REKONSTRUKSI 4D CITRA MRI ALIRAN DARAH DAN TROMBUS PADA PASIEN ANEURISMA AORTA ABDOMINALIS

Abdominal aortic aneurysm (AAA) is the most common location of an aneurysm in the blood vessel diseases. Therapeutic indications for AAA non-rupture is mainly based on the criteria of maximum diameter of the aneurysm. Commonly accepted therapeutic indication is when the largest diameter reaches 5.5 cm. In fact, some small aneurysms (less than 5.5 cm) can rupture, while the bigger may not. In addition, there are other variability that have big influence in the evolution of diameter on small AAA was observed, such as the presence of thrombus in the AAA, the velocity profile of blood flow, and the blood volume inside the AAA. Image processing is a job out of range for a doctor. Thus, improve the living material modeling techniques and simplifies the material biomechanical that still a matter of discussion, will create new opportunities for the application of Information Technology in medical area. Deformable models approach for image segmentation of dynamic blood flow has been used and developed in conjunction with the method of scalar volume data (isosurface) to produce image reconstruction which can represent the anatomy of the aortic aneurysm with blood flow animation in each category of thrombus. This method has been proven to successfully presenting the animation of blood flow based on distinction the color of vector that adapted to the direction of blood flow in each coordinate axis (x, y, z). White color which has the highest intensity value has been successfully visualized as a color that represents the presence of thrombus in the aneurysm. The results of this research can be used by relevant experts in the field of Cardiovascular whose using MRI for observations, as well as helping the aortic surgeon in the decision to perform surgery before the rupture of the aortic wall that causes death. The result of this research is a software that can categorize thrombus in the small AAA. This software also can extract and reconstruct the image of the blood flow along with the animation of blood flow in each thrombus category automatically. In addition, this software can process the calculation of the size of thrombus area, the maximum diameter, blood flow velocity and volume of blood flow. In this study, it can be seen that the presence of thrombus parameters can affect the volume and blood flow velocity, ie, the larger thrombus would further reduce the volume and blood flow velocity. However, the presence of thrombus, blood flow velocity and volume of blood flow has not been shown to affect the evolution of diameter of the small AAA.

Detection Signal Thrombus from Magnetic Resonance Images on Small Abdominal Aortic Aneurysms

The big risk of aneurysms on aorta is that they can leak or burst and, without treatment, this is fatal because of bleeding from the aorta into the surrounding tissues and can be reason for the sudden death. Aortic aneurysms are often associated with the thrombus in it. Magnetic Resonance Image (MRI) is one of the very best digital examinations to observe the aorta that have many small tissues. This study is to detect a thrombus in the Small AAA from MR images using DICOM-work and MatLab Software. Data were obtained from 16 patients with Small Abdominal Aortic Aneurysms (SAAA) who had been examined since July 2006 to January 2010. DICOM is the standard for Digital Imaging and Communications in Medicine that can covers most image formats for all of medicine and have specification for messaging and communication between imaging machines. T1 and T2 weighted images have been processed and used to analyze the thrombus signal. To process all the data, we use MatLab software. Algorithm to obtain images from DICOM that store in a directory was developing. Manual tracing of the borders have been done to define the Aorta Surface and Luminal Surface in order to determine the Thrombus surface, where Thrombus Surface = Aorta Surface-Luminal Surface. We found 13 of the 16 patient with SAAA had a thrombus. By using DICOM-work as intermediaries between digital examinations tool with the image processing tool is very helpful for doing image analysis

Natural Language Communication With Virtual Actor

The development of realistic virtual actors in many applications, from user interface to computer entertainment, creates expectations on the intelligence of these actors including their ability to understand natural language. Based on our research in that area over the past years, we highlight specific technical aspects in the development of language-enabled actors. The embodied nature of virtual agents lead to specific syntactic constructs that are not unlike sublanguages: these can be used to specify the parsing component of a natural language interface. However, the most specific aspects of interacting with virtual actors consist in mapping the semantic content of users’ input to the mechanisms that support agents’ behaviours. We suggest that a generalisation of speech acts can provide principles for this integration. Both aspects are illustrated by results obtained during the development of research prototypes.
