Automatic online quality control of synthetic CTs [PDF]

Medical Imaging 2020: Image Processing, 2020
Accurate MR-to-CT synthesis is a requirement for MR-only workflows in radiotherapy (RT) treatment planning. In recent years, deep learning-based approaches have shown impressive results in this field. However, to prevent downstream errors in RT treatment planning, it is important that deep learning models are only applied to data for which they are ...

Abdominopelvic MR to CT registration using a synthetic CT intermediate

Journal of Applied Clinical Medical Physics, 2022
AbstractAccurate coregistration of computed tomography (CT) and magnetic resonance (MR) imaging can provide clinically relevant and complementary information and can serve to facilitate multiple clinical tasks including surgical and radiation treatment planning, and generating a virtual Positron Emission Tomography (PET)/MR for the sites that do not ...

3D-printed saw guides for lower arm osteotomy, a comparison between a synthetic CT and CT-based workflow [PDF]

, 2021
BACKGROUND: Three-dimensional (3D)-printed saw guides are frequently used to optimize osteotomy results and are usually designed based on computed tomography (CT), despite the radiation burden, as radiation-less alternatives like magnetic resonance ...

Synthetic CT in Carbon Ion Radiotherapy of the Abdominal Site

Bioengineering, 2023
The generation of synthetic CT for carbon ion radiotherapy (CIRT) applications is challenging, since high accuracy is required in treatment planning and delivery, especially in an anatomical site as complex as the abdomen. Thirty-nine abdominal MRI-CT volume pairs were collected and a three-channel cGAN (accounting for air, bones, soft tissues) was ...

MRI‐based synthetic CT shows equivalence to conventional CT for the morphological assessment of the hip joint [PDF]

Journal of Orthopaedic Research, 2021
AbstractThis study evaluated the accuracy of synthetic computed tomography (sCT), as compared to CT, for the 3D assessment of the hip morphology. Thirty male patients with asymptomatic hips, referred for magnetic resonance (MR) imaging and CT, were included in this retrospective study.

TCGAN: a transformer-enhanced GAN for PET synthetic CT

Biomedical Optics Express, 2022
Multimodal medical images can be used in a multifaceted approach to resolve a wide range of medical diagnostic problems. However, these images are generally difficult to obtain due to various limitations, such as cost of capture and patient safety. Medical image synthesis is used in various tasks to obtain better results.
