New SPECT/CT, PET/CT systems and a variety of gamma cameras are debuting at RSNA with new functionalities. Vendors promise more user friendliness, advanced algorithms, enhanced lesion detectability and quicker scan times.

Philips Medical Systems (Booth #7113) at RSNA 2004 will be launching a new PET/CT system. The company will also be highlighting its Precedence SPECT/CT system that provides physicians with tools to improve diagnostic confidence and patient care through combined SPECT and CT images. Philips will also be introducing its Molecular Imaging Suite. The software package provides tools to support key elements required for Molecular Imaging. The Suite may help expand the functional capabilities of SPECT and hybrid imaging systems through integrating Molecular Imaging applications into JETStream Workspace for improved workflow, productivity and ease of use, provide enhanced display tools and enable evaluation of individual SPECT and CT images. Philips also has on its roster of nuclear medicine products its JETStream Workspace, a comprehensive nuclear medicine workstation that encompasses all the imaging elements of a nuclear medicine department in one environment.

Siemens Medical Solutions (Booth #2729) is highlighting its TruePoint SPECT/CT, which debuted in June. The system, which combines Siemens' SPECT with its CT technology, can be used in the diagnosis and treatment of cancer, cardiac and neurological diseases. In cardiac applications, TruePoint SPECT/CT will provide information about cardiac function and overall health with its ability to measure attenuation correction with diagnostic multislice CT.

Toshiba America Medical Systems (Booth #7149) is highlighting its Signature series - an easy-to-use gamma camera for whole body, cardiac SPECT and general SPECT applications - that is available in three configurations: Variable, Cardio, and the Single. Features include: HD4 digital detectors, real-time automatic body contouring and advanced algorithms for diagnostic accuracy; patient comfort and entertainment system; 400-pound table capacity; e.soft and e.soft express, software for remote review of nuclear medicine, cardiac and PET cases; and data and images integrated with multiple vendors and modalities.

Hitachi Medical Systems America (Booth #8350) is rolling out its Sceptre P3 PET/CT hybrid imaging system. The system combines three technologies in one: Lutetium oxyorthosilicate (LSO) PET technology, Hitachi's fast quad-slice CT and connectivity to AVIA PACS. The system features dual attenuation correction (DAC Technology) and FDA approved Non-Rigid Fusion7D algorithm that provides precise registration by correcting for respiration differences between PET and CT acquisitions.

Pico 3-D electronics significantly improves count rate performance, energy resolution and scatter rejection resulting in enhanced lesion detectability and image quality improvements with large patients, Hitachi said.

The Sceptre P3 is designed with a field upgrade capability and allows Sceptre dedicated PET customers an opportunity to cost-effectively upgrade to the benefits of PET/CT.  The "Evolve" upgrade program is available to all Sceptre dedicated PET scanners including both installed and forward production systems.

Gamma Medica Inc. (Booth #1850) is showing off X-O, a new micro CT system and the newest addition to its line of pre-clinical imaging products. The system can perform full body scans on a wide range of test subjects in less than one minute. It also features a large field of view at nearly 1,000 cubic centimeters.

In addition, X-O is compatible with the company's other pre-clinical offerings, so users can upgrade by adding the company's SPECT components to their existing X-O Micro CT systems, and thus perform co-registered dual modality CT/SPECT imaging, Gamma Medica said.

CTI Molecular Imaging (Booth #1965) is bringing to the show PETConnect, a fully integrated range of web-delivered software tools and workstations for image analysis, education and practice management. Created in partnership between CTI Mirada Solutions and CTI PETNET, the technology provides all the functionality required to be a PET provider in either the entrepreneurial or hospital setting with specific focus on referral physician services, diagnostic tools and market education. Features include: Scenium, for detailed analysis of FDG uptake in patients with suspected Alzheimer's disease; Ostiview,
