Imaging equipment for medical, dental and veterinary use

Tender description

Supply and installation of fMRI equipment in the MRI centres involved in SINAPSE, a consortium of Scottish universities aiming to create a strong dynamic network for a shared environment for strategic research development in brain imaging (http://www.sinapse.ac.uk/ ). Institutions include University of Edinburgh, University of Aberdeen, University of Glasgow and University of Dundee. Bidders must self-certify their adherence to selection and exclusion criteria via the ESPD (Scotland) on PCS-T. Suppliers may be required to submit Means of Proof at a later stage. The display must be a large screen (32 inches) with a resolution of 1920(H) by 1080(V) pixels and a refresh rate of at least 60Hz. The interfacing capabilities between the stimulation PC and the screen are of primary importance, in particular it must be specified how synchronization between the video card and the display is achieved (or if for instance there is a buffer to ensure a fixed delay). The eye tracker must be MRI compatible, up to 7 Tesla. It must have an acquisition rate of at least 60 Hz, have an easy interface with other fMRI related equipment. Importantly, training in setting up and acquire the data is also required at the installation. Eye glasses must be MRI compatible, up to 7 Tesla, and provide a range of optical corrections. The system must allow bi-directional communication and earphones must be using electrodynamic or electrostatic technology. They must be MRI compatible, up to 7 Tesla. The interfacing capabilities between the stimulation PC and the earphones are of primary importance. The device must not be software specific, i.e. any stimulation software able to send information. It must be specified how synchronization between the audio card and the earphone is achieved (what is the delay between the audio card and the stimulus delivery). The system must allow bi-directional communication and earphones must be using electrodynamic or electrostatic technology. An important factor to specify is the thickness, with a maximum of 26mm. Detail of the frequency range and responses is requested and will be taken into consideration. The interfacing capabilities between the stimulation PC and the earphones are also of importance. The device must not be software specific, i.e. any stimulation software able to send information. It must be specified how synchronization between the audio card and the earphone is achieved (what is the delay between the audio card and the stimulus delivery). Response devices must be MRI compatible up to 7 Tesla. The device must not be software specific, i.e. any software must be able to read information from the device. The amount of pressure to apply to trigger a response must be specified. The lot must be composed of 2 sets of: — The 1st set must include 2 devices with 1 or 2 buttons only. — The 2nd is composed of a single response device, which must have a least 4 buttons. The proposed device must interface easily with the scanner (electrical and optical input) and the PC use for stimulation (serial and USB). The video projector must have a shielding mechanism from the magnetic field up to 7 Tesla, have a resolution of at least 1920(H) by 1080(V) pixels and a frame rate of at least 60Hz for colour images. A screen to project the visual information must also be provided, the resolution of which shall be considered. The projector should be able to project through the waveguide (Projection horizontal screen size 60cm, Projection screen distance up to 474cm). The interfacing capabilities between the stimulation PC and the video projector are of primary importance. The device must not be software specific, i.e. any stimulation software able to send information. The capacity to interface with other (video or audio) devices other than the ones of the supplier shall also be considered. It must be specified how synchronization between the video card and the display is achieved (for instance, a buffer is used to achieve an exact timing on screen corresponding to N ms after the PC send the information).
