| 摘 要： | IntroductionWith the development of medical imagingtechniques,many devices such as computed tomo-graphy,positron emission tomography,singlephoton emissioin computed tomography,magneticresonance imaging,and ultrasound scanners arewidely available for capturing the planar images ofhuman organs directly in machine- readable form.These medical imaging methods bring a lot of ad-vantages to clinical diagnosis and treatment.How-ever,due to these systems'2 - D imaging modali-ties,it is difficult to un…

| Abstract: | The volumetric rendering of 3 D medical image data is very effective method for communication about radiological studies to clinicians. Algorithms that produce images with artifacts and inaccuracies are not clinically useful. This paper proposed a direct voxel projection algorithm to implement volumetric data rendering. Using this algorithm, arbitrary volume rotation, transparent and cutaway views are generated satisfactorily. Compared with the existing raytracing methods, it improves the projection image quality greatly. Some experimental results about real medical CT image data demonstrate the advantages and fidelity of the proposed algorithm. |
