MN1-5206 Rev.4 7-1.EFV mode (Option: SOP-ALPHA10-1 and EU-9102 are necessary)

7. OPTIONAL FUNCTION 7-1.

EFV mode (Option: SOP-ALPHA10-1 and EU-9102 are necessary) A compound display of an image is enabled by using an EFV (Extend Field of View) mode. With this function, a wide area that is not for one screen in a normal B mode can be observed. In addition, the EFV mode enables an image to be constructed by means of a parallel probe scan, and also a protuberant organ to be traced and its profile displayed in the form of an arc.

In order to use the EFV mode, it is necessary to assign EXTEND F-View to B mode menu on the touch panel beforehand. The probes that support this mode are: UST-9130, UST-9115, UST-5712, UST-5411, UST-5412. [Remark] The image creation process is readily affected by changes in brightness of the slice image generated by the probe scanning operation. Always pay attention to the brightness level when using this mode. When the brightness intensity varies markedly, it may sometimes be impossible to create an accurate image.

7-1-1. Switches to be used [Remark] This function enables you to assign on the touch panel and a panel with a preset. After assigning necessary functions to the touch panel and a operation panel of the equipment, start an examination.

7-1-1-1.

Touch panel

Extend F-View

: An EFV mode becomes active, if it is ON. The EFV mode is finished if the switch is pressed again.

Image ROTAT

: When an EFV image is frozen, select the image ROTATE. Rotate the rotary encoder within the range of 10 ° to 350 ° (10 ° step)to rotate the EFV image.

7-1-1-2.

Operation panel

SELECT switch

: A capture is started by pressing the SELECT switch on an EFV mode. A B mode image is mainly used after an capture ends, this is used.

FREEZE switch

: Press the FREEZE switch to finish the capture.

ZOOM switch

: Press the ZOOM switch to be able to enlarge, reduce and move the EFV image. of an EFV image are enabled. When the rotary encoder 4 is turned to the right, an EFV image is enlarged and when turned to the left, it is reduced. In addition, when the trackball is rolled, an EFV image makes a movement (Pan).

SEARCH switch

: When pressing the SEARCH switch after freeze, a white frame on an EFV image is displayed. Inside the white frame, B mode image before displaying a compound image is displayed. Because the white frame moves with the trackball or rotary encoder 4, it is moved to a desired location on thedisplay. When the B switch or the SELECT switch is pressed, a B mode image is displayed at the center.

STORE switch

: Press the STORE switch after freezing to recorde the EFV image (a still image) to a Media whitch is set as the destination to save.

MN1-5206 Rev.4 7-1.EFV mode (Option: SOP-ALPHA10-1 and EU-9102 are necessary)

7-1-2. Basic operation procedure With the EFV mode, captured B mode image is displayed as a compound. [Remark] A compound display of Flow mode is not currently supported. In addition, a measurement function is also not compatible. When an examination requires a measurement, start an EFV mode after finishing the measurement before entering into it. [Remark] Corresponding probes for EFV mode have a certain limitation. When a probe which is not corresponding to is selection, an EFV mode cannot be turned to ON. [Remark] On the EFV mode, no switching the change of DEPTH and ON/OFF of THE mode are allowed. (1)

Turn the Extend F-View (EFV Mode) on the touch panel to ON. →

B mode image is displayed. The B mode image displayed at this time is smaller than the normal B mode image. In addition, picture quality and the frame rate are different from a normal B mode image.

[Remark] Apply an adequate amount of echo jelly to the region which will be scaned to display a compound image. Move the probe to the location where a compound display is desired. [Remark] Scan it after setting STC and Gain properly so that the center of an image always becomes appropriate brightness. If the center of an image is dark, a compound image will not be properly displayed.. (2)

Press the SELECT switch on the operation panel. →

A capture for a EFV image is started. As B mode image is displayed as a compound image, scan the range that is desired with moving a probe. Then, scan it along the arranged direction of wave transducer as depicted in chart below.

[Remark] When an edge of the images which is compound travels beyond the screen, the image is automatically adjusted to fit in the screen. An image shrinks when quantity of a compound increases. [Remark] Keep the capture time less than 30 seconds at the maximum. If it is over 30 seconds, freeze is applied automatically.

(3)

Press the FREEZE switch on the operation panel. →

A capture of an EFV image is finished, and the EFV image stands still as a one screen display. Zoom, Search, and Image ROTAT operations are performed if necessary.

[Remark] When bulging organs are scanned, there are cases that the display of compound images may advance in slanted direction. In this case it can be revised with the Image ROTAT rotary function after freeze.

(4)

Press the STORE switch on the operating panel or press the PRINT switch. →

An EFV image (a still image) is saved, and a printer can output it, too.

[Remark] On the state being a compound display using EFV mode, it is not possible to save Line moving images and VideoClip moving images using the STORE switch. Save moving images with voluntary VTR peripheral equipment. (5)

Press the FREEZE switch again. →

An EFV image is erased, and it is returned to the state of (1). A compound image is displayed again in this state by pressing the SELECT switch again. When returning to a conventional B mode, turn the EXTEND F-View switch Off on this state.

MN1-5206 Rev.4 7-2.Real time 3D mode (Option: SOP-ALPHA10-4 and EU-9102 are necessary)

7-2. Real time 3D mode (Option: SOP-ALPHA10-4 and EU-9102 are necessary) Steps 1-6 below are used to perform real time 3D modes. With these functions, it is possible for an ultrasound tomogram image to be displayed in high-speed 3D. (1)

With taking-in of volume data by continuous scanning with an exclusive 3D scanner, the function can display 3D and a 3 perpendicular section image in real time.

(2)

In addition to 3D and a 3 perpendicular sections image display, there are capabilities for switching displays; one image enlarging display (1View display); one section only among 3 section images combined with 3D (2 Views display); and all displays of 3D and 3 perpendicular section images (4 Views display).

(3)

In the case of a 3D image, it is possible to rotate or shift the volume data to enable the object to be viewed from any desired direction. In addition, it is possible to switch over the zoom and rendering modes (drawing algorithm), and also to adjust the image quality, and so on.

(4)

Any three orthogonally intersecting cross-sectional images can be displayed by rotating/shifting the volume data, and also zoom, image quality, and so on, can be adjusted.

(5)

A Erase Tool is used during freeze for eliminating unnecessary artifact displayed with 3D and 3 perpendicular section images.

(6)

During freeze, it can be easy to observe fetal faces by turning volume data using a anomation film operation regenerative function for a 3D image.

MN1-5206 Rev.4 7-2.Real time 3D mode (Option: SOP-ALPHA10-4 and EU-9102 are necessary)

7-2-1. Rotation / Movement and Image display of Volume data In a real time 3D display, the positions of a viewpoint and a section are spatially fixed as shown by the charts at the left hand side below. When a 3D image is displayed as an image viewed from a viewpoint direction, to display a voluntary section as a display subject or a 3D image viewed from a voluntary direction, it is necessary for the volume data to be moved in parallel or to be rotated. To perform a translation in a real time 3D mode, the trackball during lighting of the SCAN AREA switch must be activated. With this function, the position of a section which is perpendicular can be changed by moving the interest region (a cone) from the center. This operation is operable regardless of real time or freeze. (1)
