Table II.

Comparison of TAC scale with and without attenuation and scatter corrections on microPET P4. Data in this table were calculated as follows: effect of attenuation on the TAC for Rat 1 in dual mode (−63.2%) is based on the percentage change from the attenuation corrected TAC (open triangles) to the uncorrected TAC (open circles) in Fig. 9(b). The effect of scatter on the TAC for Rat 1 in dual mode (12.2%) is based on the percentage change from the attenuation corrected TAC (open triangles) to the attenuation and scatter corrected TAC (filled diamonds) in Fig. 9(b). Both scatter and attenuation effects are relative to the uncorrected curve (open triangles).

	Effect of Scatter on scale (%)	Effect of Attenuation on scale (%)
Rat 1 Dual	12.2	−63.2
Rat 2 Dual	12.4	−61.0
Rat 1 Single	5.4	−57.4
Rat 2 Single	6.9	−56.6
