“…A major portion of instrument development since then has consequently been directed at improvement of resolution (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). Figure 1 gives a measure of the success of this effort, showing that the intrinsic resolution of the 25-cm field-of-view, Anger-type camera has been improved by a factor of about 3 since it was first marketed in the U.S. 13-15 years ago.…”

The performance of present-day gamma-cameras is examined from a historical perspective and the prospects for further improvements assessed. The author attempts to show quantitatively that spatial resolution of 25-cm field-of view cameras has reached a point where further advances can bring only diminishing returns clinically, unless improvements in sensitivity, or alternatively, in photon yield of the clinical procedure, are also realized. However, better image contrast due to developments in display technology and emission computed tomography may improve lesion detectability more directly than would an increase in resolution.

“…The upper limit represents an average worst-case performance among the major manufacturers. (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). Dates plotted are those of publication, unless there was a specific date given for the measurement, which may result in a slight ('""-'1 yr) shift of the curve to the right.…”
