The meeting notes and supplemental information regarding ultrasound technology, research, manuals are posted.
Meeting with
James A. Zagzebski
Tuesday, November 01, 2011
This was an initial meeting to build the relationship between the folks at Medical Physics (and Imaging) and the CELL researchers. My notes reflect the trajectories of topics that emerged from this meeting. Since my base knowledge is limited, I have tried to list as much information that will serve to jog people’s memories of the meeting as well as providing some factual context. Some information may reflect my novice understanding of the procedure, equipment, application. Apologies if I failed to capture important points of the discussions.

JZ inquiries about the types of questions/problems we are interested in.
Some responses included the following:
Range of tongue positioning for speakers of different languages;
Range of motion occurring in the glottis
Capturing imagery to detect and measure adduction and abduction.
JZ:
1) Ultrasound technology is still not very good at capturing vocal chords; capturing speed is still an issue. The current machine can capture at ~ 150 frames/ sec, maybe as much as 200 frames/sec; when frame freezes @ 120 Hz
2) Recommends spending time playing with the machine and let it explain what it can do through experimentation getting used to shadows, landmarks, multiple moving parts;
3) Also recommends studying anatomy, to include cadaver studies;
4) Recommends using the 3D probe (located in the breast clinic).
Technical topics of the conversations while we were “looking” at talk:
Brief discussion on current transducers; JZ refers to the one he is using as curvilinear;
TP: Topics of seeing stiffening/slackening; ER: rocking of cricoid cartilage
Question of what we are seeing move: false vocal chords (ER and JZ bet a beer on whether we are seeing real or false vocal chords);
JS: Need to determine the visual reference of unenergized state.
JZ: Two types of zoom and data presentation:
1) Read = data is redisplayed
2) Write =combs down data
Clinical avenues that could lead to collaborative studies
ER: Mentions locating/using the tendons of the adenoids as landmarks.
JZ: Brings up clinical work on polyps, diagnostic and therapeutic uses of ultrasound in throat disease and injuries;
