43 cm), 14"x14" (35 x 35 cm), and 10"x12" (25 x 30 cm).

CR reader, the IP is erased and returned to the cassette for reuse. No new software modifications to the CR reader or workstation are needed for this indication.
The imaging plate is processed in the CR reader according to exam and user-specified parameters. Images are processed using currently-cleared MFP image processing with FNC applied. The resulting image may be displayed on a cleared CRT or LCD monitor, printed by a hard copy device onto film, or output to a cleared diagnostic workstation, optical disk file, PACS or therapy planning workstations that accepts DICOM images.

Note: Fuji Imaging Plates (IP) belonging to the Type ST (Standard) family, are to be used for this product.
The Fuji IP Cassette Type PC is offered in three sizes: 14"x17" (35 x 43 cm), 14"x14" (35 x 35 cm), and 10"x12" (25 x 30 cm).
Intended Use
The Fuji IP Cassette Type PC will be used as an accessory to megavoltage radiation therapy systems providing radiation therapy portal localization imaging and to aid in radiation therapy planning and quality control.
The Fuji IP Cassette Type PC and imaging plate is a digital replacement technology for conventional film/cassette imaging systems.
Technological Characteristics
The subject device is an accessory to a medical charged particle radiation therapy system. The concept of radiographic cassettes and digital imaging are not new; there are several cleared digital imaging cassettes used for this indication on the market. The radiographic technique is unchanged from that of a film/screen based portal imaging application.
In addition, the proposed device has the same technological characteristics as the above-listed predicate device.
Testing
The following tests were performed at West Virginia University Hospitals Radiation therapy department to compare Fuji's IP Cassette Type PC (digital) to Kodak's EC-L (screen film cassette).
Dose Linearity Bench Test: Testing was performed to confirm that the Fuji IP Cassette Type PC (Portal Imaging Cassette) has the desired log-linear response between dose and mean pixel value. Test result passed. The results also indicate that the response is independent of energy between 6 and 18 MV.
Varian PortalVision™: Contrast-Detail phantom Test Bench testing was performed on both cassettes to assess image quality through the use of a Varian PortalVision™ Phantom. Images were scored by three independent observers with the following results:
- . 6MV- All three observers scored the Fuji CR image higher than the film image at the 6 MV energy range with a total score of 14.83 for the Fuji CR image vs. a 13.33 score for the Kodak film image.

FUJIFILM Medical Systems, USA, Inc. Fuji IP Cassette Type PC 510(k)
- 18MY- Two out of three observers scored the Fuji CR image equal to or superior to the . film image, with one observer scoring the Kodak film image 0.5 higher than the Fuji CR image. The average score for both systems is the same (9.0).
Varian Portal Vision™ Phantom with Anthropomorphic Phantom Test: Clinical testing was performed by placing the Varian PortalVision™ Phantom underneath the anthropomorphic phantom to obtain images in order to compare the standard port film cassette with Fuji's IP Cassette Type PC (portal imaging cassette).
Images were scored by three independent observers with the following results:
- Under the same exposure conditions at 6 MV. the Fuji CR image was scored equivalent . (FCR judged slightly superior by 2 of 3 reviewers) to the Kodak film image when scoring the Varian Portal Vision™ phantom with the superimposed anthropomorphic image.
- . Under the same exposure conditions at 18 MV, the Fuji CR image is judged superior to the Kodak film image when scoring the Varian Portal Vision™ phantom with the superimposed anthropomorphic image.
Sample images are enclosed in this 510(k) in Attachment 1.
Conclusion
This 510(k) premarket notification submission has demonstrated Substantial Equivalence as defined and understood in the Federal Food Drug and Cosmetic Act and various guidance documents issued by the Center for Devices and Radiological Health. We conclude the subject device to be as safe and effective as the predicate devices.
