Summary
Implementing a partial picture archive and communication system (PACS) can be cost-effective. This system reduces film costs and can be amortized in 5-6 years by selecting key digital images.
Area of Science:
- Medical Imaging
- Health Informatics
- Radiology
Background:
- Diagnostic imaging departments generate substantial digital image data.
- Digital imaging techniques account for a significant portion of total examinations.
- Accurate digital storage requirements are crucial for Picture Archiving and Communication Systems (PACS).
Purpose of the Study:
- To evaluate digital image volume in diagnostic imaging.
- To determine digital storage needs for a partial PACS.
- To assess the economic viability of a partial PACS.
Main Methods:
- Analysis of daily digital imaging unit activity (CT, MRI, US, DSA).
- Quantification of images produced by digital techniques.
- Estimation of storage capacity requirements for an 800-bed hospital.
Main Results:
- Digital imaging accounts for 65-70% of total images.
- Estimated storage need is nearly 100 Gbyte/yr without compression.
- A partial PACS can be economically justified.
Conclusions:
- Reduced film-archiving costs support partial PACS implementation.
- Selection of significant images and examinations is key.
- Amortization of a partial PACS is achievable within 5-6 years.

01:40Archival Research
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze each...
