[en] Aim: Anger cameras are still useful in a number of routine Nuclear Medicine procedures. Nevertheless the analog images and old computer systems usually associated with these systems, have serious limitations compared with modern machines. Here we present the result of a combined hardware/software approach to digitalize and optimize the existing equipment to obtain better image/data quality. Material and Methods: The digitalization system was created with PCs (Olidata Alicon 2 Multimedia PC) connected to three Anger cameras (Picker Dyna Camera 4/15, Ohio-Nuclear Sigma 410, and Technicare 438 HR) using Slovenian acquisition boards (GAMMA-PF, version 97.3-5-7/7). The PCs are connected to a PC Server (Compaq Proliant 800) using an Ethernet LAN in such a manner that the images obtained through the gamma cameras and digitized by the GAMMA-PF acquisition boards, are finally saved locally and in the Server. The digitalization system (acquisition board/associated software) handles the data corrections (energy, linearity, uniformity), real time events acquisition and storage (in the local and remote hard drive). A Nuclear Medicine image processing software (named GISP) was developed using IDL (data visualization and programming tool; Research Systems Inc.). This software provides the necessary functions to handle static and dynamic images display, image quantification: ROI's, time/activity curves, profiles, background substraction and some predefined protocols (static and dynamic renal studies, esophageal motility and reflux, etc.). This software uses the hardcopy device (Matrix Instruments Video Imager) attached to an existing SPECT system, generating an 'snapshot' image (in its native format) which is added to the patients database at the SPECT's workstation, to print the exam images. A second image in JPEG format is generated at the same time, which is published in a Web site along with the nuclear medicine physician report, for later or remote retrieval and visualization. Results: This system developed with the latest computer technology, allows to obtain better quality images than with the analog one (in computer screen and film). Besides, this system improves image processing flexibility. GISP software, and the complete hardware/software system, were tested with different types of phantoms getting numerical and graphic curves that it is between generally accepted intervals. With this new digital system, the use of film and chemicals per exam decrease: film 24.6%, and chemicals 35.7%. Conclusion: The images digitized using the system here described, and processed using GISP software, allows to get better quality visualized and printed exam images in a more flexible and economic way
