A gamma imaging device and an imaging method. The gamma imaging device comprises a detector; the detector comprises a single crystal strip (101); the single crystal strip (101) is used for moving relative to an imaging field of view to detect incident gamma photons of the imaging field of view, and realize collimation of the incident gamma photons, so as to realize gamma imaging, wherein the aspect ratio of the single crystal strip is greater than 10:1. A front end face (110) is an end face of the end of the single crystal strip (101) close to a radioactive source, a distal end face (120) is an end face of the end of the single crystal strip (101) farther away from the radioactive source than the front end face (110), and a front end and a distal end respectively form the two ends of the single crystal strip (101). L'invention concerne un dispositif d'imagerie gamma et un procédé d'imagerie. Le dispositif d'imagerie gamma comprend un détecteur ; le détecteur comprend une bande monocristalline (101) ; la bande
