Yes
The description mentions the software can be "trained (atlas creation)" and can be "delivered pre-trained with the comprehensive atlas or the end user can generate their own atlas," which is indicative of a machine learning approach, specifically atlas-based segmentation which often utilizes ML techniques.
No
The device is a software tool designed to assist clinicians in contouring the prostate gland in medical images. It does not directly treat or diagnose a medical condition. It is a tool for aiding in diagnosis, treatment planning, and monitoring, but the final decision on diagnosis and treatment is made by the clinician.
No
The device is described as "a standalone software application for Windows platforms that assists clinicians in generating estimates of the anatomy boundary contours of the prostate gland... to aid in patient diagnosis, treatment planning and post-treatment monitoring." It assists in delineation but "The clinician retains the ultimate responsibility for making the pertinent diagnosis and patient management decisions." The software itself does not make a diagnosis.
Yes
The device is explicitly described as a "standalone software application for Windows platforms" and a "standalone atlas-based segmentation software tool," with no mention of accompanying hardware components required for its primary function.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Segasist P-AC's Function: Segasist P-AC is a software application that processes medical images (CT, MR, ultrasound) to assist clinicians in contouring anatomical structures (the prostate gland). It does not analyze biological samples from the patient's body.
- Intended Use: The intended use clearly states that the software assists clinicians in generating estimates of anatomy boundary contours to aid in patient diagnosis, treatment planning, and post-treatment monitoring. This is image processing and analysis, not in vitro testing.
- Device Description: The device description reinforces that it's an atlas-based segmentation software tool for auto-contouring from different input image modalities.
Therefore, Segasist P-AC falls under the category of medical image processing software, not in vitro diagnostics.
No
The letter does not explicitly state that the FDA has reviewed and approved or cleared a PCCP for this specific device. The relevant text section indicates "Not Found" for PCCP authorization.
Intended Use / Indications for Use
Segasist P-AC contouring software is a standalone software application for Windows platforms that assists clinicians in generating estimates of the anatomy boundary contours of the prostate gland in Computed Tomography (CT) scans, Magnetic Resonance (MR) images and ultrasound (sonography) scans to aid in patient diagnosis, treatment-planning and post-treatment monitoring. The software is intended to be used to provide clinicians with tools to efficiently contour/delineate the prostate gland in volume data and save the results in DICOM and BMP format. The clinician has the ability to use the saved contours directly or import them in other software tools to perform the task at hand.
The clinician retains the ultimate responsibility for making the pertinent diagnosis and patient management decisions based on their standard practices and visual comparison of the individual images. The Segasist P-AC software tool is a compliment to manual contouring techniques.

