摘要: A gamma camera system includes a rotatable gantry supporting multiple detector heads each capable of receiving radiation from region interest subject disposed in an examination region. Each the include collimator which substantially defines resolution and sensitivity respective head. At least two collimators providing different resolution. Preferably, one provides head with high another sensitivity. An operator selectively combines image data detected by heads. If desired, combine variety manners to obtain images various single imaging procedure. The may also weight contribution that has overall image. As yet option, choose only energy portion so as minimize amount scatter events are included final
