The device description explicitly mentions "Quantib AI Node (QBX) software platform" and the training section describes training segmentation algorithms on a dataset.
No.
The device is image post-processing software intended to assist in the interpretation of prostate MR studies and does not directly provide therapy or treatment.
Yes
The "Intended Use / Indications for Use" states that the software "may assist in the interpretation of prostate MR studies" and facilitates "analysis and study review." It also mentions "PI-RADS scoring," which is used in prostate cancer diagnosis. Although it clarifies that "Diagnosis should not be made solely based on the analysis performed using Quantib Prostate," its role in assisting interpretation and providing analytical tools for potential lesions points to a diagnostic adjunctive function.
Yes
The device is described as "image post-processing software" and an "extension to the Quantib AI Node (QBX) software platform." The description focuses entirely on software modules and their functionalities for analyzing MRI images. There is no mention of any accompanying hardware components or hardware-specific verification/validation.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze biological samples: IVDs are designed to examine specimens taken from the human body, such as blood, urine, tissue, etc., to provide information about a person's health.
- This device analyzes medical images: Quantib Prostate processes and analyzes MRI images of the prostate. It does not interact with or analyze biological samples.
- The intended use is image post-processing and analysis: The description clearly states the software provides "processing, visualization, and editing of prostate MRI images" and facilitates "analysis and study review of MR data sets."
While the software provides information that assists in clinical interpretation and potentially diagnosis, it does so by analyzing imaging data, not biological samples. This places it outside the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
Quantib Prostate is image post-processing software that provides the user with processing, visualization, and editing of prostate MRI images. The software facilitates the analysis and study review of MR data sets and provides additional mathematical and/or statistical analysis. The resulting analysis can be displayed in a variety of formats, including images overlaid onto source MRI images.
Quantib Prostate functionality includes registered multiparametric-MRI viewing, with the option to view images combined into a single image to support visualization. The software can be used for semi-automatic segmentation of anatomical structures and provides volume computations, together with tools for manual editing. PI-RADS scoring is possible using a structured workflow.
Quantib Prostate is intended to be used by trained medical professionals and provides information that, in a clinical setting, may assist in the interpretation of prostate MR studies. Diagnosis should not be made solely based on the analysis performed using Quantib Prostate.

Device Description
Quantib Prostate (QPR) is an extension to the Quantib AI Node (QBX) software platform that enables analysis of prostate MRI scans. QPR makes use of QBX functionality, and includes 3 specific QPR modules.
The three specific modules of QPR are as follows:
- An automatic processing module that performs input checks, prostate (sub-region) . segmentation, multi-parametric MRI (mpMRI) image registration, computation of a biparametric combination image, and optionally crops the images around the prostate.
- A two-step user-interaction module in which the user can: .
- edit the computed prostate segmentation (QBX functionality) and determine o PSA density (QPR-specific functionality).
- view multi-parametric MRI images (QBX functionality), and segment (QBX o functionality) and analyze potential lesions (QPR-specific functionality). This extension also shows the prostatic sub-region segmentation and biparametric combination image overlay. (QPR-specific functionality).
- . An automatic processing module that collects all results, and creates the report and DICOM output so that they can be exported back to the user.

Description of the training set, sample size, data source, and annotation protocol
The prostate and sub-region segmentation algorithms have been improved by updating the methodology and training it on over 400 scans.
Description of the test set, sample size, data source, and annotation protocol
Bench testing of the software was done to show that the system is suitable for its intended use and to evaluate the stand-alone performance of the sub-region segmentation algorithm. This was done by comparing the automatic segmentations to their ground truth and calculating the Dice overlap and Mean Surface Distance. To place the agreement between the automatic method and the manual segmentation into context, the results are compared with the interobserver measurements using statistical tests. Bench testing did not reveal any issues with the system, demonstrating that the modified device is as safe and effective as the predicate device.
With the results from the non-clinical performance testing of the prostate segmentation algorithm being at least as accurate as that of the predicate device, the semi-automatic clinical performance test of the prostate segmentation has not been repeated. The clinical performance test of the subregion segmentation and the ROI localization initiation as seen by the user in a clinical context is conducted in a qualitative manner. Radiologists were asked to score the subregion segmentations and ROI initial localizations using a 5-point Likert scale. It is concluded that sub-regions and ROI localizations are judged at least as accurate as the predicate device was.

7.2 Performance Data
The following performance tests are done for the combined prostate- subregion segmentation algorithm:
Non-clinical performance testing
Bench testing of the software was done to show that the system is suitable for its intended use and to evaluate the stand-alone performance of the sub-region segmentation algorithm. This was done by comparing the automatic segmentations to their ground truth and calculating the Dice overlap and Mean Surface Distance. To place the agreement between the automatic method and the manual segmentation into context, the results are compared with the interobserver measurements using statistical tests. Bench testing did not reveal any issues with the system, demonstrating that the modified device is as safe and effective as the predicate device.
Clinical performance testing
With the results from the non-clinical performance testing of the prostate segmentation algorithm being at least as accurate as that of the predicate device, the semi-automatic clinical performance test of the prostate segmentation has not been repeated. The clinical performance test of the subregion segmentation and the ROI localization initiation as seen by the user in a clinical context is conducted in a qualitative manner. Radiologists were asked to score the subregion segmentations and ROI initial localizations using a 5-point Likert scale. It is concluded that sub-regions and ROI localizations are judged at least as accurate as the predicate device was.
7.2.1 Safety implications
The changes made in Quantib Prostate 3.0 do not affect the safety of the device.
യ CONCLUSIONS
By virtue of its intended use, design features, and technological characteristics, Quantib Prostate 3.0 is substantially equivalent to a device that has been approved for marketing in the United States. The performance data shows that Quantib Prostate 3.0 is as safe and effective as the predicate device.
