The 11th International Conference on Image and Graphics (ICIG) will be held in Haikou, China, on 26 – 28, November, 2021. We sincerely invite the researches over the world in this area to join us.
ICIG 2021 Symposium：Medical Imaging Computing: From Theory to Applications
Medical Image Computing (MIC) pioneers research in machine learning and information processing, with the particular aim of improving patient care by systematic image data analytics. Many works have been developed to structure and quantify imaging information from multiple time-points and imaging technologies, e.g. magnetic resonance imaging or computer tomography, and link it with clinical and biological parameters. As an initiator and co-coordinator of China Society of Image and Graphics, we organize this symposium to review the developments at the core of computer science, with applications in but also beyond medicine.
Automatic diagnosis of cardiovascular interventional image
With the accelerating aging of the population in China, the prevalence and mortality of cardiovascular diseases have increased significantly. Cardiovascular disease is the leading cause of death among urban and rural residents, which is higher than other diseases such as tumors and respiratory systems. Traditional cardiovascular images diagnosis mainly relies on manual subjective analysis, which requires a lot of time and cost. At the same time, due to the influence of factors like intravascular ultrasound imaging mechanism and equipment, the generated image has a unique speckle noise, which seriously affects the image quality. At present, intravascular ultrasound (IVUS) and optical coherence tomography (OCT) are the two main imaging methods used in medical practice. Therefore, we mainly focused on IVUS and OCT images to study the denoising algorithm of cardiovascular images to obtain clear images. Secondly, we use deep learning methods to segment the vascular membrane structure, stents, plaques, etc., and finally study the blood vessel three-dimensional visualization. The research results can not only assist doctors in diagnosis and treatment, but also improve doctors' work efficiency and detection accuracy. Besides, this research can deepen researchers' understanding of the mechanism of cardiovascular disease and provide more feasibility for the research and development of cardiovascular disease.

Unsupervised deep learning based denoising for PET image
Positron emission tomography (PET) is a powerful imaging method in nuclear medicine that can detect the metabolic activity of molecules in living tissues. PET image generally has the problem of low signal-to-noise ratio, which will influence the accuracy of diagnosis. Recently, deep learning has been widely used in the field of medical imaging denoising but usually, deep learning denoising methods need the use of low-quality/high-quality image pairs to supervise the network training. However, in real clinical practice, it is difficult to obtain high-quality PET images for training. Therefore, we proposed an unsupervised deep learning denoising framework, Conditional Deep Image Prior, for PET image denoising. Our experiments showed that based on this framework, excellent denoising effects can be achieved only using the noisy PET image and the registered CT/MR image.

Computational Diffusion MRI and Its Applications in Schizophrenia
White matter tracts consisting of axons that connect distinct brain regions are important for brain functions. Diffusion MRI (dMRI), together with computational tractography, provide non-invasive methods to reveal the microstructure of the white matter of the in-vivo human brain. The first part of this talk will provide a brief methodological overview of dMRI analysis and tractography. DiffusionKit, a light, one-stop, cross-platform solution for dMRI data analysis, will be presented. Multiple lines of evidence indicate that the microstructure of white matter tracts is implicated in the pathophysiology of schizophrenia. In the part of applications in schizophrenia, we investigated the language pathways in schizophrenia patients with auditory verbal hallucination (AVH). Reproducible abnormal pattern of arcuate fasciculus in schizophrenia with AVH base on multi-site diffusion MRI data were found. Besides, we explored the 25 major white matter tracts with dMRI-based tractography in schizophrenia patients and their unaffected first-degree relatives to investigate disease-related and/or genetic risk-related anatomical variations in schizophrenia. Our results suggest that alterations in the left superior longitudinal fasciculus and anterior thalamic radiation are features of established illness, which may serve as neural substrates for the psychopathology of schizophrenia.

Artificial Intelligence in Cardiac Image Analysis
According to World Health Organization, cardiac disease has been the major reason leading to the mortality in all causes. The Report on Cardiovascular Disease in China shows that the number of patients with cardiac disease in China has reached 330 million. The artificial intelligence has shown the benefit to the medical intervention, and gradually indicated its effectiveness by combining with the cardiac medical image. This talk introduces recent studies proposed by our research group in the medical image analysis and artificial intelligence for cardiac disease. It focuses on two aspects, the morphological abnormality and the functional abnormality, and then introduce several cardiac image analysis tasks in various image modalities. This talk further explains how these studies can decrease the labor consumption, improve efficiency, and reduce costs and risks during the diagnosis and treatment.
