The Mobile X-ray Unit Sirius Starmobile tiara is a general radiography system and is composed of the X-ray high voltage generator, X-ray tube, support unit, and digital radiograph device (DR-ID 800) made by Fujifilm Corporation.

This device is designed for pediatric and adult patients.

It is intended for use in general radiography of the head, body, or extremities including pediatric exams. The device output can provide an aid to diagnosis when used by a qualified physician.

Device Description

The Sirius Starmobile tiara battery powered, mobile x-ray system features a built-in Flat Panel Detector System: DR-ID800 which is a modification of the FDR D-EVO Flat Panel Detector System (DR-ID600), K132509. Because the Flat Panel Detector System is incorporated in the mobile equipment, the images are available to the technologist in a very short time, allowing the technologist to assure the exam has been performed adequately, minimizing return trips. Wireless communication is available, as an option, for updates to the patient worklist from the RIS/HIS.

The Sirius Starmobile tiara provides smooth and quiet motorized travel capability via rear wheels independently driven by dual motors, a versatile radiography range through the pantograph arm, and easy-to-operate positioning of flat detector providing sharp image quality with a short exam completion time.

AI/ML Overview

The provided document is a 510(k) premarket notification letter for the Sirius Starmobile tiara, a mobile x-ray system. It does not contain information about acceptance criteria or a study proving its performance against such criteria for an AI/CAD/software device.

The document focuses on:

Regulatory clearance: The FDA's determination of substantial equivalence to a predicate device (Carestream DRX-Revolution Mobile X-ray System, K120062).
Device description and intended use: General radiography for head, body, or extremities for pediatric and adult patients.
Non-clinical testing: Compliance with various IEC and AAMI ANSI standards related to medical electrical equipment, safety, electromagnetic compatibility, radiation protection, usability, and software life cycle processes.
Technological characteristics comparison: Discussion of similarities and minor differences (e.g., target angle, anode heat capacity, detector pixel size) between the subject device and the predicate device, concluding overall substantial equivalence.
Clinical testing snippet: Mentions "sample clinical images in Section 10 Performance" but provides no details on how they were used to define or meet acceptance criteria, study design, or metrics.

Therefore, I cannot extract the requested information (acceptance criteria, study details, sample sizes, ground truth, expert qualifications, etc.) as it is not present in the provided text. This document is a regulatory clearance letter, not a detailed performance study report.

Device Description

Device Technological Characteristics

The Sirius Starmobile tiara is substantially equivalent to the predicate device, the Carestream DRX-Revolution Mobile X-ray System. The Sirius Starmobile tiara and the Carestream DRX-Revolution Mobile X-ray System both consist of an x-ray generator, x-ray tube, collimator, and graphical user interface on an operator console with touch screen monitor. These components are mounted on a motorized cart that is battery powered to enable the device to be moved from location to location. Both systems utilize a digital flat panel detector for image capture and can also be used to expose CR storage phosphor or film cassettes. Both systems have operator console software with image processing capability.

Summary of Clinical/Non-Clinical Testing

Non-Clinical Testing

The Sirius Starmobile tiara was subjected to the following laboratory testing:

AAMI ANSI ES60601-1:2005/(R) 2012 and A1:2012, C1:2009/(R)2012 and A2:2010/(R)2012 ● Medical electrical equipment - Part 1: General requirements for basic safety and essential performance (IEC 60601-1:2005, MOD)
o IEC 60601-1-2 Edition 3: 2007 Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic compatibility - Requirements and tests

IEC 62304 Edition 1.0, Medical device software Software life cycle processes .

Clinical Testing

The Sirius Starmobile tiara System submission includes sample clinical images in Section 10 Performance.

Substantial Equivalence

Both the Sirius Starmobile tiara System (subject device) and the predicate device have the identical intended use for examinations of adult and pediatric patients over all parts of the body.

The key technological characteristics between the subject device and the predicate are substantially equivalent.

In regards to the x-ray tube, the subject device has a larger target angle, but the focal spot size is the same as the predicate, so beam coverage is equivalent. Anode heat capacity is less, but in mobile use the number of exams are less than conventional x-ray, so the lower heat capacity will not impact the ability to perform exams.

X-ray tube head movement is comparable between the subject device and the predicate. The maximum SID to floor is similar, but the subject device has a wider range of movement from the floor. While tube arm reach is slightly less than the predicate, all other motions of the subject device have a wider range.

All the detectors available for the subiect device have comparable sizes to the predicate. Detector pixel size of the subject device (0.150mm) is within the tvpical range for general radiography (0.139 to 0.200mm). Section 10, Performance, shows bench test results and sample clinical data indicating that the subject device covers the range of body and extremity imaging, with acceptable image quality, as compared to general mobile radiography applications available on the predicate device and others in its class.

{5}------------------------------------------------

Conclusions

It is the opinion of Hitachi Medical Systems America, Inc. the Sirius Starmobile tiara is substantially equivalent with respect to hardware, base elements of the software, safety, effectiveness, and functionality to the Carestream DRX-Revolution Mobile X-ray System (K120062).
