Class MultiModalitySimulator

java.lang.Object

com.pixelmed.apps.MultiModalitySimulator

public class MultiModalitySimulator
extends java.lang.Object

This class implements a multi-modality simulator that takes a database of existing studies to provide a source of sample images and DICOM attributes, and for each modality within the database, generates random new patients and studies at random intervals using the current date and time.

For example:

try {
    new MultiModalitySimulator("theirhost",11112,"STORESCP","STORESCU","database");
}
catch (Exception e) {
    slf4jlogger.error("",e);
}
 

From the command line:

java -cp pixelmed.jar:lib/additional/commons-codec-1.3.jar:lib/additional/commons-compress-1.12.jar com.pixelmed.network.MultiModalitySimulator theirhost 11112 STORESCP database
 

The database is a persistent (disk) instance of the DatabaseInformationModel, such as might be created by the RebuildDatabaseFromInstanceFiles class from a set of files, or have been created by an application storing received images in such a databaase.

The Calling AE Title used to send the images for each simulated modality is the modality string value, e.g. "CT" for images with a DICOM Atttibute Modality (0008,0060) of "CT".

The list of modalities simulated is currently limited to CT, MR, DX, CR, US, NM, XA, MG, SR, PR if present in the supplied database. This can be changed in a subclass by overriding the protected variable modalities, as can the corresponding protected variable sleepIntervalForModalityInMinutes, which needs to contain a matching number of entries.

A relatively short and contrived list of patient names is used by default, and can be overridden in a subclass by changing patientNames.
