   1.                                                   We note your response
to prior comment 7 but are unable to locate changes addressing the
                                                        comment. As previously
requested, please revise the Background of the Business
                                                        Combination section to

negotiations.
   2.                                                   We note the revisions
made in response to prior comment 10 and we reissue the comment

to clarify why HealthCor's model reflected a materially reduced

changes addressing
         the comment. As previously requested, please revise the April 13 entry
to clarify the
         actual combined dollar valuation proposed by Hyperfine and Liminal,
and tell us whether
         that proposal provided separate valuations for Hyperfine and Liminal.
Certain Projected Financial Information, page 117

4.       We note your response to comment 15. Please address the following:
             It appears that one of the material assumptions underlying
projected revenue growth
            is the expected recurring revenue from the subscription-based
business. Specifically,
            as the base of installed units grows, the cumulative carry-over
effect will result in
            increased revenue each successive year as the business continues to
grow. Please
            further expand your disclosures to further discuss the assumptions
underlying the
            different projected revenue streams, which appear to be unit sales
and subscription-
            based services; and
             As previously requested, please explain how management and the
Board considered
            and relied upon these projections, particularly in light of the
limited historical
            commercial operations of Hyperfine, Inc. and Liminal Sciences, Inc.
5.       We note your response to prior comments 17, 18 and 19 but are unable
to locate changes
         that address the comments. As previously requested, please revise to
address the
         following:
             Clarify whether the financial projections disclosed here were the
only projections or
              material financial information that Hyperfine and Liminal
presented to the HealthCor
              board for purposes of negotiating the terms of the Business
Combination Agreement.
              If not, please disclose such information, forecasts and/or
projections;
             Describe how the parties were able to negotiate what proved to be
the final valuations
              and reach agreement on other material terms in May if HealthCor
did not receive
              financial projections from Hyperfine and Liminal until June 10;
             Disclose what the HealthCor board did with the projections it
received and whether it
              used these same projections, or altered ones, in its financial
model(s) and analyses.
Recommendation of HealthCor's Board of Directors, page 124

6.       We note your response to prior comment 20 but are unable to locate
changes made in
         response. As previously requested, please revise to clarify here
whether HealthCor   s
         Board conducted any financial analysis or analyses that support its
determination that the
         merger is in the best interests of shareholders and its recommendation
to vote for the
         business combination, or advise.

7.       We note the revisions you made in response to prior comment 21. We
further note that
         counsel does not appear to opine on whether or not HealthCor is likely
to be classified as a

will be. Counsel's
         opinion should not assume the tax consequence at issue or any legal
conclusion
         underlying the opinion. Please revise the tax opinion and related
sections accordingly.

Unaudited Pro Forma Condensed Combined Financial Information, page 164

8.       We note your response to comment 27. It appears that the pro forma
statements of
         operations do not include certain expenses that are not expected to
have a continuing
         impact, including nonrecurring management compensation expense
discussed in Notes
         3(h) and (i) on page 174 and transaction costs discussed in Note 3(b)
on page 171. We
         remind you of the updated pro forma financial information guidance
provided in SEC
         Release 33-10786, which amended Article 11 of Regulation S-X, under
which it would
         appear these expenses should be reflected in your pro forma statements
of operations.
         Please revise your pro forma statements of operations or further
advise. Refer to 11-02
         (a)(6)(i)(B) of Regulation S-X.
9.       We note your response to comment 28. The most significant adjustments
on your pro
         forma statements of operations are for compensation expense related to
various equity
         awards. In this regard, please address the following:
             We continue to believe additional disclosures should be provided
to discuss the most
             significant underlying assumptions used to determine the
compensation expense in
             Note 3(f), 3(g), and 3(h)(2). For example in Note 3(f), you note
that the grant date
             fair value of the awards were estimated using the Monte Carlo
simulation; however it
             is not clear what significant assumptions were used in the
simulation to arrive at the
             grant date fair value; and
             It appears that adjustment 3(f) only reflects certain Earn-Out
shares discussed on
             page 168. Please further clarify in your disclosures the amount of
shares included in
             this adjustment as well as how you determined which shares to
include.
10.      We note your response to comment 36. Your response indicates that the
only recent
         equity issuances were Hyperfine options granted in April 2021 and
Liminal options
         granted in May 2021. As previously requested, please help us better
understand how the
         fair value of the common stock of Hyperfine and Liminal which was used
to to value
         these issuances reconciles to the valuations as indicated based on the
terms of the
         Business Combination. Please also clarify whether these are the
options discussed in Note
         3(h)(2) to the pro forma statements of operations.

12.      We note the revisions you made in response to prior comment 32 on
pages 195 and 196,
         in particular the disclosure in the second paragraph on page 196 that
"Liminal has not
         commercialized or obtained regulatory authorization for any of its
products and its
         operations to date have been limited to developing its technology and
products." Please

13.      We note your response to prior comment 34 that Hyperfine will be
obligated to pay MGH
         a percentage "in the low double digits." Please revise to disclose the
rate Hyperfine will
         be obligated to pay within a ten percentage point range.

14.      We note your response to prior comment 30. Please revise to clarify
whether any of the
         executive officers or directors following the business combination
have worked with the
         Liminal business and how many current Liminal executive officers and
directors will join
         the combined company.

16.      We note your response to comment 39. Please address the following:
             Your disclosures on page F-49 indicate that manufacturing overhead
costs primarily
             include the allocation of labor costs incurred related to
inventory acquired or
             produced but not sold during the respective period. Please better
clarify the nature of
             these labor costs; and
             Please help us better understand why charges associated with
writing inventory down
             to lower of cost or net realizable value are also included in
overheads rather than
             being recorded directly in cost of sales.
             As previously requested, please explain herein or within
Management   s Discussion
             and Analysis, why you had $213,000 write down in inventory during
the year ended
             December 31, 2020 as this inventory was purchased during the same
period.
