13.3 MEDICAL TRICORDER13.3.1 Medical tricorder and scanner peripheral13.3 MEDICAL TRICORDERThe medical tricorder (MT) consists of a standard tricorder,to which is added a specialized medical peripheral(MP) device. This peripheral, one of a number of dedicatedauxiliary computing options available to Starfleet crews, addsmany powerful sensor and analysis functions to those used bysickbay personnel aboard the ship.The MP comprises two components, the computingsection and deployable high-resolution sensor. The MPworks with the standard tricorder user interface to access allof the normal and added functions, in both shipboard and fieldoperations. It measures 8.5 x 3.0 x 3.0 cm and masses 80 g,bringing the total tricorder length to 15 cm, and mass to 430g. As with the standard tricorder, the case is constructed of micromilledduranium foam. The major components include anauxiliary sarium krellide power cell, sensor assemblies, peripheralprocessing block, and memory storage units. Poweris not tapped from the main supply in the standard tricorderunless required, and cells in both sections can be rechargedthrough the standard tricorder induction circuit. Total operationtime is eighteen hours.The peripheral sensors encompass 86 electromagneticdevices mounted about the internal frame, upper and sidepanels of the casing, and the forward section of the handsensor receptacle. Each maintains an FOV lower limit of 1/4degree. None are omnidirectional, but specialized for focusedmedical readings. The hand sensor incorporatesfifteen high-resolution devices for readings down to thirtyseconds of arc. Active and passive scans provide detaileddiagnostic readings of total body mechanical processes,organ system function, disease organism infiltration, andbody electromagnetic conditions. Combined readings cansynthesize images and numerical readouts to aid sickbaypersonnel in identifying biological antagonists and determiningcourses of treatment.The MPcomputercapabilities are contained in the medicaldatabase comparator/analysis subsection (MDC/AS) attachedto 101 sensors. The MDC/AS manages incoming data,prioritizes processing tasks, routes processed data, andmanages control and power systems. It is rated at 1.5 x 10 10calculations per second. In the field the database sectiondraws upon an updatable file of known medical conditions formost humanoid types and 217 DNA-based nonhumanoids.When operating aboard ship, the MP can draw upon the entiremedical database of the USS Enterprise as well as the filesallocated to other disciplines.A wide selection of tomographic and micrographic scansare included in the default device settings. The functioncontrols of the standard tricorder may be used to configurecustom scan modes for the case-mounted and hand sensors,with menu choices visible on the main display screen.
