Conditional t-SNE: Complementary t-SNE embeddings through factoring out prior information [PDF]
Dimensionality reduction and manifold learning methods such as t-Distributed Stochastic Neighbor Embedding (t-SNE) are routinely used to map high-dimensional data into a 2-dimensional space to visualize and explore the data.

Synthetic CT generation from CBCT images via deep learning
PurposeCone‐beam computed tomography (CBCT) scanning is used daily or weekly (i.e., on‐treatment CBCT) for accurate patient setup in image‐guided radiotherapy. However, inaccuracy of CT numbers prevents CBCT from performing advanced tasks such as dose calculation and treatment planning. Motivated by the promising performance of deep learning in medical

A Novel Synthetic CT Generation Method Using Multitask Maximum Entropy Clustering
Due to the risk of radiation from computed tomography (CT) scanning on the human body, the number of CT scans that can be performed on an individual each year is limited. However, CT images play a very important role in medical diagnosis. Therefore, this

Patient-specific stopping power calibration for proton therapy planning based on single-detector proton radiography. [PDF]
A simple robust optimizer has been developed that can produce patient-specific calibration curves to convert x-ray computed tomography (CT) numbers to relative stopping powers (HU-RSPs) for proton therapy treatment planning.

Advances in generating sCT images from brain MR images based on deep learning
Radiotherapy is a crucial modality in the treatment of malignant tumors. Precision radiotherapy planning typically requires the integration of computed tomography (CT) and magnetic resonance imaging (MRI).

Synthetic CT in Musculoskeletal Disorders
AbstractRepeated computed tomography (CT) examinations increase patients' ionizing radiation exposure and health costs, making an alternative method desirable. Cortical and trabecular bone, however, have short T2 relaxation times, causing low signal intensity on conventional magnetic resonance (MR) sequences.
