Description: DICOM是Digital Imaging and COmmunication of Medicine的缩写，是美国放射学会(American College of Radiology，ACR)和美国电器制造商协会(National Electrical Manufacturers Association，NEMA)组织制定的专门用于医学图像的存储和传输的标准名称。经过十多年的发展，该标准已经被医疗设备生产商和医疗界广泛接受，在医疗仪器中得到普及和应用，带有DICOM接口的计算机断层扫描(CT)、核磁共振(MR)、心血管造影和超声成像设备大量出现，在医疗信息系统数字网络化中起了重要的作用,在实际使用过程中,需要将它的图像转换成bmp格式.本例实现了这样的功能-DICOM is the Digital Imaging and COmmunication of Medicine of the initials, Radiological Society of the United States (American College of Radiology, ACR) and American Electrical Manufacturers Association (National Electrical Manufacturers Association, NEMA) developed by the Organization dedicated medical image storage and transmission of standard name. After ten years of development, has been the standard of medical equipment manufacturers and the medical profession widely accepted in the medical equipment to be universal and applications, with a DICOM interface computed tomography (CT), nuclear magnetic resonance (MR), angiocardiography and ultrasound imaging equipment, the appearance of large numbers of medical information systems and digital networks play an important role in the actual use of the process, it needs to be converted into bmp format images. realize in this case such a function Platform: |

Description: 超声视频图像需要实时地采集并在处理后在显示器上重建，图像存储器就必须不断地写入数据，同时又要不断地从存储器读出数据送往后端处理和显示[11]。为了满足这种要求，可以在采集系统中设置2片容量一样的SRAM，通过乒乓读写机制来管理。任何时刻，只能有1片SRAM处于写状态，同时也只有1片SRAM处于读状态。工作期间，2片SRAM都处于读写状态轮流转换的过程，转换的过程相同，但是状态错开，从而保证数据能连续地写人和读出祯存.-Real-time ultrasound video images need to collect and deal with the reconstruction after the display, image memory must be continually write data, while at the same time continuously sent from the memory读出数据back-end processing and display [11]. To meet this requirement, you can set up collection system capacity of two different SRAM, read and write through the ping-pong mechanisms to manage. At any time, can only have a SRAM in write state, but also the only one at a time the state of SRAM. Work, two SRAM read and write are in the process of converting a state of rotation, the conversion process of the same, but the state staggered to ensure that data can be continuously written and read out Qizhen depositors.

Description: Ultrasound Speckle Reduction Using Coded Excitation and Pulse Compression
Ultrasound images are riddled with system dependent imperfections called speckle (multiplicative noise). In ultrasonic imaging, detection of small lesions could be difficult because the effects of speckle may mask the visibility of these small targets. Therefore, the purpose of this project is to decrease speckle while maintaining some of the key salient features in the image. Images of tissue-mimicking phantoms will be created using Field II [1-2] in MATLAB (Natick, MA). Image quality metrics such as speckle signal-to-noise ratio (sSNR) [3] and contrast-to-noise ratio (CNR) [4] will be used to quantify improvements in image quality after various despeckling filters have been applied.
