No
The device is described as an image quality control terminal that processes, stores, and outputs electronic images of patients for radiographers. It does not perform any direct therapeutic action on a patient.
No
The device is an image quality control terminal that processes and displays medical images. Its intended use explicitly states it is "not for the purpose of doctor's diagnosis."
No
The device description explicitly states it consists of a workstation computer with keyboard, mouse, LAN interface, and display (CRT or LCD), in addition to the software for image processing and management. This indicates it is a hardware and software system, not software-only.
Based on the provided information, the REGIUS RS-1000 is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: IVD devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health.
- REGIUS RS-1000 Function: The REGIUS RS-1000 processes and manages medical images (specifically from Computed Radiography - CR devices). It does not analyze biological specimens.
- Intended Use: The intended use clearly states it receives and processes electronic images of patients.
- Device Description: The description details image processing functions, storage, display, and communication with other medical systems (RIS, HIS, PACS, film printers). These are all related to medical imaging workflow, not laboratory testing of specimens.
- Note about Diagnosis: The note explicitly states the product is "not for the purpose of doctor's diagnosis," which further reinforces that it's not an IVD used for diagnostic testing of specimens.
Therefore, the REGIUS RS-1000 falls under the category of medical imaging equipment and related software, not In Vitro Diagnostics.

Device Description
REGIUS RS-1000 is Konica Minolta Image Quality Control Terminal. REGIUS RS-1000 has the hard disk for storing the digital images. REGIUS RS-1000 consists of a workstation computer with keyboard and mouse for input, LAN interface for communication, color or monochrome CRT or LCD for displaying. REGIUS RS-1000 processes the images received from a single or multiple CR (Computed Radiography) devices with the auto gradation processing function, etc. and outputs them to one or multiples storage devices, such as the host computer or a film printer.
Note) This product is designed intended for exclusive use with a radiographer, and not for the purpose of doctor's diagnosis.
The REGIUS RS-1000 has the following feature.
- The function to do an image processing to the image data received from the CR modalities.
The kinds of the image processing are as follows:
- Adjusting the Contrast:
Achieve a clearly depicted image (with clear minimum density). - Re-sampling and Resizing
The function that re samples and resizes the image data according to need. - F-processing:
Improve dill or poorly modulated (lacking in contrast) images (to give definition to details). These process doses not affect density. - E-processing:
To improve the image that is not possible to be fully expressed by the film latitude due to the wide distribution of the subject. - H-processing
Hybrid processing is frequency enhancement processing and equalization processing based on multi-resolution analysis. - Masking
Fills in black the area on the frame where the X ray is not irradiated. - Stitching
This function that manually or automatically recognizes the long body part and assists the user to stitch each body part to create a composite image. The user checks all alignments done automatically. The image can be divided into several small images before output to a storage device or film printer. Note) This feature requires cassette type CR in addition connected.
- The function that displays all information attached with the medical image, such as patient related information, study information, and so on. The ability to confirm, modify or update this information manfully or by connecting to RIS (Radiology Information System) or HIS (Hospital Information System) is also provided.
- Images belong to the same study can be separated into different studies when necessary, and the different studies also be combined into a single study.
- The function to add or modify digital marker, grid, scale, and so on.
- The function that stores images data temporary before transferring them any further. Oldest images will be erased automatically to make sure of the hard disk capacity for continuously operation.
- The function that outputs the image data to a storage device, such as PACS (Picture Archiving and Communication System), and a film printer.
- The function that retrieves past image data from a storage device. The retrieved image data may be re-processed then output to a film printer and so on.
