Clinical evaluation of electron radiography. Current status.
Details of a 4-phase evaluation of electron radiography are reported. The experimental equipment now uses liquid toners which result in less edge contrast and latitude than in powder-cloud exposures. Use of a bias technique during development prevents deposition except to areas where voltage exceeds the bias voltage. Quality radiographs with decreased doses and expense result.
