Questions related to Breast Imaging
Breast cancer is the most commonly diagnosed and leading cause of cancer deaths among women. ‘‘Camelyon Grand Challenge (Camelyon 2016)’’ is a task to evaluate computational systems for the automated detection of metastatic breast cancer in WSIs of sentinel lymph node biopsies. Is there any updated newly published dataset?
I hope you are doing well.
I am working with imaging systems. I am confused about the effects of linear polarizer in such systems ( I mean how a linear polarizer can improve the resolution?) and why working with one polarization is better than two polarization in image processing systems?
A detailed study of medical image registration technique with application and validation. I am looking for suggestion to select a >1.4 impact factored and relatively fast review journal to send my manuscript.
In the development of a Co-registration method to compare two 3D MRI exams (before and post chemotherapy treatment for one patient using the same MRI modality) ==>you can see the problematic on the image uploaded enclose<==. The results show a correct alignment at the visual level. However, this is surely not enough. The first thing I have to think about is to validate the findings by comparing the anatomical points of interest (Landmarks). Are there any more practical propositions?
I thank the community in advance.
I am working on Breast Image Segmentation on MRI and Suspicious regions detection on Mammograms, to make my work complete I need to compare the algorithm I propose with some state of the art methods by using a publicly available ground truth.
How to calculate normal components of the propagation constant
Is there an online database to decrease unnecessary breast biopsies according to suspicious mammogram results to detect breast cancer. Database should include breast imaging reports, biopsy reports, and clinical notes.
Thanks in advance,
Can any one suggest which feature extraction method is suggestible for differentiating Benign and Malignant in Digital mammogram Images?
And some research papers based on this topic?
The BI-RADS score is measured after getting the image of mammography, are these scores common for ultrasound, MRi, PET scan and CT scan?
Any RCTs? In assessing the success of per-cutaneous needle aspiration for breast abscesses, part of exclusion criteria has been size (larger than 3cm or 5cm diameter according to different authors). Is there anyone with information about which of the two is a superior predictor of failed needle aspiration?
The question is addressed to people, who use methodology described in the "European Guidelines 4th Edition" to calculate average glandular dose.
The dose is calculated as K*g*c*s, where 'K' stands for kerma, and g/c/s are factors dependent on characteristics of breast and beam quality. Now an example: 50 mm of PMMA is equivalent to 60 mm of typical breast (there are some assumptions on breast composition behind it). We can assume, that the exposure will be made at the same conditions for 50 mm of PMMA and for 60 mm of breast (let's forget about spacers for a while). In both cases we have e.g. Mo/Rh, 30 kV, 100 mAs, so in both cases kerma at some specified point will be identical. G/c/s factors are the same for "typical breast simulated with 5.0 cm PMMA" and for "6.0 cm breast", thus the only will be in 'K':
a) typical breasts simulated with PMMA: in that case 'K' is kerma "at the upper surface of the PMMA";
b) clinical breast doses: 'K' is kerma "at the upper surface of the breast", closer to the source than in case (a)
Because of that difference, the 'clinical' dose will be slightly higher than the 'phantom' dose. Is there any good reason for that?
I am going to assess the patients discomfort while performing ROLL and compare it to wire guided localisation.
