Intended Use
Intended for use by a qualified/trained physician or technician for the purpose of acquiring X-ray images of the desired parts of patient's anatomy (including head, cervical spine, chest, abdomen, lumbar spine, pelvis and extremities).This device is not intended for mammography.
Device Description
This SR-2300/SR-2300S Portable DR Imaging System is a portable digital device developed, designed and manufactured by SIUI. The device consists of the following major components: a portable X-ray unit, a flat panel detector, and workstation. The difference between SR-2300 and SR-2300S is the operation interface of the portable X-ray Unit only, while the flat panel detector and the workstation are the same for SR-2300 and SR-2300S. The SR-2300S has the display interface with button-operation digital tube, while the SR-2300 has the display interface with touch screen operation.
More Information

No
The summary describes a standard portable digital X-ray system with a flat panel detector and workstation. There is no mention of AI, ML, or any related concepts in the device description, intended use, or performance studies. The focus is on image acquisition and processing, which is typical for digital radiography systems and does not inherently imply AI/ML.

No
The device is used for acquiring X-ray images, which is a diagnostic purpose, not a therapeutic one.

Yes
The device is used for "acquiring X-ray images of the desired parts of patient's anatomy," which are then reviewed to make diagnostic decisions.

No

The device description explicitly lists hardware components: a portable X-ray unit, a flat panel detector, and a workstation. This indicates it is a hardware system with integrated software, not a software-only medical device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to acquire X-ray images of a patient's anatomy. This is a diagnostic imaging device, not a device used to examine specimens derived from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
  • Device Description: The device consists of an X-ray unit, flat panel detector, and workstation. These are components of an imaging system, not an in vitro diagnostic system.
  • Input Imaging Modality: The input is X-ray, which is an imaging modality, not a method for analyzing biological samples.

IVD devices are specifically designed to perform tests on samples taken from the body, not to image the body itself.

Device Description

This SR-2300/SR-2300S Portable DR Imaging System is a portable digital device developed, designed and manufactured by SIUI. The device consists of the following major components: a portable X-ray unit, a flat panel detector, and workstation. The difference between SR-2300 and SR-2300S is the operation interface of the portable X-ray Unit only, while the flat panel detector and the workstation are the same for SR-2300 and SR-2300S. The SR-2300S has the display interface with button-operation digital tube, while the SR-2300 has the display interface with touch screen operation. Except for the difference above, the 2 models (SR-2300 and SR-2300S) are completely the same in all the other mechanical and circuit design.

The major components of the X-ray main unit include: handle, enclosure, control panel, system control (SYS) board, high-voltage tank, collimator (beam limiter), lithium-ion battery and system control software running on the SYS board.

The system control software is for real-time interaction and control with various circuit modules inside the Portable DR Imaging System. The software responds to user operations on the control panel. The user can adjust and control the kV and mAs parameters, and the software will display the parameters or directly load the APR parameters. The software loads the control data from X-ray output into the high-voltage generation control circuit of the system control board, and control the high-voltage tank to generate high-voltage to excite the X-ray tube inside to emit X-rays, control the switch of the collimator indicator, and monitor the working status of the device, the battery power status, and control the display of the status indicators. The system is for X-ray imaging and diagnosis in facilities with mobile or fixing sites. Since the kV range of this device is 40~125kVp, which is not suitable for breast exams, the device is not intended for mammography.

The flat panel detector is the core of image acquisition of the system. The X-ray emitted through the human body is converted by the scintillator of flat panel detector to visible optical signals, which are then converted to digital signals by the amorphous silicon of flat panel detector. The processed digital signals are sent to the image workstation for image reconstruction, display, storage and transmission via a Gigabit Ethernet cable. The image workstation is installed with a PIE-5 DR Workstation, which is the core of image acquisition and processing on the system.

Software Description 5.8

The SR-2300/SR-2300S Portable DR Imaging System contains two software, one is the embedded software in the X-ray unit: system control software, and the other is PIE-5 DR Workstation (herein after referred to as "PIE-5").

The system control software of SR-2300/SR-2300S is new software designed by SIUI. The software adopts development languages of keil, the program language is C language, the hardware platform is ARM. The system control software is for real-time interaction and control with various circuit modules inside the Portable DR Imaging System. The software responds to user operations on the control panel. The user can adjust and control the kV and mAs parameters, and the software will display the parameters or directly load the APR parameters. The software loads the control data from X-ray output into the high-voltage generation control circuit of the system control board, control the high-voltage tank to generate high-voltage to excite the X-ray tube inside to emit X-rays, control the switch of the collimator indicator, monitor the working status of the device and the battery power status, and control the display of the status indicators. The Level of Concern for the Software Device is Moderate.

The programming language of PIE-5 is C language, and the operating platform is Microsoft Windows. The software is a medical image processing system, consisting of image acquisition, image review and diagnosis, image processing and digital storage functions, which mainly address digital image workflow in radiographic department of hospitals. The functions of the software include patient registration, image acquisition and processing, image review and diagnosis, image printing, report editing and PACS transmission, digital image storage and recovery. The Level of Concern for the Software Device is Moderate.

5.9 Clinical Testing

Clinical testing is not necessary for the SR-2300/SR-2300S Portable DR Imaging System in order to demonstrate substantial equivalence to the predicate device.

5.10 Label

The labels on the device show that this device conforms to the following:

11

21 CFR 1020 Subchapter J: Performance Standards for Ionizing Radiation Emitting Products.

21 CFR 1020.30: Diagnostic x-ray systems and their major components,

  • 21 CFR 1020.31: Radiographic Equipment .

5.11 Conclusion

The subject device SR-2300/SR-2300S system and the predicate device are comparable in terms of technical features, general functions, applications and indications for use.

Compared with the predicate device, the power of the SR-2300/SR-2300S is higher. The SR-2300/SR-2300S can be used for imaging including head, cervical spine, chest, abdomen, lumbar spine, pelvis and extremities, and the predicate device AcuityPDR can be used for both adult and pediatric subjects for taking diagnostic x-rays. Nevertheless, it does not affect the safety and effectiveness of the SR-2300/SR-2300S, nor does it change the indications for use of the SR-2300/SR-2300S unit.

The indications for use of the SR-2300/SR-2300S Portable DR Imaging System do not create new potential safety risks, and its performance is comparable as that of the marketed products. Therefore, the device is as safe and effective as the legally marketed predicate device.
