Non – invasive Fetal Scalp pH Measurement Utilizing Magnetic Induction Spectroscopy Technique
Conventional fetal of fetal scalp sampling needs an invasive method to acquire blood sample to the fetus. In this paper describes a suggested non-invasive technique employing magnetic induction spectroscopy based on hydrogen conductivity in pH solution. Four types of transmitter-receiver (Tx-Rx) coil pairs are developed and test with frequency range from 2MHz to 10MHz. The phase reading from both reference channel, and sample channel is taken and the phase change is calculated from the differences between both channels. The result shows that the phase is decreased as the pH value of the solution increase. Circular pair of Tx-Rx shows a good sensitivity reading while square pair Tx-Rx shows a linearity result. From the result obtained, it is proved that single channel magnetic induction spectroscopy can be used as a non-invasive pH meter as an alternative to invasive pH meter
Jaundice assessement of newborn baby: a short review on Kramel’s Rule and magnetic induction spectroscopy
Jaundice is a yellow discolouration of white eyes (sclera), skin and mucous membrane which is clinically apparent when the level of serum bilirubin rises up to 5 mg/dl. Jaundice could cause abnormalities in the newborn infant when production of bilirubin exceeds the normal range. Formation of bilirubin starts from degradation of hemoglobin and haemoprotein, which is released from red blood cell. Current technique in evaluating jaundice of new born infant is based on Kramer’s Rule but unfortunately it is not very applicable to the babies with dark skin. Thus Magnetic Induction Spectroscopy (MIS) is introduced as an alternative to this issue as MIS is a non-invasive, non-intrusive and electrodeless measurement scheme. This paper will go through short overview on jaundice measurement as well as MIS modality
Simulation of single channel magnetic induction spectroscopy for fetal hypoxia detection
Conventional fetal scalp blood sampling (FBS) need an invasive measurement to detect fetal hypoxia in fetus. This paper describe non-invasive technique employing single channel magnetic induction technique. The simulation was done to determine the best range of frequency value to detect biological tissue and tested with different value of conductivity value
