| Popis: | In an attempt to improve radioisotope scanning, we are currently exploring a simple, inexpensive means of improving scan interpretation by minifi-cation and improved Teledeltos dot scanning. These methods, along with some of our early experience, are presented below. A rectilinear scanner with a 5-in. crystal, utilizing photorecording and dot presentation, was modified as follows: Two pantographs were installed by attaching them to the printing arm (stylus) of the scanner, both moving simultaneously with the motion of the scanning arm (Fig. 1). Each pantograph is equipped with a connection to the scanner output and has its own stylus. It is thus possible to perform scans of varying sizes by making simple adjustments of the pantographs. The scans printed out by the pantograph styluses will have identical data, but will be printed in a relatively smaller, although geometrically similar area. This technic alone has some interpretative advantages. Seltzer (1) noted the advantages of minifying scans. The impro... |
