FIGURE 2. The extrinsic resolution (Resolution) vs. source depth for a standard ${gamma}$ -camera (STD Gamma Cam) with 3.5-mm intrinsic resolution and a dedicated breast camera (LumaGEM) with 2-mm intrinsic resolution. The solid line represents extrinsic resolution vs. source depth when detector resolution is equal to collimator resolution (Coll Res = Det). The points representing the standard ${gamma}$ -camera ( ${circ}$ ) and the dedicated breast camera ( ${triangleup}$ ) are shown.
