Argus Gamma Camera
Single headed gamma camera, depending on it's date of manufacture may have an analogue detector or a digital EPIC detector. Earlier versions were equipped with a PegasysX processing system while later systems had an atlas acquisition system and Pegasys Ultra10 or Ultra60 processing system.
Forte Gamma Camera
Dual headed gamma camera with EPIC detectors. Automatic collimator exchanger. It was manufactured after the Vertex models and differs from them by having an open gantry design, i.e. a single ring that supports both heads compared to the Vertex and Genesys camera which are dual ring designs. This enabled the Forte detectors to achieve a positional flexibility that was not possible with Vertex and Genesys cameras. Has a variable geometry allowing the detectors to be positioned at 90 degrees or 180 degrees relative to each other. Supports Molecular Coincidence Detection (MCD) and attenuation correction in normal and MCD modes.
Genesys Gamma Camera
The Genesys gamma camera was the predecessor to the Vertex camera. A dual headed, dual ring design, equipped with either analogue or EPIC detectors. A smaller patient aperture than the Vertex camera but the same detector field of view. Does not support attenuation correction or Molecular Coincidence Detection.
Skylight Gamma Camera
This was the first gamma camera to adopt a ceiling mounted design. In fact calling it ceiling mounted is a little misleading. The detectors are in fact mounted in a frame that is supported at four corners by the floor. Hence when installing this camera no structural load checks need to be performed on the ceiling. The structural checks should be performed on the floor. The Skylight gamma camera is again equipped with updated EPIC detectors, these detectors differ from those fitted to the Vertex and Forte cameras by using different PMT's and having energy, linearity and flood corrections performed in the detectors on the 'ACE' pcb rather than on the 'MCE' pcb that is found in the atlas or PegasysX computer cabinets. Other improvements included enhanced positional flexibility of the detectors. A new Microsoft Windows based acquisition system written in JAVA. Automatic collimator with wall vertically mounted collimators to increase floor space and the ability to scan two patients simultaneously, using single detector protocols. Has a variable geometry allowing the detectors to be positioned at 90 degrees or 180 degrees relative to each other. As of May 2005 I do not believe it supports attenuation correction, nor does it support Molecular Coincidence Detection.
Transcam Gamma Camera
A single headed mobile gamma camera. Small field of view circular detector but optionally supplied with a converging collimator. Equipped with a DOS based acquisition system and the capability to transfer image data via interfile to a Pegasys processing workstation.
