A Bayesian Optimization Approach for Attenuation Correction in SPECT Brain Imaging

  title={A Bayesian Optimization Approach for Attenuation Correction in SPECT Brain Imaging},
  author={Loizos Koutsantonis and A.Z. Makki and Tiago Carneiro and Emmanuel Kieffer and Pascal Bouvry},
Photon attenuation and scatter are the two main physical factors affecting the diagnostic quality of SPECT in its applications in brain imaging. In this work, we present a novel Bayesian Optimization approach for Attenuation Correction (BOAC) in SPECT brain imaging. BOAC utilizes a prior model parametrizing the head geometry and exploits High Performance Computing (HPC) to reconstruct attenuation corrected images without requiring prior anatomical information from complementary CT scans. BOAC… Expand

SPECT-CT in routine clinical practice: increase in patient radiation dose compared with SPECT alone
Assessment of the patient radiation dose during routine clinical single-photon emission computed tomography-computed tomography (SPECT-CT) and measure the increase as compared with SPECT alone concluded that appropriate utilization and optimization of the protocols of SPECT- CT is needed to maximize benefit to patients.

Impact of CT based attenuation correction on quantitative assessment of DaTSCAN ((123)I-Ioflupane) imaging in diagnosis of extrapyramidal diseases.
The quality of DaTSCAN images reconstructed with the use of ordered-subset expectation maximization reconstruction technique (OSEM) with attenuation Correction based on CT maps was found to be superior to that provided by the commonly applied filtered backprojection method (FBP) with Chang attenuation correction.

Image quality assessment: from error visibility to structural similarity
A structural similarity index is developed and its promise is demonstrated through a set of intuitive examples, as well as comparison to both subjective ratings and state-of-the-art objective methods on a database of images compressed with JPEG and JPEG2000. Expand
Inversion of the attenuated Radon transform
We derive an exact inversion formula for the attenuated Radon transform. The formula is closely related to Novikov's inversion formula, but our derivation is completely different. We also give anExpand
