| 3 Tesla MRI Scanners |
The HIC houses two whole body 3T MRI scanners fully dedicated to research studies, the Philip 3TX Elition with a 70 cm bore and the Philips 3T Ingenia CX with a 60 cm bore. Both scanners have 2 channel RF transmit capability for imaging and an array of receive RF coils for imaging the head, torso, and the extremities. Both 3T systems have Philips peripheral pulse, respiratory and cardiac gating capabilities as well as a complete suite of audio/visual presentation equipment and software for functional MRI studies. The scanners operate on the state-of-the art Philips software platform with capabilities like compressed sensing, simultaneous multislice imaging, multinuclear imaging, MR spectroscopy, realtime motion monitoring (FIRMM) and Philips dStream technology.

| 7 Tesla MRI Scanner |
The HIC houses a whole body 7 Tesla MRI scanner with a 90 cm bore for ultra-high resolution, high SNR imaging. The 7T scanner is equipped with state-of-the-art 8 channel RF transmit and multichannel channel receive capability for head imaging. Spinal cord imaging is offered with a dedicated 16 channel spine coil. The system software offers the latest imaging capabilities like compressed sensing, simultaneous multislice imaging, multinuclear imaging, MR spectroscopy, realtime motion monitoring (FIRMM), all with Philips dStream technology. The system has peripheral pulse, respiratory and cardiac gating capabilities and a complete suite of audio/visual presentation equipment for functional MRI studies.

| Mock Scanner |
This laboratory consists of an inactive scanner identical to that of our research systems, and includes an audio system for playing reproductions of scanner noises. This laboratory is designed to introduce patients, particularly children, to the environment in the actual scanner, and to screen for claustrophobia.

| Optical Coherence Tomography |
SPECTRALIS OCT is a non-invasive ophthalmic multimodality imaging instrument which uses near-infrared light to visualize and measure the thickness of retinal layers. Real time tracking of the retinal structures can be used to detect early signs of eye conditions, diabetes, and coronary events. Click here for a video!

| Dual Energy X-ray Absorptiometry (DXA) |
The Hologic Horizon series W scanner incorporates 128 multi-channel detectors (2mm) consisting of CdWO4 scintillators coupled to silicon diodes, an indexing table, and motorized C-arm. The x-ray tube operates with a fan beam and a single pass acquisition with switching pulsating dual-energy x-rays. It operates at 100kV and 140kV, 2.5mA average at 25% duty cycle, 5.0mA average at 50% duty cycle (30s maximum) with a tungsten target to obtain high quality and high precision analyses for bone density and total body DXA scans.

| Positron Emission Tomography and Computerized Tomography |
94 cm bore Philips Intera Achieva MR whole-body imager/spectrometers. Both represent state-of-the-art systems with excellent gradient performance (80 mT/m gradient strength, 200T/m/s slew-rate), 32 independent digital receiver channels, dual-channel excitation (one of the two systems). The 3 T scanners are operated as full-time research instruments, and not as clinical facilities. Both 3 T systems have Philips peripheral pulse, respiratory and cardiac gating capabilities as well as audio/visual presentation equipment available.
