The first value to look for on the specification sheet is maximum (or peak) gradient strength. Rise time is measured in milliseconds, and is typically in the range of 0.1-0.3 msec for most scanners.Rise time is meaningless by itself, because a scanner with very weak gradients might ramp up to full strength very quickly, but have overall poor gradient performance for imaging.aveat emptor: The typical gradient strengths and slew rates quoted above are per axis (i.e. values for the x-, y-and z-gradients individually). Some vendors, often those with somewhat inferior gradient performance, will instead quote effective gradient strengths and slew rates.
Why not add a photo booth? Thatâs what owner Evan Chen and general manager Kevin Inkles decided last fall. The Buzzy Booth cost $2,500, and was branded in TOA designs and logo. The free photos are digitally âframedâ in a TOA-created logo, and customers can opt to have them sent to their email or posted on their social media feed.
1 On average, renting a photo booth can range anywhere from $400 to $1,300 for two to four hours, with additional hours costing upwards of $100 per hour.2  For example, PartyBooths.com provide photo booth rentals for your event. They have different packages which start with the basic 2 to 4 hour rental that can cost $645 to $1,095. 2  They also offer double prints for the same number of hours; this package can cost $745 to $1,295. 3  WNCPhotoBooth.com is another company that provides photo booth rental services.
