The device is used in generating digital signals from medical radiographs. The digital signals are intended for use in PACS and tele-radiology.
The device is a transparency, charge coupled device (CCD) scanner which can be used to digitize radiographs or X-ray film. The digitizer reads gray digital information from the image and sends the raw data file to a host computer, for use with a Picture Archiving and Communication (PAC) System or teleradiology software package currently in the market place as separately approved third party software packages or complete PAC system. The user interface for the film digitizer resides in the host application software program. The 960 creates a digital image file from transparent originals. The digital image file is expressed in either 8 or 12 bit grav level file format. The digitizer is connected to a host computer (either PC, Mac or UNIX) via SCSI II. There is no "activate" button the 960. To start an image capture operation, the user must activate the digitizer user interface on the host computer. Overall, The 960 uses a film fed drive which transports the film over the camera as it digitizes the image. Each scan line is captured by the charge coupled device (CCD). The scan line of data is normalized and calibrated to align the response from individual CCD receptors. The image data signal is converted from analog to digital format on the OCP board. The digital signal is then sent to the host via the SCSI II connection with the host computer.
The provided text describes a 510(k) summary for the Howtek 960 Film Digitizer. It outlines the device's characteristics and states that performance testing was conducted. However, the document does not contain specific details about acceptance criteria or the study that proves the device meets those criteria.
Instead, it makes a general statement: "The performance testing results for the 960 Film Digitizer demonstrated that the device meets its intended specifications and therefore, meets the requirements necessary for its intended use as a component of a PAC system or teleradiology software package." It also highlights that the 960 is superior in some performance characteristics (scan rates, density range, gray scale resolution, spatial resolving power) compared to its predicate device, the Howtek Scanmaster DX.
Therefore, I cannot fulfill your request for:
- A table of acceptance criteria and the reported device performance: This information is not present in the provided text.
- Sample size used for the test set and the data provenance: This information is not present.
- Number of experts used to establish the ground truth for the test set and their qualifications: This information is not present.
- Adjudication method: This information is not present.
- Multi-reader multi-case (MRMC) comparative effectiveness study: This type of study is not mentioned. The device is a film digitizer, not an AI-assisted diagnostic tool for human readers.
- Standalone performance: While the device is "standalone" in the sense that it digitizes films, the document does not present quantitative standalone performance metrics. It's a component, not an interpretative AI.
- Type of ground truth used: This information is not present.

Description of Device:
The device is a transparency, charge coupled device (CCD) scanner which can be used to digitize radiographs or X-ray film. The digitizer reads gray digital information from the image and sends the raw data file to a host computer, for use with a Picture Archiving and Communication (PAC) System or teleradiology software package currently in the market place as separately approved third party software packages or complete PAC system. The user interface for the film digitizer resides in the host application software program.
The 960 creates a digital image file from transparent originals. The digital image file is expressed in either 8 or 12 bit grav level file format. The digitizer is connected to a host computer (either PC, Mac or UNIX) via SCSI II. There is no "activate" button the 960. To start an image capture operation, the user must activate the digitizer user interface on the host computer.
Overall, The 960 uses a film fed drive which transports the film over the camera as it digitizes the image. Each scan line is captured by the charge coupled device (CCD). The scan line of data is normalized and calibrated to align the response from individual CCD receptors. The image data signal is converted from analog to digital format on the OCP board. The digital signal is then sent to the host via the SCSI II connection with the host computer.

Indications For Use:
The 960 reads gray information from the image and sends the raw digital data file to a host computer, for use with a Picture Archiving and Communication (PAC) System or teleradiology software package currently in the marketplace as a separately approved third-party software package. The re-user is responsible for detailing the Indications For Use for the PAC System (or teleradiology software package) as a whole, including the 960.
Contraindications
The 960 will be marketed as a component to the software development companies, who will incorporate the 960 into their respective PAC System or teleradiology software package. The software developer will be responsible for detailing the Contraindications for the PAC System (or teleradiology software package) as a whole, including the 960.
Potential Complications
The 960 will be marketed as a component to the software development companies, who will incorporate the 960 into their respective PAC System or teleradiology software package. The software developer will be responsible for detailing the Potential Complications for the PAC System (or teleradiology software package) as a whole, including the 960.
Technological Characteristics of Proposed and Predicate Devices
The proposed 960 has the same basic characteristics as the predicate Howtek Scanmaster DX. The DX is designed to digitize X-ray film or radiographs. In addition, the predicate scanner operates at lower scan rates, less density range, less gray scale resolution and less spatial resolving power. The 960 is superior to all of the listed predicate devices.
Performance Characteristics
The performance testing results for the 960 Film Digitizer demonstrated that the device meets its intended specifications and therefore, meets the requirements necessary for its intended use as a component of a PAC system or teleradiology software package.

Section VII
Conclusion
Based on the information presented in this Premarket Notification, Howtek, Incorporated believes that the proposed 960 Film Digitizer is substantially equivalent to the Scanmaster DX Film Digitizer. The 960 is equivalent to the predicate film digitizer in regard to its intended use ( i.e. it captures X-ray films or radiographs as part of a PAC System or teleradiology software package). The technological characteristics are substantially equivalent in that they are both CCD based film digitizers. The performance characteristics show that the 960 has better range and better resolution that the predicate device, therefore, is more than capable of providing equivalent performance to the DX.
