Time-Coded Aperture Tomography: Experimental Results

In this paper, we discuss the applicability of a time-coded aperture system¿especially designed for thyroid tomography¿on the basis of phantom experiments. Our studies show that 1) the quality of the reconstructions is high (e.g., a cold spot of 6 mm diameter in a thyroid phantom can easily be detected), and 2) the reconstruction can be carried out in less than 11 min on a standard 16 bit minicomputer (HP1000). It is therefore concluded that the clinical potentiality of the device is good.
