Abstract
1339330 Scintillation camera NUCLEARCHICAGO CORP 26 Oct 1971 [27 Oct 1970] 49595/71 Heading H4F To improve the resolution of a scintillation camera, e.g. an Anger camera 40, Fig. 5, a radiation filter 20 having a plurality of spaced apertures is mounted between the radioactive object 10 and cameras detector head, and an optical filter 70 having a similar array of apertures but of smaller dimension than the apertures in filter 20 is mounted between the CRT display screen 61 of the Anger camera's output and a photographic camera 80, and the two filters 20 and 70 are synchronously scanned, e.g. as shown in Fig. 7b, where 211, 212 &c. comprises the apertures in filter 20 and 711, 712 &c. the apertures in filter 70. Instead of using an optical filter 70 an electrical analogue thereof may be included in the detective electronics 50 (Fig. 6, not shown). Filter 20 may constitute the conventional multichannel collimator or such collimator 30 may be included as shown. The size and separation distance of the apertures in the filters are preselected in terms of the full width at half maximum resolution value of the camera to produce a desired improvement in resolution (Fig. 3c, not shown).
