Analog Discovery 2 Chart
Telling Analog Time. Telling Time Worksheets are a great way to practice reading a clock or watch face. On most of these worksheets, grade school students will be presented with a clock fact they either need to read to tell time or that they need to color in the hands to reflect a given digital time.
WaveForms is the user interface for the Analog Discovery 2. It is a custom toolset that allows users access to the full functionality of the Analog Discovery 2. Compatible with Mac, Windows and Linux, it provides any engineer with a portable oscilloscope, waveform generator, power supplies, data logger, logic analyzer, pattern generator, static I/O, network analyzer, spectrum analyzer, and script editor. It is the same software interface that is used with the Digital Discovery and Electronics Explorer boards. If your Analog Discovery 2 isn't detected there are several steps you can follow to troubleshoot:.Make sure the cable you are using is the cable provided with the Analog Discovery 2 and can provide enough power and data.Make sure that the Digilent FTDI driver was installed.If you are on Mac OS, try disconnecting your Analog Discovery 2 and restarting the Mac.Check out on troubleshooting.Post on the.If you are on OS-X 10.14 Mojave or later:.Delete the file DigilentFtdiDriver.kext.Disconnect the device.Restart OS-X.Reconnect the device.Start WaveForms. The device should now be detected.If the device is still not detected, please contact Digilent support.

Objectives: Positron Emission Tomography/Computed Tomography (PET/CT) scanners have proven their role as multimodality medical imagingtools, and are now integrated into routine medical practice. General Electric (GE) Healthcare recently launched the new digitalDiscovery MI (DMI) and analog Discovery MI-Digital Ready (DMI-DR) whole body Time-of-Flight (TOF) PET systems.
Discovery MIis the latest generation of PET/CT scanners commercialized and the first digital PET/CT system developed by the company. TheDMI-DR is ready to receive the digital detectors of the DMI. In 2018, Hadassah Medical Center received and installed thesetwo systems. This work compares the physical performance of the digital Discovery MI (DMI) and analog Discovery MI-DR (DMI-DR)PET/CT systems at one clinical site, and DMI at two other sites. Results: DMI spatial resolution at 1 cm radial-offset in the radial, tangential and axial positions was 4.62, 4.18 and 4.57 mm, respectively;for the system, DMI-DR spatial resolution was 4.58, 3.32, and 5.31 mm.
Measured sensitivity was 13.3 kcps/MBq at the centerof the FOV and 13.4 kcps/MBq 10 cm off-center for the SiPM based DMI system. DMI-DR system sensitivity was 6.3 kcps/MBq atthe center of the FOV and 6.8 kcps/MBq at 10 cm off-center. DMI measured noise equivalent count rate peak was 175.6 kcps at20.1 kBq/ml; DMI-DR was 146.7 kcps at 31.7 kBq/ml. Scatter fraction was 40.5% and 36.6%, respectively. DMI image contrastrecovery (CR) values (sphere-to-background ratio=4:1) were 73.2% (10 mm sphere) to 91.0% (37 mm sphere); DMI-DR, values rangedfrom 68.4% to 91.4%. DMI background variability (BV) was 1.8%-6.5%; DMI-DR was 2.3%-9.1%.

The Q.Clear algorithm improved imagequality, increasing CR and decreasing BV with both systems. Image quality results obtained using different image reconstructionalgorithms will be presented during the conference.
