	conventional pulse sequences such as Spin Echo, Field Echo and Inversion Recovery.
	Fast scan sequences such as FastSE, FastIR, FastFLAIR, FastSTIR and FastFE.
	FastASE -RF Refocused EPI FastASE is an advanced FastSE based sequence with a large number of echoes (maximum 213 ETL) which is combined with Half Fourier Imaging to reduce scan times dramatically by a factor of 384. A single TR is enough to generate multiple images in a few seconds. Available with both 2DFT and 3DFT, FastSE provides T2 weighted images and is an RF refocused EPI technique. FastASE could potentially broaden MR applications enabling MRCP (MR Cholangiopancreatography), Urography and Myelography.
	QuadScan Advanced digital RF capabilities provide precise phase control. This permits simultaneous excitations of four slices while minimizing excitations of four slices while minimizing RF power requirements with Toshiba’s QuadScan technique. QuadScan offers either twice the SNR or four times the coverage for both SE and FE sequences.
	MR Fluoroscopy Images are continuously acquired and reconstructed then displayed in virtually real time. Slice orientation, slice position, acquisition data read—out direction, slice thickness, FOV, NAQ, TR and Flip angle may be varied interactively while scanning
	Real Time Locator An advanced application of MR fluoroscopy which acquires axial, coronal and sagittal planes. Fast reconstruction and display of the data in real-time facilitates patient positioning.
	Vascular Imaging Techniques Fine vascular structures are visualized with various innovative techniques such as 2D & 3D Time of flight and 2D & 3D Phase shift. Slice Selective off Resonance Sync Pulse (SORS—STC) and Inclined slab for Contrast Enhancement (ISCE) are available with 3D—TOF for reduced background signal and greater image quality. Maximum Intensity Projection can be performed while acquiring subsequent scans for greater productivity.
	Advanced Fat Suppression Techniques Various sequences are provided for uniform, fat suppression over an imaging area. Sequences include: IR, STIR, FastIR and FastSTIR.

	A 23” monitor and 1280x3024 display matrix for high resolution display.
	Extended keyboard and mouse.

OPART’s RISC platform provides an Icon-based X-window user interface which allows for simple and fast system operations. The true multi-tasking system facilitates patient registration, scan planning, image review and filming for maximum efficiency and productivity.

	Integrated workstation capabilities eliminate the need to purchase a separate viewing console.
	User interface eliminates keyboard entry of commands.
	Calendar — is an easy to use advanced patient scheduling and registration tool.
	Memory — OPART protocols may be preprogrammed and accessed by a simple click of the mouse over an anatomical icon. An integrated smart system, the software eliminates guesswork and conducts a real-time “what if” exchange to optimize sequence parameters.
	Graphic scan planning — easy to understand graphics and prompts to quickly plan subsequent exams and input last minute “sequence parameter selections.
	Image selector— displays visual “table of contents” for quick and simple image display of complete studies.
	Batch MIP and CINE display while continuing other functions.
	Extensive post processing algorithms for image enhancement.

Cryogenless Superconducting O.35T Open Magnet

OPART‘s four-sided Open design is both self-shielded and cryogenless thereby eliminating the need for routine cryogen refills:

	High homogeneity magnet maximizes the image quality for the broad patient population.
	Homogeneity is optimized with a passive shimming system. This stable method does not require regular maintenance.

Ergonomically designed to maximize patient comfort and accommodate a diverse patient population, the couch features lateral table-top movement to simplify patient positioning to magnet iso-center.

	Accommodates patients up to 500 pounds.
	Horizontal movement ±10cm left and right from magnet center.

	A RISC based computer platform and independent real-time manager (RTM) delivers true multi-tasking with speed and flexibility. MIP processing of angio images and CINE display do not require optional memory or array processors.
	64-bit RISC processor with 256MB memory and UNIX operating system.
	4GB Hard disk memory for 20,000 image storage (256x256).
	Instantaneous (<0.5 sec) reconstruction per image.

For OlE Systems from R143 on up

The Performance Plus Option improves the gradient performance of OPART in addition to providing two advanced pulse sequences:

	Water—Fat Separation
	Echo Mapping

The Advanced Gradient Compensation Control improves the gradient control and increases their precision. This improvement allows the use of the two advanced pulse sequences included in this option as well as possible future advanced pulse sequences.

The Water—Fat separation advanced pulse sequence uses a 3 point Dixon method to produce two sets of images: one predominantly Water and the other predominantly Fat. This imaging technique can be used in imaging joints and breast as well as other anatomy.

Echo Mapping increases slice coverage and reduces scan time up to 40% over conventional Fast Spin Echo. This is accomplished by combining half Fourier imaging, echo sharing and advanced post processing. This sequenced can be used in the brain, spine and knee where a large number of slices are required.
