SEDECAL X-PLUS LP PLUS DIGITAL DIAGNOSTIC X-RAY SYSTEMS
These Digital Radiographic Systems are intended for use by a qualified/trained doctor or technician on both adult and pediatric subjects for taking diagnostic radiographic exposures of the skull, spinal column, chest, abdomen, extremities, and other body parts. Applications can be performed with the patient sitting, standing, or lying in the prone or supine position.
These digital diagnostic x-ray systems consist of a tubehead/collimator assembly mounted on a U-Arm, along with a generator, generator control, and an x-ray table. Power ratings for the available generators are in the rage of 50 kw to 80 kW. Exposure voltage range varies from 40 - 125 KV or 40 - 150 kV, with current of 300 - 100 mA. Exposure time is 1 ms - 10 s. This device represents a new combination of already cleared Sedecal and Canon products.
The provided 510(k) summary for the Sedecal X-Plus LP Plus Digital Diagnostic X-Ray System (K090238) does not contain the information requested regarding acceptance criteria and a specific study proving the device meets those criteria, as you would typically expect for performance data of AI/CADe devices.
This submission is for a traditional X-ray system, and the approval is based on substantial equivalence to predicate devices, rather than a performance study with defined acceptance criteria for diagnostic accuracy.
However, I can extract and infer some information based on the document's content:
1. Table of Acceptance Criteria and Reported Device Performance:
- Acceptance Criteria: For this type of device, the acceptance criteria are generally related to demonstrating substantial equivalence to existing legally marketed devices, primarily focusing on safety and effectiveness through comparison of technical characteristics and adherence to relevant performance standards.
- Reported Device Performance: The document states, "The results of bench and test laboratory indicates that the new device is as safe and effective as the predicate devices."
Acceptance Criteria Category | Reported Device Performance |
---|---|
Intended Use | Met: Same intended use as predicate devices: diagnostic radiographic exposures of skull, spinal column, chest, abdomen, extremities, and other body parts for adult and pediatric subjects, in various patient positions. |
Configuration | Met: Similar configuration (U-Arm mount only) to predicate K062335. Differs from K042876 (U-Arm or Ceiling Suspension) but is considered a minor technological difference not impacting safety/effectiveness. |
Positioning Controls | Met: "Enhanced, same as X Plus LP Plus" (predicate K062335), an improvement over K042876's "Standard" but still within the scope of safe and effective operation for an X-ray system. |
Performance Standard | Met: Adheres to 21 CFR 1020.30 (Performance standards for ionizing radiation emitting products - radiographic equipment). This is a statutory requirement for all such devices. |
Generator | Met: High frequency made by Sedecal, same as both predicate devices. |
Collimator | Met: Manual (Ralco) or Automatic (Huestis). Offers an automatic option, which is an enhancement over the manual-only collimators of the predicate devices but is a common and accepted component in X-ray systems. |
Image Acquisition | Met: Utilizes CANON panels (multiple models: 50C, 50G, 40C & 40G). This is a key technological difference from predicate K062335 (Film) and an update from K042876 (Digital CANON 50G). The use of cleared Canon digital panels (referenced by K numbers K060433, K031633, K031447, K023750) demonstrates their established safety and effectiveness. |
Electrical Safety | Met: Adheres to IEC-60601 UL listed. This is a standard safety requirement for medical electrical equipment. |
Overall Conclusion | "as safe and effective as the predicate device, have few technological differences, and has no new indications for use, thus rendering them substantially equivalent to the predicate devices." |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- This information is not provided in the document. The approval is based on "bench and test laboratory" results and comparison of specifications, not a clinical test set with patient data for diagnostic accuracy assessment.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not applicable/provided. No clinical reader study or ground truth establishment relevant to diagnostic accuracy is described.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- This information is not applicable/provided.
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:
- No, an MRMC comparative effectiveness study was not done. This device is a digital X-ray system, not an AI or CADe device designed to assist human readers or provide diagnostic interpretations.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- No, a standalone performance study was not done. This is an imaging acquisition device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- Not applicable. The "ground truth" for this submission revolves around engineering performance verified by "bench and external laboratory testing to applicable standards" (e.g., 21 CFR 1020.30, IEC-60601) to demonstrate the device functions as intended and is safe. It's not about diagnostic accuracy.
