摘要:
Using a procedure enabling the assessment of background radiation research was done to elucidate the course of changes in background activity during gastric emptying measurement. Attention was focused on the changes in the shape of power-exponential fitted gastric emptying curves after correction for background was performed. The observed pattern of background counts allowed to explain the shifts of the parameters characterizing power-exponential curves connected with background correction. It was concluded that background had a negligible effect on the power-exponential fitting of gastric emptying curves.
