Paper Abstract
In limited angular aperture tomosynthesis systems, the addition of new degrees of freedom for data
acquisition, such as angular aperture and sampling, requires specific optimizations. Typical optimization
criteria include MTF, SNR, and NEQ. However, the strong anisotropy of the sampling frequency on the zaxis
is usually neglected. Considering the signal in slices as the information contained within the volume
defined by the slice plane and the z-sampling interval, the MTF of the reconstruction is obtained by
integrating reconstruction blur within the slice. The relationship between z-sampling and aperture is
proposed in terms of preservation of the DQE.
