The summary describes a software device that uses optical scanning and user input to design radiation therapy devices. It explicitly states that it does not use internal imaging technology and focuses on digitizing a pre-drawn area. There is no mention of AI, ML, or any related concepts in the device description, intended use, or performance studies.
No.
The device's purpose is to improve the efficiency of designing patient-specific radiation therapy beam-shaping block devices, not to directly treat or diagnose a disease. It is a tool for designing a therapeutic device, not a therapeutic device itself.
No
The device's purpose is to improve the efficiency of designing patient-specific radiation therapy beam-shaping block devices by digitizing a pre-drawn treatment area. It explicitly states that it is "not intended to replace CT imaging or other internal imaging modalities" and that the radiation oncologist determines the treatment approach "independent of any information provided by this application." This indicates it processes existing clinical decisions rather than making new diagnoses or providing diagnostic information.
No
The device description explicitly states that it uses an "off-the-shelf depth sensing scanner" which is a hardware component. While the core functionality is software, the device relies on and integrates with this specific hardware for its primary function of capturing 3D models.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The intended use and device description clearly state that this device uses optical scanning technology to capture a 3D model of the patient's external treatment area. It does not involve the analysis of blood, tissue, or any other bodily fluid or substance.
- The purpose is to improve the efficiency of designing a physical device. The primary function is to create a digital model of the patient's external anatomy to facilitate the design and ordering of a patient-specific radiation therapy beam-shaping block. This is a design and manufacturing process, not a diagnostic test performed on a biological sample.
- The device replaces a physical template and 2D scanning process. The description explicitly states that it replaces a process involving a clear plastic template placed in the treatment machine and a flatbed document scanner. This further reinforces that the device is focused on capturing external anatomical information for design purposes, not analyzing biological samples.
Therefore, while this device is used in a clinical setting for patient treatment planning, its function does not align with the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The primary purpose and intended use of this device is to improve the efficiency of designing patient specific radiation therapy beam-shaping block devices through the use of optical scanning technology. This device will serve as a direct replacement to the current processes for designing such radiotherapy devices in cases where a "clinical patient set up" is used (i.e. cases where the treatment field is determined by direct physician examination, not by internal imaging technology).
This product is not intended to replace CT imaging or other internal imaging modalities and should be used only in cases where a qualified radiation oncologist has made appropriate determination of the acceptability of a "clinical patient set up" approach, independent of any information provided by this application. In other words, the role of this product is to simply ensure efficient and accurate ordering of a patient-specific beam-shaping block device from our company, in cases where a licensed radiation oncologist has predetermined that such a device and treatment approach is appropriate for the patient at hand. Thus this device's indications for use include patients with a variety of cancer and disease conditions, which will be treated under the direct supervision and guidance of a radiation oncologist that has prescribed a desired dose of radiation to be delivered to the patient.

Device Description
This device is a software product with the primary purpose to improve the efficiency of designing patient specific radiotherapy treatment devices. It uses proven off-the-shelf optical scanning technology to replace portions of the current clinical treatment device design workflow to achieve this goal. Specifically, this device uses an off-the-shelf depth sensing scanner to accurately capture and construct a full color, 3D model of a patient's treatment area. This scanner captures dimensionally accurate depth information in realtime using a combination of a structured light field infrared projector and infrared camera, and is coupled with a color camera to provide precise, full color, 3D models of patients without exposing them to any harmful radiation.
Our decimal3D software is an iPad application that guides users through the process of capturing a scan of a patient. It then provides tools that allow users to digitize the treatment area, which is pre-drawn on the patient's skin by the radiation oncologist, on the 3D model. Users also specify other device parameters, such as their treatment machine type, applicator size, and treatment direction, which allows the decimal3D software to complete the design of their treatment device. Finally, our software allows them to view and order the device for fabrication by our company. This process is directly analogous to the current digitization process in the existing clinical workflow except the predicate software device requires the user to use a clear plastic template placed in the head of the actual treatment delivery machine to project the device shape to the patient's skin surface using a light field. This acrylic template is then scanned using a flatbed document scanner and the shape is digitized in 2D using the predicate software.

.decimal p.d K151369
Intended Use:
The primary purpose and intended use of this device is to improve the efficiency of designing patient specific radiotherapy devices. This device will serve as a direct replacement to the current processes for designing such patient-specific radiotherapy devices. One such common current process is for electron therapy clinical setups, which involves hand drawing of the patient-specific aperture shape onto a semi-transparent "template" block, using the treatment light field to verify accuracy against the treatment area that has been outlined directly on a patient by the treating physician. This now flattened and projected aperture shape can then be scanned and digitized allowing for computer controlled fabrication. This decimal3D device will replace this process by providing a means to accurately scan and digitize the treatment area. This device also provides a means for designing and ordering the required devices.
Indications for Use:
The primary purpose and intended use of this device is to improve the efficiency of designing patient specific radiation therapy beam-shaping block devices through the use of optical scanning technology.

This product is not intended to replace CT imaging or other internal imaging modalities and should be used only in cases where a qualified radiation oncologist has made appropriate determination of the acceptability of a "clinical patient set up" approach, independent of any information provided by this application. In other words, the role of this product is to simply ensure efficient and accurate ordering of a patient-specific beamshaping block device from our company, in cases where a licensed radiation oncologist has predetermined that such a device and treatment approach is appropriate for the patient at hand. Thus this device's indications for use include patients with a variety of cancer and disease conditions, which will be treated under the direct supervision and guidance of a radiation oncologist that has prescribed a desired dose of radiation to be delivered to the patient.
Summary of Technological Characteristics:
decimal3D technology is substantially equivalent to the listed predicate device p.d (K151369). decimal3D and p.d both provide tools to digitize physician outlined treatment fields into patient-specific devices to be used in radiotherapy treatment delivery. Both p.d and decimal3D include displays for visualizing the physician drawn shape and tools for digitizing this image into a two dimensional contour. Unlike p.d, decimal3D provides a mechanism to directly capture the physician drawn treatment area rather than importing this image from a separate system. However, this does not detract from the point that the features included in both software for creating the patient device are substantially equivalent in terms of technology, intended uses, and end user profiles.
Summary of Non-Clinical Testing:
Clinical testing was not performed as part of the development of this product. Clinical testing is not advantageous in demonstrating substantial equivalence or safety and effectiveness of the device since testing can be performed such that no human subjects are exposed to risk. Clinically oriented validation test cases were written and executed by .decimal personnel and hospital-based testing partners where this device was deemed safe and effective for clinical use. The tests show that this device performed as well as the predicate device and demonstrated that the quality of the resulting surface scans is sufficient to provide the accuracy needed to design patient specific beam shaping devices.
