“…Biplane XMRF registration was made possible with further development of the prototype, and the need for C-arm dry spin was obviated. 3D/3D registration could be performed with both contour and surface carving were supported, allowing clear presentation of complex 3D structures [16]. This was performed in 20 patients, using surface models generated by threshold-based segmentation from high resolution magnetic resonance angiogram of structures of interest.…”

KEYWORDS• congenital cardiology • image fusion • image registration • medical image computing Image fusion: definition Image fusion consists of registering and visualizing different sets of images of a given object or scene. In medical disorders, pathology affects different tissues in a variable manner. These are best imaged in different modalities using diverse technologies. Image fusion helps to integrate all of the information and aids in accurate diagnosis and treatment. The implicit image fusion composed by the treating physician can be subjective and prone to error, which image fusion systems can help to mitigate. Medical image fusion is a very broad field covering aspects of computer vision, pattern recognition, machine learning and artificial intelligence in addition to image processing. Brief historyThe earliest mention of the word 'image fusion' in the clinical context was in 1992 by Swayne, who reported on computer-assisted fusion of single-photon emission computed tomographic (SPECT) and computed tomographic (CT) images in localizing inflammatory processes in 10 patients [1]. A combination of standard scaling, rotation, translation and stretching transformations were used to fuse images with anatomic and external landmarks. Stereotactic neurosurgery [2] was the next major application for image fusion, closely followed by oncology [3]. Rapid improvements in computers and their processing power led to increasing development and use of image fusion, particularly in imageguided surgery in a variety of medical specialties. The problems with software-based posthoc image fusion have led to the development of combined scanners, which acquire both anatomical and functional images during a single imaging session. This is achieved by fusing of technologies such as PET/CT scanner and PET/MRI scanner [4]. This also stimulated the development of co-location of complementary imaging modalities such

Because of the complex and fine structure, visualization of the heart still remains a challenging task, which makes it an active research topic. In this paper, we present a visualization system for medical data, which takes advantage of the recent graphics processing unit (GPU) and can provide real-time cardiac visualization. This work focuses on investigating the anatomical structure visualization of the human heart, which is fundamental to the cardiac visualization, medical training and diagnosis assistance. Several state-of-the-art cardiac visualization methods are integrated into the proposed system and a task specified visualization method is proposed. In addition, auxiliary tools are provided to generate user specified visualization results. The contributions of our work lie in two-fold: for doctors and medical staff, the system can provide task specified visualization with interactive visualization tools; for researchers, the proposed platform can serve as a baseline for comparing different rendering methods and can easily incorporate new rendering methods. Experimental results show that the proposed system can provide favorable cardiac visualization results in terms of both effectiveness and efficiency.
