Model CTS-415 is a linear/convex electronic scanning ultrasonotomograph with a built-in digital scan converter (DSC) and main CPU module. The unit allows heart, abdominal organic and fetal tomographic images to be observable on a video monitor. The main unit is portable and is separable from other equipment to be carried for its use at another place as well as being usable in combination with a 9inch video monitor and a special photographic unit.
The provided 510(k) Premarket Notification for the CTS-415 with C3I40 and L7I50 Transducers focuses on demonstrating substantial equivalence to a predicate device (Hitachi Medical Corporation EUB-310, K862867). This type of submission relies on showing that the new device has similar technological characteristics and performs comparably to a device already cleared by the FDA, rather than proving novel effectiveness through clinical trials with specific acceptance criteria and outcome measurements.
Therefore, the document does not contain the detailed information requested about acceptance criteria, study design, sample sizes, expert ground truth establishment, or specific performance metrics in the way one would find for a de novo submission or a device claiming superiority.
Specifically, the document does not include:
- A table of specific acceptance criteria or reported device performance against such criteria.
- Information on a "test set" sample size, data provenance, number or qualifications of experts, or adjudication methods for ground truth because such a study design is not described.
- A multi-reader multi-case (MRMC) comparative effectiveness study or any effect size for human readers with/without AI assistance, as AI functionality is not mentioned for this device.
- A standalone (algorithm only) performance study.
- The type of ground truth used (e.g., pathology, outcomes data) for a study, as no such study is detailed.
- Sample size for a training set or how ground truth for a training set was established, as machine learning or AI models requiring such sets are not described.
Summary based on the provided document:
The device, "CTS-415 with C3I40 and L7I50 Transducers," is a Diagnostic Ultrasound System. Its acceptance for marketing by the FDA (K013327) is based on demonstrating substantial equivalence to the predicate device, Hitachi Medical Corporation EUB-310 (K862867).
The document lists the device's technological characteristics (e.g., scanning methods, display modes, frequency of probes, image adjustments, measuring functions) and its intended uses for various clinical applications (Fetal, Abdominal, Pediatric, Small Organ, Cardiac, Peripheral Vascular) in B and M modes, with the C3I40 and L7I50 transducers supporting specific subsets of these applications.
The "acceptance criteria" in this context are implicitly met by demonstrating that the device's technological characteristics and stated intended uses are substantially equivalent to a legally marketed predicate device. The FDA's letter explicitly states that the determination of substantial equivalence means the device can be marketed, subject to general controls and requirements for a post-clearance special report on acoustic output measurements. This process does not involve setting quantitative performance metrics like sensitivity, specificity, or accuracy against a pre-defined threshold in a clinical study as typically seen with de novo submissions for novel devices or AI/ML-enabled devices.

Trade Name: CTS-415 Ultrasound Imaging System Regulation Number: 21 CFR 892.1560 Regulation Name: Ultrasonic pulsed echo imaging system Product Code: 90 IYO Reagulation Number: 21 CFR 892.1570 Regulation Name: Diagnostic ultrasound transducer Product Code: 90 ITX Regulatory Class: II Dated: August 24, 2001 Received: October 5, 2001
Dear Mr. Leiker:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling. and prohibitions against misbranding and adulteration.
This determination of substantial equivalence applies to the following transducers intended for use with the CTS-415 Ultrasound Imaging System, as described in your premarket notification:
Transducer Model Number
3.5 MHz C3I40 Curved Array Probe 7.5 MHz L7150 Linear Array Probe
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device
{3}------------------------------------------------
can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807): labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This determination of substantial equivalence is granted on the condition that prior to shipping the first device, you submit a postclearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in Appendix G. (enclosed) of the Center's September 30, 1997 "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers." If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.
The special report should reference the manufacturer's 510(k) number. It should be clearly and prominently marked "ADD-TO-FILE" and should be submitted in duplicate to:
Food and Drug Administration Center for Devices and Radiological Health Document Mail Center (HFZ-401) 9200 Corporate Boulevard Rockville, Maryland 20850
This letter will allow you to begin marketing your device as described in your premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus permits your device to proceed to market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801, please contact the Office of Compliance at (301) 594-4591. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

§ 892.1560 Ultrasonic pulsed echo imaging system.
(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
