X-ray phase contrast imaging method is able to show microstructure inside soft tissues with weak absorption in a radiograph mode. X-ray phase contrast CT is being under study. We propose a multi-criterion optimization approach to reconstruct the object from phase contrast images. Our reconstructed results show that the method can differentiate boundary of microstructure of fly very clearly. Comparison...
For appropriate diagnosis, medical image such as high quality image of patient's affected part and vital signal, patient information, and teleconferencing data for communication between specialists will be transmitted. After connecting patient and specialist the center, sender acquires patient data and transmits to the center through TCP/IP protocol. Data that is transmitted to center is retransmitted...
The research on digital visible human is of great significance and application value. The US Visible Human Project (VHP) created the first digital image data set of a complete human (one male and one female) in 1995. To promote a worldwide application-oriented VHR, more visible human data sets representative of different populations of the world are in demand. The Chinese Visible Human (CVH) male...
Computed tomography angiography (CTA) is an established tool for vascular imaging. However, high-intense structures in the contrast image can seriously hamper luminal visualisation. This can be solved by subtraction CTA, where a native image is subtracted from the contrast image. However, patient and organ motion limit the application of this technique. Within this paper, a fully automated intensity-based...
Computer-assisted surgery is the process of using medical images, such as CT scans, X-ray fluoroscopy, or 3D ultrasound, to improve patient care. A typical surgical procedure begins by acquiring and processing a CT scan with specially developed image-analysis software. A surgeon then performs a "virtual surgery" on the patient to develop a preoperative plan. In the operating room the medical...
Imaging looks inside the patient's body, exposing the patient's anatomy beyond what is visible on the surface. Medical imaging has a very successful history for medical diagnosis. It also plays an increasingly important role as enabling technology for minimally invasive procedures. Interventional procedures (e.g. catheter based cardiac interventions) are traditionally supported by intra-procedure...
