  • Patent number: 9666219
    Abstract: Determining quality metrics of a magnetic tape recording medium. A production module that includes a write element that writes magnetic transitions to the magnetic tape is substantially in constant physical engagement with the magnetic tape. A supplemental module that includes one or more read elements periodically physically engages the magnetic tape, and the read elements generate an electrical signal corresponding to transitions written to the magnetic recording medium by a write element. A computer receives information representative of the electrical signal and determines if a quality metric of the magnetic recording medium derived from the electrical signal is within a defined range. If the quality metric is not within the defined range, a defined action is performed by the computer.

  • Publication number: 20160187443
    Abstract: In a method for acquiring MR diffusion data, in a control computer of an MRI system, multiple individual data sets, respectively corresponding to multiple diffusion models, are defined and combined to form a combined data set. Each of said individual data sets is comprised of multiple diffusion image individual data subsets that are to be acquired on one or more specific shells, respectively, and in one or more gradient directions, respectively. Different specific shells among the multiple shells have different diffusion factors. The control computer then operates the MRI system, namely the data acquisition scanner thereof, in order to acquire MR data corresponding to the defined combined data set.

  • Publication number: 20160073980
    Abstract: An imaging apparatus and a positioning apparatus that include an imaging unit for imaging a detected part of a body to be detected; and a distance positioning unit having at least two signal positioning devices, i.e., a signal generator and a signal detector, wherein one signal positioning device is arranged at the detected part, the other signal positioning device is arranged at a position where a predetermined position relationship exists relative to the imaging unit. The position of the detected part in at least one direction in a three-dimensional space relative to the imaging unit is obtained according to a measured distance between the two signal positioning devices. The imaging apparatus and the positioning apparatus reduce pre-positioning imaging sequence workload, and the risk of radiation on the body to be detected is avoided.
