Pauli Tuovinen and Matti Mikkola: Special assignment interim reports
You are warmly welcome to hear these special assignment interim reports on Tuesday 17 April 2018 at 16.00 in F227, Rakentajanaukio 2 C, Otaniemi.
Speaker: Pauli Tuovinen
Type of talk: Special Assignment presentation interim report
Title of talk: Quantification of cavitation events near a vibrating tapered structure
Supervisor: Prof. Heikki Nieminen
Place: NBE, Medical Ultrasonics Laboratory MEDUSA
This presentation is an interim report on a special assignment project.
Fine needle aspiration biopsy (FNAB) is a method for collecting samples of biological tissues. These samples are analyzed and used as an important tool in diagnosis of cancer. However, as much as 34% of FNABs fail resulting in delay in diagnosis and treatment.
MEDUSA is developing an ultrasound-enhanced fine-needle biopsy (USeFNB) method for increasing the yield during the biopsy. One of the sound-tissue -interactions possibly contributing to enhanced yield is cavitation. The goal of this special assignment is to apply image analysis algorithms to quantify cavitation events in water observed with ultra-high speed camera. The progress of the analysis is reported and preliminary results are presented.

Title of talk: Ultrasound-enhanced fine needle biopsy device for animal trials
Supervisor: Prof. Mikko Alava
Instructor: Prof. Heikki Nieminen
Place: NBE, Medical Ultrasonics Laboratory (MEDUSA)
Fine-needle aspiration biopsy (FNAB) is a procedure for sampling tissue for diagnostic purposes. In FNAB, a thin needle is inserted into the target and translated in order to collect a small volume of tissue into the needle. It is a less invasive alternative to core needle and surgical biopsy, but can fail due to insufficient sample size. Ultrasonics can be used to enhance the yield. The goal of this study is to improve the current ultrasound-enhanced fine-needle biopsy prototype so that it could be used for small animal trials. Current state of the project and preliminary results are presented in the seminar presentation.
