CD and DVD Functions

1 Description

The CD/DVD allows you to store DICOM images and a CD Viewer to a CD-R or DVD-R media that can be played back on a PC or laptop with a Windows™ 2000 or XP operating system. Images stored on a CD-R or DVD-R can be restored to the AW system or MR EXCITE HD system.

The CD/DVD interchange system is not considered part of the archive system but rather an ancillary storage device designed for sending select images or an entire exam to referring physicians. When an exam/series/ image is burned to a CD-R or DVD-R, the system does not consider the exam/series/or image as archived. Therefore, the archive column on the Browser does not change its state based on CD/DVD interchange activity.

The system does not know if a CD-R or DVD-R is in the drive until the copy action begins. Therefore it is necessary to note the size of the files you are selecting so that you do not exceed the media capacity. The approximate maximum capacity for a CD-R is 500MB and the approximate maximum capacity for DVD-R is 4 GB. The cumulative file size to be copied is displayed in the message/progress bar area of the CD/DVD Composer (see Figure 1).

2 CD and DVD Media Considerations

A recordable CD (CD-R) or DVD-R can only be recorded once. All image data that you want to record on a given CD-R or DVD-R must be selected beforehand, and will be recorded in a single pass. It is not possible to add data on a CD-R or DVD-R.
When recording DICOM image data on a CD-R or DVD-R, you must always use a BLANK media.
Once you have started recording, click [Quit] to close the interface. The system continues to burn data to the CD/DVD in the background. To view the CD/DVD window, click [CD/DVD] from the Browser list of programs. Note that the list of items is blank. View the progress bar to note if the burning process is finished.
Image data can also be recorded on CD-R in PDF or HTML format, using the Data Export function.
Recordable CDs are considerably more sensitive to damage than the conventional CDROMs that you may be familiar with. Respect the handling instructions below.

notice

To avoid image loss, never touch the recording surface of a recordable CD (CD-R). Handle the disk only by the outer edge or central hole. Do not place it face down on a hard surface. Fingerprints or scratches will make the disk unusable.

Store the disk in the protective case. Proper storage helps protect the data from damage due to scratches on the disk surface.
Do not leave the disk in direct sunlight or in a hot, humid environment. These conditions can warp and damage the disk.
Use only a felt tip permanent pen when labeling. Write only on the clear inner diameter of the disk (or the printed area of a CD-R). Never use a ballpoint or hard point writing tool as it may damage the disk. Do not use adhesive labels.
Use a soft, lint-free cloth to remove spots, dust, or fingerprints from the disk. Always wipe from the center to the outside edge of the disk. Never wipe the disk in a circular motion.
Do not use any chemical-based cleaners. These can damage the disk.
Do not use the CD/DVD program to permanently store your MR data. If the CD/DVD is scratched there is no recovery of the data.

3 Saving Images to CD-R or DVD-R

6.1 Data Export

Data Export allows you to either store or ftp MR images as JPEG, PNG, AVI, MPEG or MOV formats. The files can only be burned to a CD-R and only one report can be burned at a time. Once a CD-R has been burned, you cannot add more reports. In other words, it is a burn once process and not a re-writable process.

The JPEG, PNG, AVI, MPEG or MOV images can be viewed from a PC or laptop with a WindowsTM 2000 or XP operating system using Internet Explorer 5.5 or later.

There are two tabs on the Data Export window: Compose and Export. The Compose tab allows you to define the compression factor, annotation level, W/L, scroll, zoom, and output format for the series you want to export. The export tab is a list of all the exams and series you have in the Data Export program. This means that you can compose a series and then export it to either a CD or ftp site at a later date. Exams and series stay in the Export program until they are actively deleted.

