Working with Data

The Sonix RP has many different types of data that can be stored. The imaging mode determines the type of data that is available to store at any given time.

Cine Buffer
The cine is programmable, but defaults 128MB. The number of frames of data that can be stored in the cine depends on:
 * Data type
 * Imaging depth
 * Imaging sector & line density

If the cine size is changed, caution should be taken as to not over-allocate the system with memory beyond it's capacity, otherwise sluggishness of the interface will result. An on-screen cine control acts as an interface to the current displayed frame, as well as determining what frames shall be stored to disk. The control can be selected using the SELECT button, and then the trackball will be able to scroll through the frames. The display is organized as follows: Current / Total [ Start … End ]

The start and end frames for storing data or playing back the cine can be set by clicking on the Start and End numbers of the cine, and then scrolling the values using the trackball. Once the range has been selected, the record button on screen (a round circle with a smaller circle inside), can be clicked on to bring up the Data Storage screen.

Storage Screen
The Data Storage screen is used to select the types of data that are desired to be stored to disk. A filename can be entered, however the default name is the current time at which the record button was clicked. The requested frame range will be initialized with the values adjusted from the cine control, however they can be modified in this screen as necessary. The default extensions for the data types are given within the screen.

All data types will be displayed, however, only the ones that are available in the current imaging mode will have a value of ‘Yes’ in the Available column, as well as a non-zero frame count in the Frames column.

To speed collection up, data types can be selected by default when the Data Storage screen is displayed. To do this, check off the data types that should be defaulted, and click on Set Selection As Default. All data is stored under the D:\PatientInfo. If a patient and study have been created, then the data is under a folder with the naming convention of: D:\PatientInfo\Patient ID\Study Date\. If there is no patient selected then the data will be stored under D:\PatientInfo\.~default\Study Date\.

MATLAB Integration
Whenever data is stored, a MATLAB icon corresponding to the data type saved will appear on the bottom of the screen assuming thumbnail selection is turned on. Clicking on this icon will open the first image in the series in MATLAB as shown below.

Data Types
There are many data types that can be stored on the Sonix RP, a few important notes when reading the table:
 * 1) Frame size calculations are in bytes.
 * 2) Data types that have a frame size starting with 'FC' indicate that the data comes from the cine, and the frame counter may be stored with the data, this is an option and can be turned on or off