Device Description
Segasist P-AC (Segmentation Assistant for Prostate – Auto-Contouring) is a standalone atlas-based segmentation software tool for auto-contouring of the prostate gland from different input image modalities (Computed Tomography (CT) scans, Magnetic Resonance (MR) images, ultrasound scans). The software can read, write and display DICOM images from/to local directories, and offers the possibility of defining regions of interest (ROls) around the prostate gland in order to delineate the prostate for contouring, visual assessment, and size and volume calculation purposes, either manually, or via semi-automated or automated processes.
The Segasist P-AC software is a tool that has been designed and developed to assist clinicians (radiologists, oncologists, medical physicists etc.) in performing contouring/delineation of the prostate gland in images in multiple modalities more efficiently. The software is capable of segmenting the prostate gland in individual slices, in a choice of different modalities, and for any given view (axial, sagittal, or coronal). This is done by requiring some user input (clicks or drawing ROIs).
For volume prostate data. Segasist P-AC calculates the prostate volume in cubic centimeters and displays the contours on each slice. The results (contours) can be saved as DICOM or binary images (BMP), which can be edited/modified at any time, completely dismissed or accepted and saved by the end user.
The efficiency of contouring performed by the Segasist P-AC software may be improved by generating/using an advanced atlas using gold standard images created by the experienced clinician(s). This requires the software to be trained (atlas creation) before being used. The software can be delivered pre-trained with the comprehensive atlas or the end user can generate their own atlas; a well-established practice for atlas-based segmentation software products.
Segasist P-AC also offers a built-in editor, enabling the user to edit, modify, or change the extracted prostate boundaries to their desired configuration based on their medical and clinical knowledge and experience. The results provided by the Segasist P-AC software needs to be approved by the experienced clinician and can always be modified or corrected by him/her. In addition, the end user can delineate the prostate gland manually using the P-AC software, if necessary or desired. As a result, when Segasist P-AC generates a result, the expert user always has the final decision to override the software result, if deemed appropriate in his/her clinical judgment. It is up to the expert user to accept the result without any change, reject it completely and delineate manually, or modify the Segasist P-AC result and then save it. The software does not provide any auto-detection or auto-saving functionalities. Regardless of the accuracy of Segasist P-AC result. it is always the experienced clinician that remains the decision maker regarding the acceptability of the computed segmentation. Therefore, the final decision on diagnosis, treatment and overall management of the patient is not based on the software result.
Segasist P-AC software does not alter the original input images of the prostate gland. nor does it change the final results obtained once approved by the clinical expert.
Segasist P-AC offers several features and functionalities such as, but not limited to:
- . Import/Export DICOM images
- . Saving Contours to DICOM or BMB format
- . Semi-automated Segmentation
- . Auto-Segmentation (fast slice-to-slice auto-segmentation with minimal user interactions)
- . Volume Segmentation and measurement
- . Edge Enhancement (contour enhancement by user controlled edge snapping).
- . Standard Functionalities for Image Visualization (windowing, contrast, brightness, zoom, panning etc)
- . Advanced Functionalities for Contour Editing For Manual Segmentation (drawing, inflating, deflating, shifting, cut & add etc)
- . User access to modify the resulting contours at any time

The clinician retains the ultimate responsibility for making the pertinent diagnosis and patient management decisions based on their standard practices and visual comparison of the individual images. The Segasist P-AC software tool is a compliment to manual contouring techniques.
Testing:
The Segasist P-AC software was designed and developed with the input and collaboration of experienced and trained professionals, such as radiologists, oncologists or other highly qualified medical clinicians that are proficient in reading, evaluating and interpreting images of the prostate produced by MR, CT or ultrasound devices. The input was captured in a written and approved Software Requirement Specifications Document. The Segasist P-AC software has been developed in a manner consistent with accepted standards for software development, including both unit and system integration testing. Testing was conducted both internally at Segasist Technologies and independently by experienced and trained medical professionals who are representative of the commercial end users of the software using clinical test cases. No clinical testing was conducted to demonstrate safety or effectiveness as device bench testing was completed using imported images from the various imaging modalities of the prostate in sufficient numbers to support the intended use of the device. This bench testing deemed that the

Segasist P-AC software works as intended, was acceptable for clinical use, and did not introduce any new concerns of safety or effectiveness compared to predicate products or manual contouring of the prostate gland.
As noted, imported prostate image datasets from the various imaging modalities were used as input for testing of the software functionalities in accordance with the software validation/verification plans. A full description of the software functionality, device hazard analysis, software requirements, and verification and validation testing can be found in Section 18 - Software, of this submission.
The device has no patient contacting materials and is utilized only by trained professionals. The output of the device is evaluated by professionals skilled in reading, evaluating and interpreting images of the prostate gland produced by CT, MR or ultrasound, which allows sufficient review for identification and intervention in the event of a malfunction. Device output and analysis is not real-time with respect to patient involvement or presence, and is only used to aid the end user in the further evaluation of the available prostate imaging data. Additional clinically relevant parameters / tests, including data from alternative imaging modalities, must be used in addition to the output of the Segasist P-AC software, in the diagnosis, treatment planning and on-going management of the patient. The device does not impact the quality or status of the original acquired imaging data.
Conclusions:
The Segasist P-AC contouring software has the same intended use and similar technological characteristics as the previously noted predicate software devices. As demonstrated within this Traditional Premarket Notification, there are no substantial differences between the Segasist P-AC contouring software and the stated predicate devices, and therefore, the Segasist P-AC software does not introduce any new concerns related to safety or effectiveness. The data contained within this Premarket Notification 510(k) submission is sufficient to deem the Segasist P-AC software substantially equivalent to those predicates described within this application.
