Ikaros, (548.4kB)

The Ikaros software integrates an intuitive graphical user interface with a range of potent processing tools, delivering the necessary flexibility in the process of karyogram creation. Engineered to reduce the number of interactions, Ikaros holds the potential to decrease the time needed for both analysis and result review compared to a manual workflow.

Ikaros offers tools to assist cytogeneticists in evaluating metaphases prepared using various prevalent chromosome banding methods (such as G-Banding and Q-Banding). It also supports diverse specimen types, including peripheral blood, bone marrow, amniotic fluid, and chorionic villi.

Moreover, Ikaros introduces a color fluorescence mode, displacing traditional photography and eliminating the time-consuming and laborious processing steps typically performed in a darkroom. Color images are produced by sequentially capturing monochrome images of the distinct color components and then automatically combining them to form a cohesive color image. The automated integration time control guarantees accurate exposures from the initial shot, eliminating the need for cumbersome test exposures or guesswork in determining the correct integration time. This not only reduces hands-on time but also extends the lifespan of the specimen. Even faint fluorescent signals against a strong counterstain result in clear and sharp images.

DNN-Based Karyogram Creation

The latest versions of Ikaros by MetaSystems have integrated features based on Deep Neural Networks (DNNs), designed to assist cytogeneticists in segmenting metaphase chromosomes and classifying them within the karyogram. This cutting-edge technology supersedes the respective algorithms used in earlier versions of Ikaros, offering the potential to markedly decrease the number of interactions needed in comparison to the former workflow.

Like its predecessors, the latest versions of Ikaros support users in separating chromosomes in the metaphase. However, the adoption of a DNN-based workflow marks a notable progression in this process, aiming to lower the rate of segmentation errors and consequently lessen the need for manual corrections by the users.
This introduces the deployment of the new DNN-based tools as an additional means to achieve time savings in metaphase processing.

In the process of karyogram creation, another traditionally laborious task is the classification of chromosomes into their appropriate classes on the karyogram form. DNN technology also aids in this step, reducing the need for manual input and corrections. As a result, cytogeneticists are presented with an initial karyogram draft. This draft serves as a working basis for the adjustments and evaluation performed by the experienced professional.

Q&A

Question: Does the new Ikaros equipped with DNN capabilities fully automate the creation of karyograms?
Answer: No. In the new Ikaros, the DNN capabilities facilitate the segregation of chromosomes and their categorization into the appropriate karyogram classes. This process yields a preliminary suggestion that requires further assessment and potential modification by a skilled user. Ultimately, the cytogeneticist is responsible for creating the final karyogram and conducting its analysis.

Question: Can I change the results of the DNN-based chromosome segregation and assignment?
Answer: Yes, once Ikaros generates a karyogram proposal via its DNN features, users have the possibility and the responsibility to review and, if needed, amend this proposal. They have access to the same respective tools that have been present in earlier versions of Ikaros. Nevertheless, when an appropriate DNN is utilized, it is anticipated that the need for manual adjustments will be considerably reduced compared to the machine learning algorithms used in prior versions.

Question: How much time will the new DNN-based functions save me per case or per karyogram?
Answer: The response to this inquiry is contingent on various elements. Factors such as the nature of preparations, working methods employed, and the time allocated for result verification and reporting all play crucial roles in determining processing time. Nonetheless, insights from laboratories that have adopted the new feature indicate a noticeable decrease in case processing times, attributed to the diminished requirement for manual intervention in contrast to the algorithms previously in use.

Question: Is it necessary to replace my current Ikaros installations to access the new functionalities?
Answer: No, there is no need for a replacement. Starting with version 6.3, every new version of Ikaros comes ready for DNN-based chromosome separation and classification and can be upgraded to include this feature. For efficient handling of DNN operations, an additional graphics card is needed to facilitate the computations. This card can be installed directly in the workstation or in a distinct system.
