Fully automated framework for the analysis of myocardial first-pass perfusion MR images Med Phys. 2014 Oct;41(10):102305. Doi: 10.1118/1.4893531. Authors Garth M Beache 1, Fahmi Khalifa 2, Ayman El-Baz 3, Georgy Gimel'farb 4 Affiliations 1 Department of Radiology. First-pass contrast-enhanced MR images of the heart were obtained at rest and during stress using a 1.5 T MR imager (Magnetom Vision, Siemens). The maximum slew rate was 40 T/m/sec and the maximal gradient strength was 25 mT/m. MR image acquisitions were gated to the ECG. Purpose: The presence of subendocardial dark-rim artifact (DRA) remains an ongoing challenge in first-pass perfusion (FPP) cardiac magnetic resonance imaging (MRI). We propose a free-breathing FPP imaging scheme with Cartesian sampling that is optimized to minimize the DRA and readily enables near-instantaneous image reconstruction.
To evaluate a left ventricular image registration algorithm for first‐pass MR myocardial perfusion. Materials and Methods. A normalized mutual information based motion correction algorithm was proposed and tested on 27 adenosine stressed myocardial perfusion cases consisting of pretreatment and posttreatment of 15 patients undergone autologous bone marrow mononuclear cell.
D800 is here. No more a mini D* but its own class. It seems both Canon and Nikon are aping each other. One gave up the huge megapixel race and another started it all over again. Hopefully it will be worth it :-)

January 4, 2012 - Deleting images
Some users have commented that FirstPass does not have the functionality to delete images after download. This option was not added to FirstPass by choice for the reason described here.
All cameras use the FAT file system to store images. This file system maintains two lists to figure out where each of the image files is located – a list directory entries and a list of clusters (storage spaces on media) being used by the file. When you delete a file, either on the camera or on a computer, only the directory entry is modified, while the cluster chain is left as is. This means that the space that used to be occupied by the deleted image is now left as an “empty hole” in the storage device. Once all the otherwise free space is used, the camera has to do lot more work to reclaim the space from the deleted files, which substantially slows down the response time of the camera.
Because of this reason, I strongly recommend to format the card in the camera after every download. Unlike deletion of files, which leaves the file system fragmented, formatting zeroes all the cluster chains and therefore the camera will have to do much less work to look for free space.
January 3, 2012 - happy new year
Wishing everyone a very happy and prosperous new year.

First pass yield (FPY), also known as throughput yield (TPY), is defined as the number of units coming out of a process divided by the number of units going into that process over a specified period of time.[1][2][3]
Example[edit]
Consider the following:
You have a process that is divided into four sub-processes: A, B, C and D. Assume that you have 100 units entering process A. To calculate first time yield (FTY) you would:
- Calculate the yield (number out of step/number into step) of each step.
- Multiply these together.
For example:
(# units leaving the process as good parts) / (# units put into the process) = FTY
- 100 units enter A and 90 leave as good parts. The FTY for process A is 90/100 = 0.9000
- 90 units go into B and 80 leave as good parts. The FTY for process B is 80/90 = 0.8889
- 80 units go into C and 75 leave as good parts. The FTY for C is 75/80 = 0.9375
- 75 units go into D and 70 leave as good parts. The FTY for D is 70/75 = 0.9333
The total first time yield is equal to FTYofA * FTYofB * FTYofC * FTYofD or 0.9000 * 0.8889 * 0.9375 * 0.9333 = 0.7000.
You can also get the total process yield for the entire process by simply dividing the number of good units produced by the number going into the start of the process. In this case, 70/100 = 0.70 or 70% yield.
The same example using first pass yield (FPY) would take into account rework:
(# units leaving process A as good parts with no rework) / (# units put into the process)
- 100 units enter process A, 5 were reworked, and 90 leave as good parts. The FPY for process A is (90-5)/100 = 85/100 = 0.8500
- 90 units go into process B, 0 are reworked, and 80 leave as good parts. The FPY for process B is (80-0)/90 = 80/90 = 0.8889
- 80 units go into process C, 10 are reworked, and 75 leave as good parts. The FPY for process C is (75-10)/80 = 65/80 = 0.8125
- 75 units go into process D, 8 are reworked, and 70 leave as good parts. The FPY for process D is (70-8)/75 = 62/75 = 0.8267
First pass yield is only used for an individual sub-process. Multiplying the set of processes would give you Rolling throughput yield (RTY). RTY is equal to FPYofA * FPYofB * FPYofC * FPYofD = 0.8500 * 0.8889 * 0.8125 * 0.8267 = 0.5075
Notice that the number of units going into each next process does not change from the original example, as that number of good units did, indeed, enter the next process. Yet the number of FPY units of each process counts only those that made it through the process as good parts that needed no rework to be good parts. The calculation of RTY, rolling throughput yield, shows how good the overall set of processes is at producing good overall output without having to rework units.
