A framework for data-driven adaptive GUI generation based on DICOM
2018
Computer applications for diagnostic medical imaging provide generally a wide range of tools to support physicians in their daily diagnosis activities. Unfortunately, some functionalities are specialized for specific diseases or imaging modalities, while other ones are useless for the images under investigation. Nevertheless, the corresponding Graphical User Interface (GUI) widgets are still present on the screen reducing the image visualization area. As a consequence, the physician may be affected by cognitive overload and visual stress causing a degradation of performances, mainly due to unuseful widgets. In clinical environments, a GUI must represent a sequence of steps for image investi…
Quality Control in 3D Printing: Accuracy Analysis of 3D-Printed Models of Patient-Specific Anatomy
2021
As comparative data on the precision of 3D-printed anatomical models are sparse, the aim of this study was to evaluate the accuracy of 3D-printed models of vascular anatomy generated by two commonly used printing technologies. Thirty-five 3D models of large (aortic, wall thickness of 2 mm, n = 30) and small (coronary, wall thickness of 1.25 mm, n = 5) vessels printed with fused deposition modeling (FDM) (rigid, n = 20) and PolyJet (flexible, n = 15) technology were subjected to high-resolution CT scans. From the resulting DICOM (Digital Imaging and Communications in Medicine) dataset, an STL file was generated and wall thickness as well as surface congruency were compared with the original …
Evaluation of volumetric measurements on CBCT images using stafne bone cavities as an example
2015
Adisen, Mehmet Zahit/0000-0002-5493-8390; Yilmaz, Selmi/0000-0001-9546-6548; Yilmaz, Selmi/0000-0001-9546-6548; ATIL, Fethi/0000-0002-8286-4819 WOS: 000365269900009 PubMed: 26116844 Background: The aim of the present study is to evaluate the efficacy of CBCT in volume measuring using Stafne Bone Cavities (SBC) as an example. Material and Methods: The study was conducted with 14 subjects with SBC detected on panoramic radiographs. In order to evaluate lesions volumetric dimensions, CBCT images for each patient were captured. Files in Digital Imaging and Communications in Medicine (DICOM) format were transferred into a medical image processing program (ITK-SNAP 2.4.0) and volume in mm(3) of t…
Three-dimensional Cross-Platform Planning for Complex Spinal Procedures
2017
STUDY DESIGN A feasibility study. OBJECTIVE To develop a method based on the DICOM standard which transfers complex 3-dimensional (3D) trajectories and objects from external planning software to any navigation system for planning and intraoperative guidance of complex spinal procedures. SUMMARY OF BACKGROUND DATA There have been many reports about navigation systems with embedded planning solutions but only few on how to transfer planning data generated in external software. MATERIALS AND METHODS Patients computerized tomography and/or magnetic resonance volume data sets of the affected spinal segments were imported to Amira software, reconstructed to 3D images and fused with magnetic reson…
Comparison of digital protocols for the measurement of peri-implant marginal bone loss
2018
Background The measurement of peri-implant marginal bone loss is currently carried out using digital methods of radiographic analysis assisted by various types of software. The purpose of this study was to compare the characteristics of three different softwares: specific radiology software for the development and visualization of radiological images in DICOM format (3Dicom Viewer®), advanced level software for professional editing of bitmap images (or raster graphics) (Adobe Photoshop®), and mid-level software for processing bitmap-type images, programmed in Java and in the public domain (ImageJ®). Material and Methods It was verified that the three softwares used are valid for the measure…
SVILUPPO DI UN SERVER DICOM A BASSO COSTO CON FINI DIDATTICI E DI RICERCA
2004
PURPOSE: This paper describes our experience in developing a DICOM (Digital Imaging and Communications in Medicine) server based on widely available personal computers enabling to use X-ray digital images for teaching and scientific purposes. MATERIALS AND METHODS: The system is based on a DICOM server running on a widely used personal computer. The selected DICOM images are collected directly from the radiological equipment or from a dedicated 3D image processing workstation through a LAN connection and converted into one of the standard formats (JPEG or GIF) to allow their direct importing into multimedia presentations for teaching or scientific purposes. RESULTS: This system allows fast …
The Processing of Medical Images: Principles, Main Applications and Perspectives
2013
This chapter provides an introduction to the basic concepts of medical digital image processing. We kept the mathematical complexity of the chapter at a low level so that life science students can understand the underlying principles behind the methods of analysis and computer-assisted diagnosis.
Verwendung des DICOM- Standards in heterogener Umgebung
1999
Purpose The DICOM standard, introduced in 1993, is now established in many of today's image modalities. Experiences with DICOM implementations and requirements for future developments are described. Methods First a brief summary of the development of the DICOM standard is given. Based on general observations, different problems with installation, programming and maintenance are outlined. Results The standard consists of mandatory and optional information models and functionalities to enable the use and development of a broad spectrum of applications. But the available options lead to specific applications not compatible with the basic idea of the standard. Discussion For functional communic…
Utilidad de los informes estructurados basados en una plataforma web para el diagnóstico por imagen en patología mamaria
2015
El cáncer de mama es una enfermedad con un gran impacto sobre la salud poblacional. A pesar de los avances en esta enfermedad, la mortalidad sigue siendo elevada, por lo que es importante investigar en otros campos y herramientas como por ejemplo en el ámbito de la recogida de datos de forma estandarizada, para recoger información de forma estructurada, decisiones protocolizadas y más objetivas, mejorando esto el pronóstico de la enfermedad. Con respecto a las necesidades actuales referentes fundamentalmente a los sistemas de información, los desarrollos realizados en esta Tesis Doctoral combinan la aplicación de tecnologías y estándares de la información. La hipótesis de trabajo de esta te…
Failu augšupielādes un apstrādes sistēma IT uzņēmumam
2019
Kvalifikācijas darba mērķis ir izstrādāt failu augšupielādes un apstrādes sistēmu IT uzņēmumam. Sistēma “Failu augšupielādes un apstrādes sistēma IT uzņēmumam” ir publiska tiešsaistes sistēma, kas sniedz iespēju ieinteresētajiem lietotājiem augšupielādēt savus radioloģijas izmeklējumus uzņēmuma datu bāzē. Sistēma ļauj elektroniski augšupielādēt radioloģijas izmeklējumus, kuri ir sastopami ZIP formātā vai ierakstīti CD diskā. Sistēma tika izstrādāta galvenokārt izmantojot Go programmēšanas valodu.
