Radiation dosimetry in digital breast tomosynthesis: Report of AAPM Tomosynthesis Subcommittee Task Group 223 -
The radiation dose involved in any medical imaging modality that uses ionizing radiation needs to be well understood by the medical physics and clinical community. This is especially true of screening modalities. Digital breast tomosynthesis (DBT) has recently been introduced into the clinic and is being used for screening for breast cancer in the general population. Therefore, it is important that the medical physics community have the required information to be able to understand, estimate, and communicate the radiation dose levels involved in breast tomosynthesis imaging. For this purpose, the American Association of Physicists in Medicine Task Group 223 on Dosimetry in Tomosynthesis Imaging has prepared this report that discusses dosimetry in breast imaging in general, and describes a methodology and provides the data necessary to estimate mean breast glandular dose from a tomosynthesis acquisition. In an effort to maximize familiarity with the procedures and data provided in this Report, the methodology to perform the dose estimation in DBT is based as much as possible on that used in mammography dose estimation.

Father Devises A 'Bionic Pancreas' To Help Son With Diabetes -
Insulin monitors and pumps are getting better, but a person with diabetes will tell you they’re far from ideal. Potential solutions include one that delivers two hormones to control blood sugar.
Exciting work from Ed Damiano, Associate Professor of Biomedical Engineering at Boston University’s College of Engineering. The development of automated, wearable sensors that require minimal maintenance from the patient will undoubtedly be the next frontier of personalized medicine and advanced personal therapeutics.
The results of this most recent study were published in NEJM: http://www.nejm.org/doi/full/10.1056/NEJMoa1314474
The true origin of lead vests.
Pair this tech with a “smart fork" or tooth sensors and we’ll be on our way to measuring all of our food habits, which will provide some seriously awesome health data.
"Would you like to be able to look up the calorie content of the specific apple you’re eating? You could take it to a lab and run it through a spectrometer, but accurate spectrometers are huge, expensive machines that are often only owned by institutions and require training to use. A new startup, however, wants to make it easy as running an app and pairing a bluetooth dongle.
The SCiO is a handheld device that pairs with a smartphone through Bluetooth LE being developed by Consumer Physics, an Israel-based startup funded by Kholsa Ventures. It’s based on near-infrared spectroscopy, which means it reflects light onto an object, then collects and analyzes the light reflected back.”

Really interesting data, very impressive data visualization.
