DESCRIPTION:There is a continuing need for improved signal-to-noise\nratio
  in detection of magnetic resonance signals\, since this can\nincrease res
 olution both in MR imaging and in MR spectroscopy\, and\npotentially allow
  earlier detection or diagnosis of potentially lethal\ntumours. Small\, in
 ternal probes can increase SNR through a combination\nof closer coupling t
 o the signal source and reduced sensitivity to\nbody noise. However\, micr
 ofabrication techniques are required to\nrealise high-performance detector
 s at low cost and in clinically\nuseful formats. This talk will provide an
  overview of the design\nissues and present examples of two recently demon
 strated devices: a\nrigid needle-shaped detector designed for complete imm
 ersion in\nexcised tissue and a flexible catheter-mounted detector capable
  of\npassing the biopsy channel of an endoscope and into the biliary duct\
 nsystem.\n
