 ===== User Profile =====
-The Astroid Planning App is a tool to develop radiotherapy treatment plans for delivery using a proton therapy system. Such plans are generally developed to meet the directives of a physician through a formal documented prescription. As such, the users of this application are expected to be supervised by an attending physician and should themselves be experienced in the physics and dosimetric characteristics of proton radiotherapy. Additionally, users are expected to have formal training in general radiotherapy techniques and best practices, proton therapy specific planning techniques, and general principles of patient safety and care. Most users will have college-level training or degrees, as well as licensure for their particular roles and responsibilities through their state, nation, or professional association. Users should also be well versed in regulations regarding protection of patient health information and have a basic understanding of standard practices regarding computer usage and security.
+The decimal3D should be used the guidance of a physician by authorized users such as physicists, certified medical dosimetrists, radiations therapists, radiologic technologists, nurses and those who have been trained by the .decimal staff or by the clinical staff.
 ===== Product Features =====
-In the most common, primary use case of the software, users will import patient data from existing imaging and contouring software programs, manage physician prescription and intent information, develop a proton treatment plan, and analyze the plan to determine how well it meets the physician’s goals. Since the critical treatment planning functions and calculations are handled outside this software application, by a software of known quality and pedigree, the primary and most frequently used functions of this software are the record keeping service (for patient data storage via Thinknode®), user interface controls, and visualization tools.
+decimal3D will handle patient data entry. The user will be able to take a three dimensional scan of the area where the physician has outlined the area to be treated. This scan will be in full color and dimensonally accurate. From this the user can digitize the treatment area, design the electron aperture as well as place the beam. The decimal3D App also allows the user to order the aperture through and interface with the decimal Direct API.
- The Astroid Planning App software communicates with other treatment planning systems generally by sending & receiving files in various DICOM RT formats, although the extensive Application Programming Interface (API) of Thinknode® allows users to easily build their own export and import conversion applications. Since the accuracy of information computed and displayed by an application such as this is very important to the proper treatment of patients, it is critical that users have the appropriate educational and clinical experience backgrounds to adequately understand and use the product. Additionally, since each radiotherapy treatment machine produces a unique beam of radiation, there is much responsibility on the end users to adequately commission and test this software over the full range of expected treatment conditions before the system is utilized for patient treatment. It is this area that provides opportunity for the most likely incorrect use of the software, which would be poor or inadequate commissioning of the application (note many other cases of potential misuse have be designed out of the system by limiting allowed user interactions, providing warnings, and preventing unsafe or incompatible operations). This main misuse is mitigated by requiring that users understand that it is their responsibility to perform appropriate quality assurance measurements for every patient plan prior to treatment, which should independently confirm that the treatment plan information displayed within the Astroid Planning App adequately matches the actual, to be delivered, plan. Please note that such testing is a safety and regulatory requirement in most territories.
 ==== System Availability and Data Integrity ====
-As with any cloud based application there is always concern with system availability and uptime. Astroid makes use of caching at various system levels to improve performance and mitigate some of these concerns, however, this can never provide 100% assurance and reliability. Since customer has unique needs, specific business agreements will be entered into with each customer as appropriate to detail the reliability guarantees and assurances. Data integrity is generally a less variable concern, as Astroid's cloud storage providers strong guarantee the highest commercially available data redundancy and integrity limits (approaching 99.999999% per year). Data is transferred to and from the cloud services using secure transfer protocols, that guarantee error-free of transfer using common industry standard techniques (for more details please see the [[https://developers.thinknode.com/guides/ipc|Thinknode IPC article]]). While Astroid has been designed with security in mind, users should understand that it is still their responsibility to ensure the system is accessed and controlled properly. Following international standards for IT risk management, such as IEC 80001-1, is therefore highly recommended.
+FIXME - We need to discuss this
-Since data integrity is such a critical feature for application such as this, the Astroid Planning App automatically saves both the state of the application and the working record data on a timer (triggering every minute or less) as well as on exit of any create or edit event in the application. Additionally, each "save" event creates a new entry in the record's history log in Thinknode, which provides a log file for editing of all records and a ensures that patient records are saved securely on an independent medium so they are not lost in the event of a local system failure or crash.
 ==== Coordinates and Units of Measure ====
-The following is a list of several important items that users should understand in regards to the information displays in the Astroid Planning Application:
+FIXME- should we delete this for the first go round?
-  * The Astroid Planning exclusively uses DICOM coordinate systems for display information (machine based coordinates are NOT available)
-  * All linear dimensions are shown in millimeters (mm)
-  * All angular dimensions are shown in degrees (deg)
-  * All radiation dose quantities will be shown with their corresponding units within the application (e.g. Gy(RBE) or %)
-  * All date/time values are provided in a // dd/mm/yyyy h:m:s // format using local time on a 24 hour clock
-  * All date and time notifications in Astroid should match current Windows OS date and time, including proper use of daylight savings time where appropriate (note: Astroid will display in 24 hour format, while Windows may display in am/pm depending on local settings)

 ==== Data Displays and Interpretation ====
-Astroid contains many displays throughout the plan creation process. Please refer to [[http://apps.dotdecimal.com/doku.php?id=planning:userguide:tutorials:all_tutorials#astroid_optimization|the Astroid Tutorials]].