8. The sample size for the training set:
- Not applicable. This isn't an AI/machine learning device that requires a training set.
9. How the ground truth for the training set was established:
- Not applicable.

SEDECAL X PLUS LP PLUS
The SEDECAL X PLUS LP PLUS Universal Radiographic Systems are intended for use by a qualified/trained doctor or technician on both adult and pediatric subjects for taking diagnostic radiographic exposures of the skull, spinal column, chest, abdomen, extremities, and other body parts. Applications can be performed with the patient sitting, standing, or lying in the prone or supine position.
SEDECAL X PLUS LP PLUS Universal Radiographic Systems are stationery units which operate from 120 or 220 V 50-60~ AC. The units utilize high frequency inverters. The usual safety precautions regarding the use of x-rays must be observed by the operator. This modified device employs new controls, including a touch screen and an infrared remote.
This K062335 510(k) summary describes a submission for a modified medical device rather than a new device with novel performance claims directly tied to specific acceptance criteria and study results. Therefore, the standard format for presenting acceptance criteria, device performance, and detailed study information for AI/algorithm performance is not fully applicable or derivable from the provided text.
Here's why and what information can be extracted:
The submission is for the SEDECAL X PLUS LP PLUS Universal Radiographic Systems, which is a stationary X-ray system. The core of this 510(k) is to demonstrate substantial equivalence to a predicate device (Sedecal URS X-Ray Units K012546), focusing on changes to the user interface (touch screen and infrared remote) and ensuring the safety and effectiveness are maintained.
When a 510(k) relies on substantial equivalence for modified devices, the "study" often involves bench testing, user testing, and adherence to performance standards to show that the modifications do not introduce new safety or effectiveness concerns, and that the device performs as well as the predicate device. It doesn't typically involve a comparative effectiveness study with AI or a standalone algorithm performance study with specific metrics like sensitivity/specificity against a ground truth.
Therefore, many sections of your requested output will be marked as "Not Applicable" or "Not Provided in Document."

Notes on Acceptance Criteria:
- The primary "acceptance criteria" here are demonstrating substantial equivalence, meaning the modified device performs comparably to the predicate in terms of safety and effectiveness, especially given the "new controls, including a touch screen and an infrared remote."
- "Bench, user, and standards testing" are the methods used to meet these criteria, rather than a clinical study with calculated performance metrics.
2. Sample size used for the test set and the data provenance
- Sample Size: Not provided in the document. For device modifications like this, "user testing" might involve a small number of typical users to evaluate the new interface, but specifics are not disclosed. "Bench testing" refers to engineering and quality assurance tests. "Standards testing" refers to compliance with regulatory standards.
- Data Provenance: Not provided in the document.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not Applicable / Not Provided. This type of information is relevant for AI algorithms interpreting medical images or data, where expert consensus often establishes ground truth. For a stationary X-ray system, experts (engineers, quality control personnel) would evaluate the device's functionality, safety, and image quality (which is assumed to be equivalent to the predicate). There is no "ground truth" in the diagnostic sense being established in this submission.
4. Adjudication method for the test set
- Not Applicable / Not Provided. Adjudication methods (e.g., 2+1, 3+1) are typically used in studies where multiple human readers or algorithms are evaluating cases and their interpretations need to be reconciled to form a definitive "ground truth." This submission focuses on engineering and regulatory compliance, not diagnostic interpretation studies.
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
- No, an MRMC comparative effectiveness study was not done. This type of study is specifically designed for AI-assisted diagnostic devices to evaluate the impact of AI on human reader performance. The device described here is a basic X-ray system, not an AI diagnostic tool.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
- No, a standalone algorithm performance study was not done. This device is an X-ray machine, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Not Applicable in the context of diagnostic performance. For this device, "ground truth" relates to functional specifications and safety standards being met, as per engineering and regulatory requirements. For example, voltage outputs measured during bench testing would be compared against engineering specifications, which themselves are the "ground truth" for those tests. Image quality being "equivalent" to the predicate would be the "ground truth," likely established through physical phantom tests and possibly expert review, but not in the detailed diagnostic sense.
8. The sample size for the training set
- Not Applicable. This is an X-ray system, not a machine learning model that requires a training set.
9. How the ground truth for the training set was established
- Not Applicable. As there is no training set for an AI/ML algorithm.
