摘要： A control unit (116) resets a time stamp value whenever a pulsation is detected. In accordance with an electric signal from an ultrasonic search unit (101) and a send/receive unit (102), the image generating unit (110) generates ultrasound image data, attaches a time stamp to the generated image data, and places it into a data storing unit (112). A contour extracting unit (113) extracts a contour within the image data stored in the data storing unit (112), generates contour data, and attaches the same time stamp as the stamp attached to the image data to the contour data. An interpolated data generating unit (114) interpolates between the contour data in accordance with the attached time stamp to generate contour data corresponding to times at which sampling was not performed. A volume calculating unit (115) calculates a left ventricular volume (LVV) of a heart from the interpolated contour data according to the Modified Simpson method.

摘要： An image compression apparatus for outputting compressed image information that is suited to progressive image reproduction where completely lossless reproduction is possible without having to use large amounts of compressed image information. A decoding apparatus decodes the compressed image information and performs reproduction. The image compression apparatus performs image compression with a first segmentation for a first plane set that includes at one bit plane in block image information in the original image information. As a result, first region information composed of segmentation information showing a first segmentation result and luminance information is produced. The image compression apparatus also performs image compression with a second segmentation for a second plane set that includes at least one bit plane adjacent to the first plane set. Here, the first segmentation result is used as a standard. As a result, second region information composed of segmentation information and luminance information is produced. Compressed image information is then generated and outputted based on the first and second region information.

摘要翻译： 一种用于输出适于逐行图像再现的压缩图像信息的图像压缩装置，其中完全无损再现是可能的，而不必使用大量的压缩图像信息。 解码装置对压缩图像信息进行解码并进行再现。 图像压缩装置对原始图像信息中的块图像信息中的一个位平面处的第一平面组进行第一分割。 结果，产生由表示第一分割结果和亮度信息的分割信息组成的第一区域信息。 图像压缩装置还对包括与第一平面组相邻的至少一个位平面的第二平面组进行第二分割来执行图像压缩。 这里，第一分割结果被用作标准。 结果，产生由分割信息和亮度信息组成的第二区域信息。 然后基于第一和第二区域信息生成并输出压缩图像信息。
