The specific embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
Method provided by the invention mainly comprises: obtain the ultrasonic beam data of Beam-former output in the local diagnostic ultrasound equipment, be transferred to long-range diagnostic ultrasound equipment after these ultrasonic beam data are compressed; Long-range diagnostic ultrasound equipment carries out decompress(ion) to the ultrasonic beam data after compressing, and the ultrasonic beam data behind the decompress(ion) are carried out the conversion of beam space coordinate to real space coordinate, obtains display image data.
When adopting said method, be that the ultrasonic beam data of the image correspondence shown in (a) among Fig. 2 are compressed and transmitted, only comprise physiologic information in the ultrasonic beam data, still do not have to occur the corresponding view data of part outside (b) middle sector region, the ultrasonic beam data are compressed and transmitted obviously can conserve network bandwidth with respect to display image data is compressed and transmits.
Because after human organ is scanned, can relatively be concerned about the key position or the disease sites of organ, therefore, after the ultrasonic beam data of obtaining Beam-former output, determine the care zone (ROI in these ultrasonic beam data, Region of Interest), when the ultrasonic beam data are compressed, can carry out lossless compression to being concerned about the ultrasonic beam data in the zone, carry out lossy compression to being concerned about the ultrasonic beam data outside the zone, thereby raising compression ratio, conserve network bandwidth more.Correspondingly, in long-range diagnostic ultrasound equipment, to being concerned about the ultrasonic beam The data decompress(ion) mode corresponding in the zone, to being concerned about the ultrasonic beam The data decompress(ion) mode corresponding outside the zone with lossy decompress(ion) with lossless compression.
When the care in determining the ultrasonic beam data is regional, can be according to the care zone in the definite in real time ultrasonic beam data of user's demand, for example, the user can be according to the shown image that goes out of display in the local diagnostic ultrasound equipment, determine to be concerned about the zone by input control order, and this control instruction is transferred to long-range diagnostic ultrasound equipment; Also can determine care zone in the ultrasonic beam data for example, if human heart is scanned, can preestablish the key position of human heart according to predefined strategy, the ultrasonic beam data of this key position correspondence be set to be concerned about the zone; Also can adopt network bandwidth state, determine that the care zone in the ultrasonic beam data waits other to determine mode according to reality.
Wherein, the care zone of determining can be a plurality of zones in the image, each area schematic in the ultrasonic beam data that Fig. 3 provides for the embodiment of the invention and the image of display image data correspondence, wherein, (a) be each area schematic in the image of ultrasonic beam data correspondence, (b) be each area schematic in the image of display image data correspondence, the care zone of determining is area 01 and area 02 in (a), wherein, area 01 correspondence is zone 11 in (b), and area 02 correspondences are zone 22 in (b).Only one of them example shown in Fig. 3, not in order to restriction the present invention.
In addition, when the real network limited bandwidth, in order to guarantee to be concerned about that the zone has higher definition in display image, reduce factors such as network bandwidth deterioration to being concerned about the influence of regional definition, can compress with first frame per second being concerned about the corresponding ultrasonic beam data in zone, the ultrasonic beam data of being concerned about zone part correspondence are in addition compressed with second frame per second, and wherein first frame per second is greater than second frame per second.The value of first frame per second and second frame per second can be carried out real-time adjustment according to the wideband condition of reality; Correspondingly, long-range diagnostic ultrasound equipment adopt first frame per second to be concerned about the zone accordingly the ultrasonic beam data decompress, adopt second frame per second that the corresponding ultrasonic beam data of part beyond being concerned about the zone are decompressed.
DSC carries out the process from the beam space coordinate to real space Coordinate Conversion the ultrasonic beam data, at first the ultrasonic beam data map is formed scanning element behind real space coordinate, because each scanning element on the real space coordinate be not pixel on the real space coordinate, and have only pixel can constitute display image data and on display the form with image show, therefore, needing to adopt the scanning element adjacent with pixel to carry out difference calculates, for example, can adopt 4 scanning elements that close on most with pixel to carry out difference calculates, thereby obtain each pixel, data by each pixel correspondence constitute display image data, wherein, calculate a scanning element number that pixel adopted by default converse routine decision.As shown in Figure 4, the scanning element that the ultrasonic beam data map forms to the real space coordinate is the cross point among the figure, and the round dot on the real space coordinate is a pixel, when ultrasound probe is arcuate probe or phase battle array probe, utilize scanning element to carry out the formed image of pixel that difference calculates and be generally fan-shaped, in this sector region, the density of the near field part scanning element density than pixel usually is big, and the density from the near field part to far field part scanning element reduces gradually, wherein, the near field part is meant the upper part of sector region, and the far field part refers to the end portion of sector region.Carrying out difference with 4 scanning elements, to calculate a pixel be example, pixel 41 among the figure can utilize its scanning element that closes on most 42,43,44 and 45 carry out difference calculates, other pixel is also adopted in a like fashion and is obtained, will occur some scanning elements does not so contribute to the calculating of pixel, that is to say that some scanning elements can not be used to carry out difference and calculate, the scanning element among the figure 46 for example, so, because can not being used to carry out the scanning element that difference calculates, these can not impact display image data, before the compression of carrying out the ultrasonic beam data, can according to predetermined strategy will can not be used to carry out scanning element that difference calculates with 0 or the scanning element that is adjacent replace, thereby further improve compression ratio.
Because after the type of ultrasound probe is determined, just there are certain mapping relations in ultrasonic beam data and display image data, be that scanning element and pixel exist certain mapping relations, utilize these mapping relations can determine which is to be used to carry out the data that difference is calculated in the ultrasonic beam data, so, above-mentioned predetermined strategy can be according to the designed algorithm of mapping relations between scanning element and the pixel, does not repeat them here.
