Computed Tomography

7.6K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies for Cardiovascular System V: CT

673
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

    • To explore the generation of synthetic cardiac Computed Tomography Angiography (CTA) images using fine-tuned Stable Diffusion models.
    • To address the challenge of limited data availability in cardiovascular imaging research.

    Main Methods:

    • Fine-tuning Stable Diffusion models with a limited dataset of cardiac CTA images.
    • Utilizing user-defined text prompts for image generation.
    • Conducting comprehensive evaluations including quantitative analysis and qualitative assessment by a clinician.

    Main Results:

    • Successful generation of synthetic cardiac CTA images using a Text-to-Image (T2I) Stable Diffusion model.
    • The optimized T2I CTA diffusion model effectively rendered images with features characteristic of acute type B aortic dissection (TBAD).

    Conclusions:

    • Text-to-Image Stable Diffusion models are capable of generating realistic cardiac CTA images.
    • This approach can help overcome data scarcity issues in cardiovascular imaging, enhancing ML algorithm development for conditions like TBAD.
