Odds ratio for ordinal variables from PROC GENMOD

给你一囗甜甜゛ 提交于 2019-12-24 06:03:32
问题 I have a set of data where I am creating a logistic regression model, looking at the odds of a binary outcome variable (Therapy), with Stage as an ordinal explanatory variable (0,1,2,3,4). A1c is a continuous variable. Because each patient has two eyes, I must use the repeated subject = patientID(EyeID) statement. The following is my code: PROC GENMOD data=new descend; class patientID EyeID Stage (param = ordinal) Therapy (ref ="0") Gender(ref="M") Ethnic agegroup/ PARAM=ref; model Therapy =

Storage Commitment Service (push model): how i get the result back to my SCU?

半腔热情 提交于 2019-12-22 18:36:19
问题 I planned to implement a Storage Commitment Service to verify if files previously sent to the storage were safely stored. My architecture is very simple and straightforward my SCU sends some secondary capture images to the storage and I want to be sure they are safely stored before delete them. I am going to adopt push model and I wonder what steps/features I need to implement to accomplish the service What I understood is I need to issue a N-ACTION request with SOP Class UID 1.2.840.10008.1

I'm looking for some OS java engines for medical diseases diagnose . these are engines that takes queries input from user discribing patient symptoms and the engine should return suggestions of potential disease according to input symptoms. does such engines exists somewhere? I prefer some Java OS engine in this

Has Boost ever been used in a regulated project (FDA, FAA)?

不问归期 提交于 2019-12-21 07:03:09
问题 While posting a comment recently, I found myself remarking that, in my experience, Boost is not widely used in regulated industries (FDA, FAA). In fact, I don't know of any project that uses it or has used it. I realize, though, that my experience may be lacking here, so I wanted to know if anybody had knowledge of a project using boost in a medical device or in an aviation flight system (lighting, cabin controls, cockpit equipment, etc.). I am not sure this is the right place to ask it

Best Way to Segment Lung Nodules in Matlab

こ雲淡風輕ζ 提交于 2019-12-21 06:26:27
问题 I am working with images processing in Matlab. I am trying to segment out only malignant (cancerous) lung nodules. Initially I managed to segment out Lung and all possible nodules. I have used following Matlab code: segM = % Segmented Lung % Segment nodules BW = im2bw(segM, 0.55); Now, I want to apply some filter that will filter all benign (noncancerous) nodules. I am looking for solution from long time but I haven’t found any way to continue it. Here is the segmented Lung: Update: Consider

How is openEHR supposed to be used?

二次信任 提交于 2019-12-21 04:03:00
问题 I am researching about electronic health records (EHR). OpenEHR seems to be quite extended and appreciated in this field, as it is widely adopted. However, I fail to find how it is used. I mean, I can see all the definitions for archetypes, and how those definitions are written in ADL or XML. But, once I have an archetype which is just that, a definition of a certain data model, how do I use that? Is there another type of representation, maybe also in ADL or XML? Are there any examples of

Best practices for keeping the web server data protected

▼魔方 西西 提交于 2019-12-20 09:42:50
问题 Lets say I run a medical facility and want a website where my users/patients can lookup their private records . What would be the best solution against most-common attacks? Even if I use a private server bought somewhere, and rely on its monitoring services there's a good chance someone could find a security hole and steal my data. End of my business. What are the best practices for such architecture? 回答1: First you need to identify the attacks that you want to try and protect against, and

How are the spacing value of the z dimension and thickness (0018, 0050) different in dicom series?

懵懂的女人 提交于 2019-12-19 10:20:18
问题 I've been studying some dicom series and find that the thickness attribute and the itkimage.GetSpacing()[2] value are not always consistent. For example the thickness (0018, 0050) value encoded in the dcm file is 1.5 mm but the corresponding spacing indicated simpleITK on z axis is 1.00 . Then what value should I use to indicate the physical distance between adjacent voxel center s on the z axis? If they are different things then What do spacings actually mean? I retrieve thickness and

Read img medical image without header in matlab

喜夏-厌秋 提交于 2019-12-19 05:04:58
问题 I have a radiograph .img file without the header file. However, the researchers who have published the file have given this information about it High resolution (2048 x 2048 matrix size, 0.175mm pixel size) Wide density range (12bit, 4096 gray scale) Universal image format (no header, big-endian raw data) Using this information, I tried fread command in Matlab to read the image into Matlab. fid = fopen('image.img','r','B'); oneSlice = fread(fid, [2048 2048], '*uint8','B'); imshow(oneSlice)
