Proton computed tomography (CT) has been demonstrated as a promising image modality in particle therapy planning. It can reduce errors in particle range calculations and consequently improve dose calculations. Obtaining a high imaging resolution has traditionally required computationally expensive iterative reconstruction techniques to account for the multiple scattering of the protons. Recently, techniques for direct reconstruction have been developed, but these require a higher imaging dose…

An optimization algorithm for dose reduction with fluence-modulated proton CT.

Application of fluence field modulation to proton computed tomography for proton therapy imaging

FMpCT is shown to be potentially feasible and may allow a means of imaging dose reduction for a pCT scanner operating in PB scanning mode, and may be of particular importance to proton therapy given the low integral dose found outside the target.

Sinogram interpolation method for limited-angle tomography

This work proposes a new algorithm using the sinogram interpolation to reconstruct the image from insufficent number of projections of X-ray tomography and shows improved quality of CT images with reduced artifacts in the reconstruction results.

A comparison of direct reconstruction algorithms in proton computed tomography

A comparison between five algorithms proposed to take into account the non-linear path of protons in the reconstruction of a proton CT (pCT) image, in terms of spatial resolution and relative stopping power (RSP) accuracy.

Experimental realization of dynamic fluence field optimization for proton computed tomography

It is concluded that FMpCT optimized for specific image noise prescriptions is experimentally feasible and a correction method is proposed that removes image artifacts stemming from the acquisition with pencil beams having a spatially varying energy distribution that is not seen in clinical operation.

Filtered backprojection proton CT reconstruction along most likely paths.

Improved spatial resolution was obtained in pCT images with filtered backprojection reconstruction using most likely path estimates of protons, which makes this new algorithm a candidate of choice for clinical pCT.

Proton computed tomography reconstruction using a backprojection-then-filtering approach

The BPF algorithm requires only one backprojection and filtering operation on a scan data set, it also offers computational advantages over an iterative reconstruction approach and the superior spatial-resolution of the BPF method over the standard filtering-then-backprojection approach is demonstrated.

Modern prototypes of proton computed tomography (CT) scanners can measure the energy, the position and the direction of each proton, before and after the scanned object, in a list mode. Each detected

Combining Ordered Subsets and Momentum for Accelerated X-Ray CT Image Reconstruction

If the number of subsets is too large, the OS-SQS-momentum methods can be unstable, so this paper proposes diminishing step sizes that stabilize the method while preserving the very fast convergence behavior.
