PACS three-dimensional medical image processing system source code

Three-dimensional medical image processing system (PACS) source code

System Overview:

Image archiving and communication system PACS integrates image storage server, image diagnosis workstation and RIS reporting system. It mainly consists of image processing module, image data management module, RIS reporting module, CD archiving module, DICOM communication module, film printout and other modules. , with complete image database management functions and powerful image post-processing functions, which improves the accuracy of clinical diagnosis.

System features and advantages:

Covers registration, triage, billing, report generation and distribution, etc., and is organically integrated with RIS

Acquire image data using DICOM and non-DICOM formats;

Collect original DICOM data of images through communication;

Support static and dynamic image data collection;

Supports various collection methods such as perspective collection and exposure collection;

Supports the conversion of image data from non-DICOM imaging devices into DICOM standard data;

It has the function of retaining modification traces and customizing reports and templates.

Hook up Word and other modules for report printing to achieve fully customized printing

Supports film printing management; film printing and typesetting and electronic film management can be set.

Supports 3D image processing functions; 3D reconstruction, maximum/minimum density projection, 3D volume reconstruction, 3D surface reconstruction, virtual endoscopy, surface reconstruction, blood vessel reconstruction and analysis;

Function analysis:

Multiplanar Reconstruction (MPR)

MPR is an interactive navigation in any direction of the three-dimensional volume. MPR can simultaneously display the axial, sagittal, coronal and any oblique slices, and can arbitrarily change the reconstructed position and layer thickness to facilitate the observation of the fine structures of different tissues. MPR can better display the complex anatomical relationships within tissues and organs, which is beneficial to the accurate location of lesions.

Application: Display the morphological changes of organs in various systems of the body, and various systems of the body (location of lesions, adjacent relationship, extent of invasion, relationship with large blood vessels, etc.).

Advantages: Fast reconstruction; less data loss; mixed with other reconstruction methods.

Disadvantages: single plane; low z-axis spatial resolution; volume scan data required; step-like artifacts.

Surface Reconstruction (CPR)

Definition: It is a special method of MPR, suitable for displaying some curved structural organs of the human body, such as jaws, tortuous blood vessels, bronchi, ureters, pancreatic bile ducts, etc.

Volume Reconstruction (VR)

Mask imaging was performed on all volumetric data.

VR is currently one of the most commonly used technologies in multi-slice spiral CT three-dimensional image post-processing.

Advantages: display three-dimensional structure; beautiful; widely used.

Application: All kinds of 3D reconstruction.

Virtual endoscope (VE)

Definition: Also called intracavity reconstruction technology, it refers to adjusting the CT threshold and tissue transparency. It is not necessary to observe the tissue transparency to 100% and eliminate its image; it is necessary to observe the tissue transparency to 0, retain its image, and then adjust the artificial false color. Obtain similar fiberscope images and rely on navigation methods to display intraluminal structures.

Advantages: Non-invasive, showing the inner surface structures of hollow organs, airways, and blood vessels.

Application: Simulated colonoscopy, gastroscopy, bronchoscopy.

Function introduction

● Appointment registration workstation

Achieve the goal: Arrange and register patients to make appointments for examinations, and record information including examination date, time, clinic, clinical impression, medical history, cost and other information for the imaging department to write reports.

●Digital collection workstation

Functions include: connecting to DICOM imaging equipment, receiving DICOM image information through the gateway program, compressing and packaging it and finally transmitting it to the PACS imaging center.

●Video collection workstation

Functions include: connecting non-digital imaging equipment, such as X-ray machines, ultrasound, speculum, etc., through video interfaces, digitally converting them through image acquisition cards, combining description information and storing them into standard DICOM image formats, and finally transmitting them to the PACS imaging center. Reports can be written directly.

● Scanning and collection workstation

Functions include: digitizing existing films with a high-resolution professional (medical) scanner, storing the description information into a standard DICOM image format, and finally transmitting it to the PACS imaging center. Reports can be written directly.

● Film reading and reporting workstation

Functions include: radiologists read films, write diagnostic reports, and print out diagnostic reports for patients

● System maintenance workstation

Functions include: Administrators perform daily system maintenance work on the PACS system, such as performance monitoring, system tuning, data backup, etc.
