    MN2‑0218 SECTION 4 Principle of System Operation 4-5-6. DIU The B/W DIU (Digital Imaging Unit) fetches ultrasound wave digital data coming from the GEU in synchronized with the DIU clock, writing ultrasound wave data to the display memory in XY writing method, then reading out the ultrasound wave data in synchronized with the TV signal.
  • Page 68 MN2‑0218 SECTION 4 Principle of System Operation Echo Erase In order to make physiological signals easy to see, the bottom portion of ultrasound M image data is erased. The erased portion of ultrasound image data is written to image memory as "0" level. This differs from USERASE and ERASE in the point that it is executed when ultrasound image data are stored in image memory.

  • Page 69: Post Process

    MN2‑0218 SECTION 4 Principle of System Operation Erasing is executed by flash write at 160 nsec/1 Row, but when 4 chips are working simultaneously, erasing can be done at high speed, with one 512 x 512 pixel screen erased in approx. 45 µsec. Furthermore, since it is not dependent on ultrasound image data write operations, it differs from USERASE, ECHO ERASE and Memory Erase.
  • Page 70 MN2‑0218 SECTION 4 Principle of System Operation RAM, so selection is made by rewriting the Enhance RAM. Furthermore, for ultrasound M image data, Standard (Linear) is selected automatically. This function is implemented for black and white images only. Overlay display This is for displaying character and graphic.

  • Page 71: Write Control

    MN2‑0218 SECTION 4 Principle of System Operation This function makes the B image display area narrow and increases the frame rate. This is accomplished by varying BOF/, EOF/ and DSCADRS (8:0) in the GEU. Data from BOF/ to EOF/ are written as DIU. Freeze Function This function stops the writing of an image to display memory.

  • Page 72: Display Control

    MN2‑0218 SECTION 4 Principle of System Operation image can be developed in a 4096 x 4096 area, but in reality, the memory area where ultrasound data can be written is only 512 x 512 in size. Therefore, the virtual write area is regarded as off screen area and the writing operation is not performed.

  • Page 73: Timing Generator

    MN2‑0218 SECTION 4 Principle of System Operation display begins, then in accordance with the display area signal, reading of display data from the SAM block is carried out. In the case of complex display, in order to display Left-Right 2 screen main memory according to the display format, while TV display of screen 1 is being carried out, data for display of screen 2 are being transferred to the SAM block (Real Time Read Transfer) to carry out complex display.

  • Page 74: Clock Generator

    MN2‑0218 SECTION 4 Principle of System Operation CLOCK GENERATOR The reference clock generated by the crystal oscillator is divided and 25 MHz, 12 MHz and 6 MHz synchronization clocks are generated. An A/D conversion clock is also generated as a countermeasure for jitter during A/D conversion. Jitter during A/D conversion occurs because the operating frequencies of the GEU and DIU are not synchronized.
