Slide Set: Reproducible image analysis and batch processing with ImageJ.

Abstract: Most imaging studies in the biological sciences rely on analyses that are relatively simple. However, manual repetition of analysis tasks across multiple regions in many images can complicate even the simplest analysis, making record keeping difficult, increasing the potential for error, and limiting reproducibility. While fully automated solutions are necessary for very large data sets, they are sometimes impractical for the small- and medium-sized data sets common in biology. Here we present the Slide Set plugin for ImageJ, which provides a framework for reproducible image analysis and batch processing. Slide Set organizes data into tables, associating image files with regions of interest and other relevant information. Analysis commands are automatically repeated over each image in the data set, and multiple commands can be chained together for more complex analysis tasks. All analysis parameters are saved, ensuring transparency and reproducibility. Slide Set includes a variety of built-in analysis commands and can be easily extended to automate other ImageJ plugins, reducing the manual repetition of image analysis without the set-up effort or programming expertise required for a fully automated solution.

Transfer of digital medical images and data

Abstract: A system for distributing images creates a self-sufficient, self-consistent medical imaging and other medical information transfer file that contains image files and corresponding data sets that are bundled with an image viewer application. The medical image and data transfer file is prepared using object serialization and contains a deserialization application. The transfer file is created at an origination location and transmitted to a destination device as a packaged file over a computer network. The destination device receives the packaged file from the origination location and executes the viewer application with the image files and the data sets by opening the packaged file alone, without the need to run any other imaging/viewer application at the destination device. The viewer application has image viewing panes, an annotation tool, and image manipulation tools.

Method of integrating a picture archiving communication system and a voice dictation or voice recognition system

Abstract: A method for integrating a picture archiving and communication system (“PACS”) and a voice dictating or speech recognition system (collectively “voice dictation system”) is provided. The method includes logging in to a PACS. The method also includes automatically logging in to a voice dictation system responsive to the logging in step and opening an image file in the PACS. The integration method further includes automatically creating a dictation file associated with the image file in the voice dictation system responsive to at least one of the logging in step, the automatic logging in step or the opening step. The method may optionally include sending a predetermined identifier to the dictation file to associate the image file with the dictation file. The method may additionally optionally include performing the automatic logging in step responsive to the PACS being in a dictation mode. In another exemplary embodiment of the invention, the method for integrating the PACS and a voice dictation system includes issuing a save command for a dictation file and saving the dictation file to memory. The method further includes automatically saving the image file responsive to at least one of the issuing step or the saving step. The method also includes automatically opening an image file in the PACS responsive to at least one of the issuing step, the saving step or the automatic saving step.

Virtual microscopy and public-key cryptography for Internet telepathology.

Abstract: The Internet is a potentially inexpensive, widely available medium for telepathology, but there are concerns about its reliability and security. Using a digital camera, 41 photomicrographs of transbronchial biopsies, at 100 optical magnification, were captured and digitized at 2700 image files were saved in JPEG format at medium compression, attached to text files with patient information, encrypted for security in the S MIME format using a digital signature and digital envelope, and transmitted by email. Received email files were decrypted automatically and the images viewed with standard software. Telepathology diagnoses were compared with original interpretations. The images averaged 810 kByte in size. The encryption and decryption did not cause significant delays in overall transmission time and, together with transmission, did not produce noticeable image degradation. The received image files could be viewed in a manner that simulated light microscopy. There was agreement between telepathology and or...

Efficient synchronization of changes to images

Abstract: A change to an image is synchronized. A modified image is obtained at a first device where the modified image is associated with modified metadata. The modified metadata is stored in a store associated with the first device. The metadata is sent from the first device to a second device, where the modified image is able to be generated on the second device using the modified metadata and a preexisting image file on the second device.