6.1.1 Compose Tab

Table 1. Compose Tab Details
No.	Selections	Description
1	Selection	Selection displays the Patient Name, Exam and Series number, the number of images in the series, the file size of the images with the current compression selection and matrix size.
1	Conversion Format	Conversion Format is a pull-down menu from which you can select the image format for the currently selected data set. Format choices are: JPEG, PNG, AVI, MPEG, and MOV. AVI, MPEG, and MOV are all movietype formats. Choose the format that is compatible with the movie player on your PC or laptop.
2	Compression Factor	Compression Factor only applies to JPEG and MPEGs. The lower the number, the less the compression, the higher the image quality but the larger the file.
2	Image/Sec	Image/Sec is movie play back speed and therefore it is only applicable for MPEG, AVI or MOV files.
3	Image Range Selection	Image Range Selection allows you to select the images you want to place in the designated folder. For example, if you have a multi-phase series selected and all you want is the first phase in the MPEG, then select the range of images representing phase 1 of your data set. The ability to select a subset of images from the selected series is particularly important if you plan to ftp the files rather than burn a CD.
4	Annotation	Annotation allows you to set the level of annotation for the images: none, full, partial (a subset of the full annotation) or custom which activates the Customize button. Click to display a pop-up window from which you can turn on specific annotation fields.
5	Propagate	Series selection buttons allow you to navigate through series within the exam. Propagate Image Operations allows you to apply the image manipulations (W/L, zoom, scroll) you’ve performed on all images forward from the currently displayed image within a series.
6	Play/Stop	Click Play to preview the MPEG, AVI, or MOV file. Click [Stop] to quit playing the movie.
7	Quit	Click Quit to close the Data Export window.
8	Image area	The image area displays the current images by scrolling through them in a cine loop. Use the keyboard Page Up and Page Down keys to move through the images manually.
9	Report Name	Report Name appears at the top of the report that will be created once you execute the data export. It also appears in the Export data list. Typically the patient’s name and type of file are entered as the Report Name. There can be no spaces or characters other than alpha numeric.
9	Folder Name	Folder Name is the name of the folder to which you want to file the Report Name. From the Export tab, you can view the data listed within each folder. The data within a folder is sorted by file type. For example, if you added 10 JPEGs from the T1 series and 20 JPEGs from the T2 series you will see a list of 30 JPEGs in that folder. If you want these JPEGs separated, you must place them in separate folders.
10	Anonymous	Click the Anonymous box and the images added to the report will have the patient’s name replaced with Anonymous and the exam number.
	Add to Report	Add to Report adds the current data set to the report from which you can either burn the information to a CD-R or ftp it to an IP address. A Data Conversion progress window appears once you click [Add to Report]. Click [Cancel] if you want to stop the data conversion.

6.1.2 Export Tab

notice

It is important to note that reports stay listed in the Export tab until you remove them. Consider the length of time you need to keep the file in the program based on if you need to burn another CD-R or ftp the report more than once.

Table 2. Export Tab Details
No.	Selection	Description
1	Report Name list	The list of all the report names in the data base.
2		Highlight an item in any of the list displays (Report, Folder, or Type) and click the Delete icon to remove the item from the list. Items remain on the list after you Quit Data Export until they have been deleted through this method.
3	Folder Name list	This list identifies all the folders associated with the report name. Note the file size to make sure you can ftp the file or store it on a single CD-R.
4	Move to	The Move to selection allows you to move the currently highlighted item to a destination of your choice. For example, you can highlight an item in the Type list and add it to a particular folder in the Folder list. The size of the data that comprises each folder is listed.
5	Type Name list	The list of all the file types within the highlighted folder. Keep in mind, that the only items displayed in the list are the item types. If, for example, you added 20 T1 JPEG images to Folder 1 and then added another 20 T2 JPEG images to Folder 1, the number of JPEGs in folder 1 is 40. The quantity and size of each data type is listed.
6	Quit	Click Quit to close the window.
7	Report Name	The name of the report that you are going to export. Select the report from the pull-down menu.
8	Comment	Type in a comment that appears on the report. Do not apply a carriage return when typing. The text will wrap automatically when appropriate for the finished report.
