Current standard clinical SPECT techniques provide a resolution of at best 1 cm and sensitivity in the order of 10. Performance is largely determined by the collimator. Basic geometry couples resolution and sensitivity; the problem of high-resolution imaging is a formidable one because, to image at constant Signal-to-Noise, resolution improvements must be supported by simultaneous sensitivity improvements that scale with the fourth power of resolution. However, current standard systems are… CONTINUE READING
