First, main ultrasonic wave receiver 306 and subordinate ultrasonic wave receiver 308,310 need to be redefined for main device or slave unit.First kind of way sets via hardware mode, main ultrasonic wave receiver 306 is set as main device by the first switch 3066, subordinate ultrasonic wave receiver 308 is set as slave unit by the second switch 3086, and the switch (not shown) that subordinate ultrasonic wave receiver 310 is had by it is set as slave unit.In one embodiment, first switch 3066 and the second switch 3086 are jumper wire device (Jumper), therefore by setting jumper wire device, main ultrasonic wave receiver 306 and subordinate ultrasonic wave receiver 308,310 are set as main device or slave unit.
Main ultrasonic wave receiver 306 and subordinate ultrasonic wave receiver 308,310 are set as main device or slave unit by software or firmware by the second way.User can pass through a control software design 3130(of host apparatus 312 as shown in Figure 3) set, more particularly, control software design 3130 comprises an application program (Application) and a driver (Driver).Application program has a User's Interface (User Interface; UI).After user is set by the User's Interface of application program, processor 3120 by the buffer in the internal storage access controller (not shown) of the buffer in the second internal storage access controller 3084 of the buffer in the first internal storage access controller 3064 of the main ultrasonic wave receiver 306 of described driver settings, subordinate ultrasonic wave receiver 308 and subordinate ultrasonic wave receiver 310, so that main ultrasonic wave receiver 306 and subordinate ultrasonic wave receiver 308,310 are set as main device or slave unit.
After above-mentioned setting, can start to carry out ultrasonic data acquisition.One ultrasonic delivery unit (not shown) is via ultrasound scanner head 300, 302, 304 send ultrasonic signals, first analog to digital converter 3060 of main ultrasonic wave receiver 306, the ultrasound scanner head 300 that second analog to digital converter 3080 of subordinate ultrasonic wave receiver 308 and the analog to digital converter (not shown) of subordinate ultrasonic wave receiver 310 couple separately via it, 302, the reflected signal of the above-mentioned ultrasonic signals of 304 reception, also namely ultrasound scanner head 300 is received, 302, described multiple analog scan signal is also converted to multiple digital scanning signal by multiple analog scan signal of 304, described multiple digital scanning signal is stored in the second internal memory 3062 of main ultrasonic wave receiver 306, in 3rd internal memory 3082 of subordinate ultrasonic wave receiver 308 and the internal memory (not shown) of subordinate ultrasonic wave receiver 310.Main ultrasonic wave receiver 306 of the present invention and subordinate ultrasonic wave receiver 308, 310 via respective independently first interface 316 and the second interface 318, 320 root complexs 3122 being electrically coupled to host apparatus 312, therefore under the control of the first internal storage access controller 3064 of main ultrasonic wave receiver 306, main ultrasonic wave receiver 306 and subordinate ultrasonic wave receiver 308, 310 respectively via first interface 316 and the second interface 318, digital scanning signal is sent to root complex 3122 by 320, by root complex 3122, digital scanning signal is write the first internal memory 3124 of host apparatus 312 again, finally read digital scanning signal from the first internal memory 3124 and be sent to Graphics Processing Unit 3126, signal of video signal signal of video signal is sent to display device 3128 for display is produced according to digital scanning signal by Graphics Processing Unit 3126.
Due to main ultrasonic wave receiver 306 and subordinate ultrasonic wave receiver 308, 310 do not share same-interface, so main ultrasonic wave receiver 306 and subordinate ultrasonic wave receiver 308, 310 can so that independently frequency range and root complex 3122 carry out data transmission, for host apparatus 312, the number of channel increases (three ultrasonic wave receivers) and does not need shared frequency range, and in existing ultrasonic data acquisition system 20 described in Fig. 2, although the number of channel of ultrasonic receiving element 200 can be increased, but the frequency range of interface 204 can only be shared, therefore ultrasonic data acquisition system 30 of the present invention has better extendibility, as long as the interface quantity of host apparatus 312 is enough, ultrasonic wave receiver quantity can expand along with interface quantity.
In addition, the analog to digital converter (not shown) of the first analog to digital converter 3060 of main ultrasonic wave receiver 306 and the second analog to digital converter 3080 of subordinate ultrasonic wave receiver 308 and ultrasonic wave receiver 310 is for can select assembly, when ultrasound scanner head 300,302,304 directly transmits digital scanning signal, then can not need the analog to digital converter (not shown) of the first analog to digital converter 3060 of main ultrasonic wave receiver 306, the second analog to digital converter 3080 of subordinate ultrasonic wave receiver 308 and subordinate ultrasonic wave receiver 310.
Host apparatus 312 can be a personal computer (Personal Computer; PC), first interface 316 and the second interface 318,320 are a high speed date transfer bus interface, connect (Peripheral Component Interconnect Express such as but not limited to high speed perimeter component; PCI-E) interface, main ultrasonic wave receiver 306 and subordinate ultrasonic wave receiver 308,310 module can turn to the form of adapter respectively, and such as module turns to high speed perimeter component connecting adapter, therefore very convenient in expansion.In another embodiment, processor 3120, root complex 3122, first internal memory 3124, Graphics Processing Unit 3126 and display device 3128 can independently arrange and need not be integrated into personal computer.
Because main ultrasonic wave receiver 306 and subordinate ultrasonic wave receiver 308,310 are linked up respectively by first interface 316 and the second interface 318,320 and root complex 3122, therefore in ultrasonic data acquisition system 30 of the present invention, main ultrasonic wave receiver 306, subordinate ultrasonic wave receiver 308,310 and the sequential control between root complex 3122 and synchronously just seem important.
