Intended Use

The fMRI Hardware System is a stimulus presentation and response collection system intended to be used by trained professionals to facilitate auditory and visual stimulation to be used in functional MR Imaging (fMRI) based on BOLD contrast. The visual system allows video signals from the stimulus presentation PC to enter the shielded scanner room and to be presented to the patient through a set of coil mounted displays (VisualSystemHD) or by an in-room LCD monitor.

Device Story

System facilitates fMRI studies by providing synchronized auditory/visual stimuli and collecting patient responses. Components: AudioSystem (headphones/mic), VisualSystem (coil-mounted displays or LCD monitor), ResponseGrips (handheld buttons), SyncBox (timing synchronization), and nordicAktiva (stimulus presentation software). Used in MRI suites by trained professionals (technicians/physicians). SyncBox connects to MR scanner to receive timing pulses, ensuring stimulus presentation aligns with image acquisition. Patient responses via grips are recorded by nordicAktiva. Fiber optics transmit signals into shielded scanner rooms. Output allows clinicians to provoke brain activity for BOLD contrast imaging, aiding in cognitive function investigation and pre/post-operative brain tumor mapping.

A synchronization module synchronizes the stimulus presentation software with the MR scanner. The System consists of five subsystems: AudioSystem, VisualSystem, ResponseGrip, SyncBox and nordicAktiva. The system is used for fMRI studies. fMRI stands for functional Magnetic Resonance Imaging. This technique is useful when determining certain diseases, gaining more information about a patient's condition or investigating cognitive functions. The technique is also used for examining the area of the brain affected in patients suffering from a brain tumor in both the pre-operative and post-operative stages. The System is used to present the stimulus necessary to provoke physiological processes in the brain. Visual [VisualSystem] and auditory [AudioSystem] stimulus and manual responses from the patient [ResponseGrips] are of primary interest. The timing of the visual and audio stimulation is critical to make sure that the correct MR image of the brains activity is linked to the stimulus presented. A synchronization unit [SyncBox], connected between the MR-scanner and the stimulus presentation {5}------------------------------------------------ software [nordicAktiva], is included in the system to make sure that the synchronization is correct. Image /page/5/Figure/1 description: The image shows a diagram of a system with several components, including a SyncBox, nordic Aciva, ResponseGrip Interface, and Communication Console. The SyncBox is connected to a "Trigger Pulse (MR scanner)" within a "Technical Room". The nordic Aciva is connected to the SyncBox, ResponseGrip Interface, and Communication Console, with "Audio" and "Video" connections to the console. The diagram also shows an LCD screen and a person inside a scanner, with "Video" and "Audio" connections to the Communication Console. Figure 1 presents the complete configuration of the fMRI Hardware System. All signals entering or leaving the scanner room are received and transmitted by use of fiber optics. The system allows video and audio signals from the stimulus PC to enter the shielded scanner room and to be presented to the MR. The subject responds to the stimulus by using the handheld grips. ## 9.3 Sub-system components and description #### 9.3.1 VisualSystem The VisualSystem allows video signals from the stimulus presentation PC to enter the shielded scanner room and to be presented to the patient through a set of coil-mounted displays [VisualSystem HD] or by an in-room LCD monitor. #### 9.3.2 Audio System The AudioSystem allows auditory signals from the stimulus presentation PC to enter the scanner room and to be presented to the patient wearing a set of headphones. A communication console allows the operator to adjust the sound from the PC and to speak directly to the patient through a built-in microphone. #### 9.3.3 ResponseGrip The purpose of this component is to collect patient responses during an fMRI study. The ResponseGrip consists of two hand-held grips with two buttons each. By pressing the patient can respond to the presented stimulus. The ResponseGrip is connected to an optical-electrical adapter which converts {6}------------------------------------------------ light to electrical signals. The electrical signal is fed to the Stimulus PC by using standard PC communication interfaces. ### 9.3.4SyncBox The SyncBox is connected directly to the MRI scanner where it receives timing pulses sent out with each image series and demodulates this signal before it's forwarded to the stimulus PC. In this way one can ensure that the stimulus presentation software is synchronized with the MRI image recordings. ## 9.3.5nordicAktiva nordicAktiva is a software that generates visual and auditory stimulus to the patient. The stimulus presentation is synchronized with the scanner through the SyncBox and presented to the patient through the VisualSystem and AudioSystem. nordicAktiva records the responses fed to the Stimulus PC from the ResponseGrip, as well as the synchronization pulses from the SyncBox. # 9.4 Identification of Change to Unmodified Device The VisualSystem will be updated with a new version of the coil mounted displays [VisualSystem HD] for attachment to the MR head coil. The brand name for the new version is VisualSystem HD. The same video signal can be presented on the VisualSystem HD and the in-room LCD-monitor that was cleared in K092253. The operator has the choice to use either the VisualSystem HD or the in-room LCD monitor as before. ## 9.4.1 Technological Characteristics and Substantial Equivalence To summarize, the modified fMRI Hardware System is found substantial equivalent to the previously cleared device. The modified system only has a new device added to display video. The indications for use for the modified fMRI Hardware System have remained unchanged. | Changes: | fMRI Hardware System, K092253 [Coil Mounted Displays] | Modified fMRI Hardware System [VisualSystem HD] | |--------------------|-------------------------------------------------------------|----------------------------------------------------| | Display Resolution | 800x600 pixels | 1920x1200 pixels | | Video source | VGA - Standard PC video output | HDMI - Standard PC video output | | EyeTracking | Separate unit | Integrated | The rationale for determining the substantial equivalence between the previously cleared device and the modified fMRI Hardware System is based on the defined intended use, indications for use, and the technical and operational characteristics. To verify that the modified device fulfils the defined characteristics and requirements, it has been subject to extensive in-house and lab testing. The successful completion of said tests verifies the claimed characteristics of the modified fMRI Hardware System, and thus supports the determination of substantial equivalence. {7}------------------------------------------------ ## 9.5 Summary of Testing The fMRI Hardware System has been tested for function, biocompatibility and safety and fulfills all requirement specifications. #### 9.5.1 Functional test All functional testing was carried out as per internal test protocols. Testing involved performance and bench testing. #### 9.5.2 Biocompatibility test results The direct components of applied parts contacting with the users in the VisualSystem HD were tested for the following: In Vitro cytotoxicity - Cytotoxicity testing was carried out in accordance to ISO 10993-5:2009 Biological Evaluation of Medical Devices – Part 5: Tests for In Vitro Cytotoxicity.
