The dose received by a patient on CT examination is expressed in size-specific dose estimates (SSDE) which is a function of the patient diameter, x-ray attenuation, and scanner output (volume computed tomography dose index, CTDIvol). Patient diameter and

SSDE: Fast Graph Drawing Using Sampled Spectral Distance Embedding [PDF]
We present a fast spectral graph drawing algorithm for drawing undirected connected graphs. ClassicalMulti-Dimensional Scaling yields a quadratic-time spectral algorithm, which approximates the real distances of the nodes in the final drawing with their graph theoretical distances.

Effects of various tilt angles on radiation dose and image quality in pediatric head computed tomography: A phantom study. [PDF]
Abstract Background Various methods have been employed to reduce radiation dose and improve image quality in head computed tomography (CT); however, the impact of different head tilt angles on these factors remains underexplored. Objective To investigate the effects of different head tilt angles on radiation dose and image quality in head CT. Materials

Self-Adapting Spherical Search Algorithm with Differential Evolution for Global Optimization
The spherical search algorithm is an effective optimizer to solve bound-constrained non-linear global optimization problems. Nevertheless, it may fall into the local optima when handling combination optimization problems.

Institutional CT dose reduction: A retrospective evaluation of dose indices from 2015–2024 [PDF]
Abstract Background Growing attention to radiation risks and dose reduction in CT imaging creates opportunities to present and discuss institutional dose trends and contributing factors. Purpose To provide an evaluation of 10‐year trends in CT dose indices (CTDIvol and DLP) from a multi‐site and multi‐scanner institution, with the hypothesis that doses

Sjögren’s syndrome dry eye (SSDE) is a subset of Sjögren’s syndrome marked by dry eye symptoms that is distinct from non-Sjögren’s syndrome dry eye (NSSDE). As SSDE can lead to severe complications, its early detection is imperative.

SSDE-Cluster: Fast Overlapping Clustering of Networks Using Sampled Spectral Distance Embedding and GMMs [PDF]
Clustering social networks is vital to understanding online interactions and influence. This task becomes more difficult when communities overlap, and when the social networks become extremely large. We present an efficient algorithm for constructing overlapping clusters, (approximately linear).
