Making devices to help in the fight against cancer

A bit blurry and some artifacts, but PROOF that our MFM uncollimated #SPECT system works!!! (Axial, sagittal, coronal of a flat uniform disk ; 1mm cubic voxels).

I won the #LSINW22 fast-pitch Audience Choice Award for my pitch on the PRRT Vest! Thanks to all who got us here! #uwmedicine

[Larry Pierce @LarryPierceUW]

The MFM uncollimated #SPECT system vibrates an attenuating wand between the patient and the detector. The changes in detector signal allow us to recover the high-frequency image components. Happy to talk further...ESPECIALLY TO INVESTORS! #raisingmoney

This vest contains SPECT sensors to measure PRRT organ dosimetry and results are sent over WiFi. Dosimetry is within 3% of true. No need for clinical SPECT scans for PRRT dosimetry, in-home dosimetry is here! https://t.co/EFJajEquyZ

A nice image from our MFM uncollimated SPECT system (simulated data, we're raising money for the prototype now). #SPECT #nuclearmedicine #UWmedicine

Robert Miyaoka (UW) just got 1st place for best poster on Physics Instrumentation, and Data science at @SNMMI for his poster on experimental results for the PRRT Vest!

The MFM single-photon imaging system for nuclear medical imaging:

NO MORE COLLIMATORS!!!

@UWComm @UWMedicine @UWCoMotion

[Larry Pierce @LarryPierceUW]

We finally have the patent application for MFM in and have go-ahead to start publishing results!!!

MFM is a new single-photon imaging modality that uses moving attenuators to recover high-frequency data from the object being imaged.

Cold spot imaging tests (1 cm diameter) for MFM-SPECT:

TRUE ZEROS!!! (We'll keep working on the contrast...)

An historic day for uncollimated MFM-SPECT: UNDER 2.0 mm resolution!!!

#MFMSPECT #PrecisionSensing @UWMedicine

[Larry Pierce @LarryPierceUW]

HUGE WIN for the PRRT Vest today:

Real radiation measurements on the Hauck phantom show organ dosimetry to within 3% of truth!!!

1.0 mm image resolution using uncollimated MFM-SPECT!!!!!

Thanks to UW CoMotion and the Washington Research Foundation!

Goodbye Collimator…. HELLOOOO SENSITIVITY!!!

Reconstruction tests from our new Un-Collimated MFM-SPECT are looking pretty good!

In February, Robert Miyaoka and I came up with an idea for a new SPECT scanner. It has over 1,000 times the sensitivity of current SPECT.

Today, @UW CoMotion awarded us $50,000 to build a benchtop prototype of the new SPECT camera!

We are working hard on our R21 grant to get ready for patient trials with the PRRT Vest!

@Globeseek Mazel Tov to your son and to you!

[Larry Pierce @LarryPierceUW]

I forgot to add @mikemorrison to my original tweet, he invented the new poster format! Thanks Mike, it was a great success!

[Larry Pierce @LarryPierceUW]

Had a great time at #NANETS2019 showing off the PRRT Vest! #prrtvest

[Josh Mailman @Globeseek]

FDG may have a role as a prognostic factor for PRRT. Retrospective look at 500 patients. #enam19 https://t.co/ijy2tjWH9D is doing a multicenter study on this as well.
